The FUNK 3 is an all new design inspired by Zun’s vision and our latest generation performance suits. In the hands-free category, no other suit delivers as much range, speed, and glide performance - all of which translates to increased power and agility in maneuvers.

The F3 is for wingsuit pilots who want an easy hands-free design that delivers a higher level of performance.


Stephan “Zun” Zunino was a critical part of the F3 development and his vast experience with gripperless suit designs drove the development of this suit. The F3 is not just an evolution of the 2 - it is a ground-up design based on Zun’s vision and our latest suits such as the FREAK 2 and ATC.

Modern performance features have led to a noticeable increase in carving and backflying precision, agility in transitions, and speed / glide performance.


We recommend comparing the F3 with other similar designs. Contact us for a demo today, and compare the F3 standard features included in the price: Rubber BASE soles, Backfly Inlets, Hook Knife, Storage Pockets, Belly-cam access, and more.


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.

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 F3 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 harness 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.
