The best choice for your first tracking suit

*The Sumo 2 will be replaced in the first half of 2020. You may pre-order a Sumo 3 now. We expect Sumo 3 pre-orders to ship before summer 2020.

Stability, Speed, and Ease of Use

  • Solid start and glide performance for BASE
  • Reduced drag from better shaping, new inlets
  • Backflies easily, thanks to new inlet design
  • 2018 design updates for Improved durability
  • Ideal balance between volume and stability

The SUMO 2 builds on the success of the original SUMO, incorporating feedback from our team pilots and customers. Whether your tracking mission is to develop wingsuit skills or to progress in the BASE environment, the SUMO 2 is the answer. This new design is ideal for entry level trackers or for experienced trackers who prefer a two-piece suit. If you are an experienced tracker looking for the maximum in range and glide, we recommend the SAUSAGE.

The SUMO 2 is a direct evolution of its predecessor. It features similar overall volume, but we have refined the aerodynamics for reduced drag by changing the inlet shape and positioning, and optimizing the location of the leg wing thickness. A new inlet design yields less drag, more efficient air-input, and makes the suit back-fly and free-fly capable.

Thanks to a slicker and more agile feel, the SUMO 2 is easier to control in steeper track angles and is overall a more forgiving yet higher performance design. Jumpers with SUMO experience will instantly notice that the SUMO 2 settles into a naturally steeper and more efficient angle, and is easier to transition from flat to steep AoAs.

The Squirrel No-Wobble System has been carried forward from the original SUMO, as it has proven to provide a level of precision that set the SUMO apart from other two piece designs. The NWS is optional, but, when used, gives a compact and precise feel in tracking maneuvers.

Overall, the SUMO 2 provides what we think is the ultimate balance between volume and stability, and is the perfect choice for a first tracking suit. The SUMO 2 is built to the same high standard that has made Squirrel wingsuits the benchmark for quality in our sport.

Force Feed

In tracking as in life, the power is in your pants. The SUMO 2 pants are powered by an array of mylar-reinforced inlets which rapidly inflate and maintain pressure inside the suit.

Quick Starts


The SUMO 2’s new bi-directional arm inlets provide rapid inflation and feed the suit at all angles of attack.

New Low Pro Inlets


The Sumo pant inlets have been optimized to reduce drag while maintaining solid internal pressurization. All inlets are reinforced with Dimension Polyant Carbon/Graphite tri-laminate. Smaller leg inlets have increased speed and give the suit a slicker and more agile feel.



Inside the pants at the knee, we have added a Velcro enclosure which anchors the pants to your leg, reducing pant-leg wobble and increasing control and performance. This is now a proven feature, and gives the suit a more precise and solid feel when maneuvering in high speed tracks.


The high collar, cinched wrist, and extra-long torso help to reduce leakage and maintain pressure in the jacket.



Four zipped chest pockets provide plenty of phone / emergency electronics / gear storage, and the jacket is lined with mesh and lycra for comfort and structure.


The knees are heavily reinforced in Cordura, with 5mm of closed cell foam padding for protection and structure. The Cordura panels are now custom color selectable.

Toe Tension


To maximize fit performance, three toe-tension settings are available, using a lightweight and simple buckle/strap adjustment.


Durable, strong, custom colored 10C YKK zips are used on the closure of jacket and pants.


The SUMO 2 is built to last, and we stand behind all of our products. We will repair or replace, free of charge, any SUMO 2 that suffers damage as the result of normal use.

  • "I love my Sumo 2. The suit is powerful and inflates quickly. It is easy to fly. I fly it in the Sky, BASE and tunnel arenas. It is also free-fly friendly. Head down is smooth and slow speed. Head up takes some more practice. Over the head transitions are smooth. Over the feet transitions take a bit more commitment because of the balance of the suit.

