"After putting several flights on it, I could not wait to write this review: From the first flight it felt like an old friend! Comfortable and familiar, but with so much potential!! The Swift prepares you so well, that when the ATC is on and flying, it feels natural and inspiring. In the usual Squirrel approach, the devil is in the details when it comes to progressive evolution of the suits - small refinements make a huge difference: I love the reengineered wingtip grippers for a more comfortable hand position that makes maneuvering and transitions much smoother and more efficient. The tuck tabs for leg zips’ drawstrings (instead of the velcro) is the type of attention to detail that makes these suits what they are, and those are just the design elements. When it comes to flying, the ATC4 feels very balanced in pitch and roll, allowing for seamless control input. Right after the first flight it felt familiar and comfortable enough to roll, back fly, and push the pitch envelope. What excites me about the ATC is that it’s just the tip of the iceberg as far as the performance of the suit and how much I will learn in it. "

"We had a blast putting the new ATC 4 through its paces. The very unobtrusive carbon end cell gripper helps us to focus on flying out body, not our hands. The center of lift feels more balanced and easier with more deliberate pitch control, and less resistance in the steeper pitch angles. It seems to have plenty of speed to make mixed groups play well together, and delivers power for flares. The internal pressure is appropriately firm, and remains that way throughout transitions and backflying. You guys really squeeze a lot of power into these suits, I can’t wait to put more jumps on them!

"The ATC 4's appearance can be deceiving, and it has proven to be the Swiss Army Knife of my wingsuit collection. Its remarkable versatility makes it a go-to tool for various types of flights. Whether you're shredding around clouds, formation flying, doing XRW, instructing students, executing butter-smooth transitions, or hucking altitude gaining flares— it consistently delivers with efficiency, stability, and impressive power. It feels like it's on rails as it glides through the sky, yet boasts a range that rivals many larger wingsuits while maintaining the forgiving nature of smaller ones. In short, it’s a valuable addition to any toolbox and I highly recommend it to experienced pilots of levels. "

"Seriously, you guys have outdone yourselves with this suit, and I have no idea how you’ll improve upon it. It’s SO fast. Transitions are also really smooth (as to be expected with the mono chamber). The most noticeable changes to me though are in the areas where I previously thought the Freak series surpassed the ATC as a best all around DZ suit for me, personally. It has a lower bottom end for me now, which I love. Whatever you guys have done in improving the ATC 3 has really increased range and decreased stall speed. I absolutely love it. Lastly, the improvements to the ATC 3 have made this the absolute easiest pull I’ve ever experienced. Even completely exhausted after pushing the suit as much as I could, pull time was effortless."

"The new suit is absolutely fantastic! I actually find it much easier to control and maneuver than the Swift. That may be because this suit is custom fit to me and the Swift was a rental, but regardless, this suit is like a dream!

When I first tried on the suit I was a little concerned that perhaps there was a little too much room around my waist. The suit was tight around my stomach and back, but felt kind of loose on the sides. However, this changed when I put the rig on with the suit, and then it felt perfect, so the fit is wonderful!

During flight it felt intuitive and responsive and my goodness how much flaring power it had! I look forward to learning more and more about flying this suit!

I have attached a couple shots from my first flight with it. I think the helmet somewhat obscures my smile but I can guarantee you it was there!

Blue skies!"

"Wow! This suit is amazing! I can’t believe how intuitive and natural it feels to fly. And so much fun! It feels even more stable than my Swift 3, which I love as well. I couldn’t be happier with it and I’m looking forward to progressing with it!

The fit feels great! At first I was unsure about the arm length as it’s a bit longer in the arms than my Swift 3 even with the same measurements, but once I jumped it, I realized they fit even better than my Swift."

"Good morning Squirrel-Team! :)

The suit fits absolutely perfect!!!

When I first put it on, I thought the arms would be a little too long compared to my Swift1, because I cannot reach the grippers direcly, only very close to them (The swift was not made for me, so maybe the arms were just a little too short for me on that swift). But after I read the manual (there is a picture explaining how to held the grippers correctly) it turned out the suit fits perfectly and also the arms are exactly the correct length! :D

I finally jumped my ATC2 the first time and wooooooow... this suit has soooooo much more power compared to the Swift!! I was a little nervous before the exit, because it looks so much bigger than the Swift. But all worries were gone immediately after the exit.

