C4

ACCESSIBLE SPEED & POWER

  • New Seamless Leading Edge
  • Excels in the BASE environment
  • Easiest & most comfortable high-performance suit
  • Near C-RACE performance with FREAK-series comfort

Since its launch in 2017, the C3 has become known for its incredible balance of performance and comfort. The C4 offers next-gen performance with the same ease. No other suit delivers this much speed and glide with such incredible ease of use. With FREAK-series comfort, and near C-RACE speed, the C4 is a capable and fun to fly suit for intermediate-advanced wingsuit pilots.

Our mission for this suit was to put as much performance from our competition line as possible into an upper-intermediate category design. If you are intrigued by high performance suits but still want intermediate level comfort and passive safety, then the C4 has what you're looking for.

The C4 is not designed for freestyle flying. If you are interested in an all-around fun suit, then we recommend the FREAK series. The C4 is for performance flying in the skydiving and/or BASE environment.

Compared to the FREAK series:

  • Same stability and comfort.
  • Same ease of use for BOC and riser access.
  • Loves to fly steep, like a FREAK.
  • Best-in-class flare power.
  • The C4 is not designed for freestyle flying.

Compared to the C-RACE:

  • Similar performance (95% speed, 90% glide, 90% sink rate).
  • Easier deployments.
  • Easier start arc for BASE.
  • Easier handling.
  • Similar flare power.
High Aspect Ratio Inlets

HIGH ASPECT RATIO INLETS

The new High-AR Inlet builds on the industry-changing innovation of our 3D inlet, with improved intake efficiency and less drag. The aerodynamic shape, finely tuned size, come from our performance R&D.

"New Seamless Leading Edge

NEW SEAMLESS LEADING EDGE*

Our proprietary leading edge Glide Skin now wraps more of the forward wing chord (*patent pending).

Integrated Profile Gripper

INTEGRATED PROFILE GRIPPER

Increases lifting surface without increasing the total surface area of the suit, while placing the pilot's hand in a more natural location. Result: Increased performance and comfort from the same amount of surface area – a “free” upgrade.

CUSTOM INTERNAL PRESSURE

All of our suits allow you to choose the amount of internal pressure in the arm wings. Choose from full pressure for maximum performance, or reduce it for easier maneuvering in acro / freestyle flight.

Airfoil Cross Section

AIRFOIL CROSS SECTION

Designed for Performance or Freestyle, the removable airfoil cross section adds glide and speed performance and increases agility and range in any suit that it is added to. More information on leading edge foam. More information on leading edge foam.

More Pockets

MORE POCKETS

More pockets! More snack-holes! Every Squirrel wingsuit gets an inside-arm pocket for sunglasses, a phone, your FlySight, or anything you want to hide from the rest of the world.

NEW NUTSACK

Don't be fooled by the shallow depth of this nutsack - it actually holds a lot of equipment. The new nutsack is a flexible hammock which allows more storage and also keeps items higher & closer to your CG.

LIGHT RIBS

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 new One-Zip system more durable and easier to use! It's cable free, and protects the zippers from being damaged by harness laterals. And it attaches to your rig in seconds. The adjustable lateral slot accommodates a range of harness types and sizes.

Evolv TRAX Rubber BASE Sole

The new TRAX Super Sticky BASE Sole has been developed in cooperation with Evolv, a leading climbing shoe manufacturer. The tread pattern is designed specifically for exit force traction, and the rubber is sticky in all conditions: wet, dry, warm, and cold. This mold is the only custom wingsuit sole ever created and is the highest performance option available.

Massive Leg Wing Pocket

The new leg wing pocket is the full width of the end cell, has zip closure, and is ideal for the stowage of hiking poles, ropes, and other equipment.

AIRTIGHT CONSTRUCTION

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.

Hook Knife

Hook Knife

Our sturdy double-blade hook knife fits into a secure pocket on the front of the leg. It's light, strong, and easy to grab.

MAGSNAPS

New magnet snaps require no pressing action to attach and securely lock together until they are intentionally lifted upwards to separate. Sometimes it's the little things...

Main Surfaces

Main Surfaces

Our main surface fabric is a 210D Rip-stop, with low stretch and an ideal rigidity-to-comfort ratio. Its balance of weight / durability, along with mechanical stability and tear strength, makes it the perfect mid-weight material for wingsuits.

Leading Edge Materials

Leading Edge Dacron

We offer two choices for wing surface Mylar reinforcement:

      1. Porcher Sport (white). Comes standard.
      2. Full GlideSkin. Increases glide performance and is more wrinkle-resistant. This option is recommended.

Internal Ribs

Internal Ribs

All ribs are constructed from lightweight sail cloth, chosen for its ideal stability-to-weight ratio.

Zippers

Super Sexy Zippers

SQRL wingsuits are constructed with the strongest and highest quality zippers available. Locking YKK 10C zips are used on the main body, harness-interface, and arm sections of every suit we make.
