The Biggest Little Suit, Ever

  • The only intermediate class suit that flies easily with advanced designs
  • Unmatched performance in the intermediate class
  • Perfect for pilots moving up from beginner suits
  • Experience real flare power, glide, and speed
  • Easy step up for pilots of “gripperless” designs
  • Clean and simple BOC access

The ATC is the first suit to truly span the gap between “big” and “small”, while flying comfortably in both categories. It has enough performance to fly a formation with FREAKs, yet it’s small and nimble enough to flock easily with SWIFTs and FUNKs. This new design is intended for any pilot who wants a “small” suit with extra range and speed. Our team pilots agree that this "mini-FREAK" has surprising performance for its size.

Although it is in the same range of total surface area as the FUNK, the ATC has more speed and glide. Real-world example: the ATC can be flown together with FREAKs. At the same time, it is easy to fly together with smaller suits.

Like all of our newest designs, the ATC benefits from the technical advances made during the C-RACE development over the past two years. The same low-drag compression inlets and profile/planform research that took Squirrel pilots to the top of every major competition in the past two years are contained in the ATC.

We’re very excited about this new concept and we’d like to thank our team pilots who helped us develop it. What started as powerful work tool for pro pilots has turned into a highly versatile suit that will appeal to any wingsuit pilot of beginner-intermediate ability and up. The ATC’s power and range will surprise you!


In 2012, Squirrel introduced the first 3D reinforced inlet, which has now been adopted by other manufacturers. The new Compression Inlet builds on this innovation with higher intake efficiency and lower drag. The aerodynamic shape, finely tuned size, and intake feed are all the result of extensive R&D.

Performance Planform


The ATC’s planform is based on the FREAK and other higher performance designs, with an extended mid-chord wing root (extra surface area around your hips). The total surface area puts it closer to small surface designs. The result: easily accessible performance.

Rapid Arm Deployment


Rapid Arm Deployment. A carefully designed forearm segment of your leading edge allows improved access to your PC at pull time, and your risers / toggles during opening. This helps to make BOC access and early riser control safer and more intuitive than traditional designs.

New Nutsack


The new nutsack is accessed from the same location, but is a panel-wide flexible hammock which allows more storage and also keeps items higher / closer to your CG, and further from the leg inlets. Store your gear closer to your center of gravity without having it affect the fit of your suit.


Lightweight, durable, and more stable than mesh, Porcher Sport Skytex is renowned for its mechanical stability. Helps to reduce overall weight and pack volume.

One-Zip Attachment


The ATC attaches to your rig with one simple zipper for quick and easy rigging. An adjustable lateral slot lets you customize the lateral position for your rig, or any other rig in your size range that might be used with your suit.

Get Stiffie


The bottom surface of the leading edge is Mylar-reinforced to maintain profile structure and proper feeding of the inlets.


All of our suits are built to the most exacting specifications, and tested for airtight symmetry in our production facility at multiple points along the construction process. The end result is the highest build quality that we have ever seen.

Main Surfaces

Main Surfaces

Our main concern was finding an ideal ratio between weight and durability, along with high mechanical stability and good results in stretch and tear tests. Our main surface fabric is a 210D Ripstop, with very low stretch, and a good rigidity to comfort ratio.

Leading Edge Dacron

Leading Edge Dacron

Proven to be highly durable and dependable in other airsports applications, Dacron’s performance was thoroughly tested by team pilots before and during the RedBull Aces event, which was won by a Squirrel proto featuring this material.

Internal Ribs

Internal Ribs

All ribs are constructed from the renowned Porcher Skytex 40, which has an unparalleled stability-to-weight ratio.

Leading Edge Mylar

Leading Edge Mylar

We offer two choices for wing surface Mylar reinforcement:

1. Porcher Sport (white / translucent). This is our standard option.

2. Dimension Polyant Carbon-Graphite (black / clear). The highest quality laminate on the market, with a carbon and graphite weave. It's black, and it's more rigid, but there is not a measureable performance difference over the Porcher mylar.