From the first moment on the ATC2 was VERY stable and really easy and fun to fly. It has so much power and the flare at the end feels really great (also looks pretty cool on the video :D) The BOC access and pull were very easy. Thank you very, very much for this amazing suit!! :) I'll definetly come back to you again, when I'm ready for the next step (to the Freak). Special thanks also to Mike for the great support during the order- / shipping process! ;)"

"We got our ATC3s in last night and I got to fly it for the first time today. I loved it! The feeling was very reminiscent of the Freak 4, just balanced ever so slightly differently. The internal pressure is exactly what I was hoping for in an intermediate suit. Precise control through the transitions, and a naturally high airspeed. The flare was powerful and pull time was so effortless with how the arm wing internals are tuned. "

"I highly recommend the ATC for anyone looking to step up their game in the wingsuit world! It’s fast, powerful, pressurized, agile, smooth, stable, forgiving. The ATC sits well placed between the Funk and the Freak on the chart and brings the best attributes from both suits, you will find more speed and flare power than the Funk but you will be pleasantly surprised by the stability and comfort while transitioning, barrel rolling, and back flying. I have spent a lot of time flying the Freak and love it but I wanted something smaller to be able to fly with all sizes of suits for coaching purposes, I not only found my self able to fly with smaller suits as well as the Freaks but I started improving skills I was a little timid to try on the Freak, such as transitioning and barrel rolling my "weaker" less used direction, working on very steep back dives, back flares as well as mixing in some high speed carving/head down flying. Thank you Squirrel for making the ATC!"

"After putting about 60 jumps on the ATC, the qualities that still blow me away are its speed and energy retention. I was worried when I ordered it that I would have to fly the balls off of it to stay with big suits, but it's so fast and efficient that even with less surface area than a Freak, it's no problem. It prefers full-flight, but as long as you keep it at a nice angle of attack when it brakes, it's no problem. It shuts down easily with small suits, and it’s so comfortable at speed that chasing students and getting down to smaller suit groups is a breeze."

"The ATC is the perfect all-around wingsuit. Backflying and dynamic maneuvers are a breeze. I was also very impressed with the speed and range that the suit offers. This suit is extremely fast for its size! I fly it all day long with Freaks, and can't even tell I am in a smaller suit. The flare power also surprised me, as I am able to gain almost as much altitude as my Freak1. It can also easily fly with Swift 2's and Funk 2's, without having to de-power the suit much. The ATC has quickly become my go-to suit. I love it and can't wait for what you guys will come up next!"

"We need to have a very serious chat about this suit. It's amazing! I love it! I got it primarily for coaching and organizing and its perfect. Previously I was using my Freak2 to coach and while I had no problem staying with Hatches it was a bit of work. Moving from the ATC to the Freak is so intuitive and it likes to fly sooo much better with small suits and clearly has no problem keeping up with big ones. My Freak2 is still my favorite suit but as much as I organize I can easily see myself jumping the ATC a lot more. Thanks again!"

"My new suit fits perfect. The first 6-8 jumps I had to get the feeling of it, but after this I really enjoy flying it. Here is a link to my first ever XRW jump: https://www.youtube.com/watch?v=Svf-3XbxHGc&t=4s"

"Thank you for the amazing machine you sent me..... My ATC, I got in the beginning of the season fits absolutely perfectly and I use it all the time while coaching. You guys made me love wingsuit flight, the whole activity and I’m more than happy to live this entire adventure thanks to you. The easiness, safety, and fun that come with these suits make them much more accessible that they were before... you changed the whole activity for the better."

"The ATC has been amazing so far! I've put about 10 flights on it and it's incredible how intuitive it is to fly (even on its back) and how easy it is to fly with small suits or my friends in Freak 2's."

"The new squirrel ATC, well I definitely have a lot I can say about this suit after testing it in all kinds of waters during flock and dock! first off the fit is great as always, very comfortable suit both in the air and sky and cannot ask for a better feel then the custom squirrel fit wingsuits. Now for the fun review....how it flies! well first off I was extremely surprised how much power this thing holds! yes, i knew it was a baby freak but man she has more power than I expected for its size platform, and this power makes it fairly easy to keep up with freak/freak 2 sized formations at normal and near max speed. The ATC is even capable of doing XRW which I found amazing! keeping up with slow record speed flocks and smaller suits is also quite easy, just recommended to depressurize the suit lightly to make the work easier for you. Backfly transitions are as smooth as can be, and the suit really likes to have some speed on its back which is great! overall this suit is everything I was hoping for and a tad more as it has a ton of float power and speed potential for its size class and controlling it is very easy!"

"I am coming from the _____ and Funk 2. More range than both of those suits and almost easier to fly! It is so perfect for coaching FFC courses. I can fly with a wide range of suits! It is fast when you need the speed, but also easy to fly slowly. Everything I read and heard about on this suit is real, it is amazing. Thanks and congrats for this perfect wingsuit."