    Tracking in it is amazing. As soon as you hit terminal it takes off like a sling shot. It likes to fly steep and fast in an angle flying position for maximum forward drive. At the exit point it gives me the confidence to know that I will be pulling far clear of any obstacles. I have no problem throwing an invert from Exit 6 and still pull over the water with this beast. I recommend it to anyone."

  • "Compared to my ____ tracking suit, the SUMO has quicker inflation and a quicker start, which is the most important stage in getting a good track (especially in the valley) and also makes it safer as you are getting away from the wall faster. I also feel it has more range at the bottom as well…

    I made 400 BASE tracking jumps in my ____ suit, so you could say I was very used to it. On my first jump in The SUMO I made it as far, if not better than, my best jump in my ____ from the High Ultimate. After a bit of change in technique and more jumps in the SUMO, I could go a lot better and I get a lot more out of this suit! Have FUN!"

    -Lorenzo Buzz
  • "I received the Sumo (thanks a lot) and gave it a few tries right away. I did my best track from the 1st attempt, so the suit is definitely the best suit I've tried, and is as well the most powerful! You're wise to encourage people to skydive it a lot before Base, because I find it harder to fly correctly track pants than wingsuit, like every big pants I've tried!"

    -Vincent "Le Blond" Descols
  • "The quality is UNREAL, I can't believe how awesome the suit looks! Every stitch is picture perfect and the suit fits like a glove. "

    -Andrew Toyer
  • "Did 8 jumps (skydives) with the SUMO this weekend. Very solid, powerful & compact feeling, especially with the no wobble system, it feels much more precise in steep turns/angle then any other tracking suit. Good balance between agility and performance."

    -Cedric Dumont
  • "The Sumo flies super nice and is easy to control, only done 5 jumps on it now in the past week but am really enjoying the progression and feel of the suit. "

    -Simon Fasnacht
  • "Never thought I could have this much fun in a suit. Definitely my favorite suit I have flown yet."

    -Lucas Paskiewicz
  • "The inlets work perfectly at all flight angles. It is very fast, and has a lot of stability in a wider stance."

    -Hartman Rector
  • "This thing rocks. I can't believe how much forward speed it has on the lower end. It feels so solid!"

    -Scotty Bob
  • "After just a few jumps I can now say that 100% this is the best tracking suit that I have ever flown. It is powerful, sensitive, and easy to learn from the start. It has massive potential. Here is video from one of my first jumps, flying to the road at High Ultimate.

    Also, the closing flaps of the container are super nice and stay in position. Not like on a _____, _____."

    -Leonardo D.
  • "I’ve been flying the Sumo for a about a month now and am continually impressed. For everything BASE my priorities are safety and ease of use, and the Sumo is all that and then some. I’ve flown several Tracking suits (both one and two piece) over the last few years and I can safely say that the Sumo wins hands down for stability, pressurization and pilot interaction, and doesn’t compromise an inch of performance to achieve it. In fact the more I learn about the inputs it needs from me, the more personal bests I keep surpassing.

    I was a little nervous taking out of the plane for the first time. Not only was I un-current in a Tracking suit, I was also an un-current skydiver. But within the first 10 seconds of flight I knew I would be comfortable flying it from a cliff (after years of prior training and experience of course!). Such massive levels of rock solid stability were previously unseen in any of the Tracking suits I’d flown and this gave me the confidence in control that I require to happily BASE anything.

    In the Base environment I’ve found it a perfect tool. Quick inflation provides opportunity for quick starts and in the right hands with the right technique I believe it can take you further than any other two-piece on the market, and will do it more comfortably and safely.

    Of course as with any tracking suit, the pilot is still everything. A bad pilot will fall like a brick and a good one will fly like they were born to it. As such I much strongly remind everyone that a vast amount of prior experience in the BASE tracking environment or a significant amount of skydiving in the Sumo must be considered before taking it of a cliff. But with those things considered it would be a great first suit, if not the best first suit currently on the market for either environment."