"I wanted to let you know how I'm liking the ATC! The suit fits perfect. I did a handful of coach jumps for my friend who is flying a Swift 2. I loved the range that I had on her and it made flying with her smooth and easier to give her feedback. I spent the rest of the day flying with Freak 2, Aura, Colugo 1, and Funk suits. I was able to fly with them great and I'm loooooving the speed in the ATC.

The transition from the Swift 2 to the ATC was seamless. I immediately noticed how much more responsive the ATC was compared to the Swift 2, but it wasn't intimidating, only exciting!

Absolutely in love with this suit. I'm very excited to be able to fly with small suits and big suits. I won't have any friends left out on jumps this summer! I'm excited that people at our drop zone flying small suits will feel less pressured to quickly progress into large suits since they dominate our drop zone.

Thanks for the awesome suit! You guys are the best."

"This weekend I finally got the chance to jump my new ATC, and what a ride!! I’m in love with the suit and the fit turns out to be great! I have to admit I was a bit nervous before my first jump but the suit behaved predictable enough and wow does it go fast. I made a bunch of solo jumps first to figure out the suit and fly it in different angles and stuff and although I feel I still need to adjust and learn a lot more how it responds, I’m confident now that ill work it out.

Also everyone on my home DZ responded really positive to how the suit looks and feels and its funny since I’m the only Dutch guy (as far as i know) that owns the ATC as well as the Epicene (incl. SkySnatch). I’m very happy with the whole setup! Have a great week and blue skies!"

"Have to say that this suit is the best wingsuit I have ever tried. Amazing!!! Powerfull, Easy and stable to fly... Awesome!!!"

"This suit is so awesome, it’s so good in steep angles and fast flight with high performance pilots, but also perfect for me for coaching smaller suits. It’s crazy how much performance there is for how easy it is to fly."

"Check out the ATC review in SkydiveMag, by Val Sobol."

"My story is intertwined with the history of ATC, and over the years I had the opportunity to fly all the ATCs that were launched. The ATC 3 is incredible! I don't have to worry about whether the student is going to use a beginner, intermediate wingsuit or a tracking suit, the ATC 3 flight envelope guarantees the possibility of flying extremely slow or fast at any angle without any worries. The accuracy of the movements guaranteed by the MonoChamber system is absurd, sometimes I have the impression that there is an automatic transition button on this wing :-)

Definitely the ATC 3 is the right choice, not only to make the transition to FREAK, but also to have it for life as a Swiss Army knife that will help you fulfill any mission.

I appreciate the opportunity to contribute and continue using the ATC 3 in my wingsuit school."

"I’ve put around 70 jumps on the suit and it feels great. I love it. It fits me perfectly and is very comfortable in the sky. Pull time is comfortable and easy. The performance is great. It’s easy to fly with small suits like a Swift or to fly with bigger suits also. Back flying is effortless! Excited to see what the Freak feels like next! Thank you!"

"I finally jumped my ATC 3. The fit is perfect! My instructor told me to fly it like my Swift 3 and that is what I’ve done. I felt like I was on a rail, but with a lot more power. It was very easy to switch from the Swift to the ATC3 and the movements were very intuitive. Well done. "

"I've done about 50 jumps on my ATC 3 and I absolutely love it. It fits like a glove with the perfect amount of tension when I point my toes. Arm length is perfect and great fit on the torso. I'm extremely happy with the way the design and print turned out with the SuperCustom option. My suit pressurization between the ATC3 and previous suits (Funk and ATC 1) is a night and day difference. It’s been so much fun. Most recently, I was able to stay with and fly relative in my first 9-way with all Freaks. Flying my custom ATC 3 has been a world of difference from flying anything else."

"SQRL, I have used my new ATC3 and I love everything about it, AMAZING! The quality is 100% what you dream about in a wingsuit and was noticeable as soon as I opened the packaging. All the features are amazing and complement safety and efficiency perfectly (especially the quick clips for holding leg wing up). The fit is perfect and it flies amazing. GREAT JOB TEAM!! My order even arrived much earlier than expected, something that is obviously very rare in the skydiving industry in this day and age."

"I received my ATC 3, what a high quality! The size is perfect, thank you very much for the job! I started BASE jumping in 2007 and I only used tracking suit until 2021 because I thought it was enough… Now, after many jumps on my Funk 2 since 2016 and now 15 flights with my ATC from a plane, I have now completed 8 BASE jumps. From the start of the exit, I was very comfortable and much more glide! Kiss from the Alps!"

Now I’ll be able to take everything I learned about performance flying, flocking, back flying, heli-jumps and large formation flying and build on that foundation to take my wingsuit flying to the next level with the ATC 3!"
