SYSTEM LAYER GUIDE ?

Beyond System Layer 4

L4 - WIND PROTECTION

Ultralightweight, Highly Flexible, Treated for Comfort, Designed for Layering

Performance Fit

Low-profile design with an elastic waistband and tapered cuffs improves mobility and ease of layering.

Ultrapackable

Ultralightweight softshell and a streamlined fit combine to ensure easy stowing when not in use.

Double-Treated Fabric

Clear outer shell coating softens hand feel, and a DWR finish provides weather-resistant protection.

Multi-Season Versatility

The Men’s Avid Ultralight K4 Pant is a streamlined alternative to the Ventum Ultralight K4 Pant, designed for active, multi-season use and with increased ease of layering under additional protection. The trim, tapered profile and ultralightweight fabric ensure easy mobility and layering, and wind-resistant protection wards off chilling gusts while retaining warmth generated from activity.

Built for Versatility

Ultralightweight, quick-drying fabric with 4-way stretch combines with articulated knees to provide versatile performance as both a layer and a standalone jogger. A dry clear coating offers a softer hand feel, and a hidden passport pocket and key clip add convenience to everyday use and adventuring alike.

The Avid Ultralight K4 Pant is crafted with bluesign®-certified textiles—verified for ecological safety at every step of manufacturing—and is certified STANDARD 100 by OEKO-TEX® as free from harmful levels of more than 100 substances.

Bulk-Free Profile

Low-profile construction with tapered cuffs and an elastic waistband delivers a trim fit, allowing comfortable layering beneath additional protection without bulk or bunching up. Combined with air-sealing softshell performance, the Avid is an ideal midlayer for extreme cold environments.

Air-Sealing Softshell

The wind-resistant softshell seals out chilling gusts while retaining warmth built up from active use, ideal for active use in cold to temperate weather or as a midlayer in extreme cold environments. A durable water-repellent (DWR) finish helps light precipitation bead up and roll off.

Love the K4 pant

I am truly impressed with the quality and fit of these pants. So far I've worn them for road trips to rock climbing and plan to get more pairs! I'm 6`3" / 170 lbs and the medium with extra length fits perfect.

Comfortable and Good Looking

We are living in our camper for a couple of months while we relocate. I’ve been looking for something comfortable that I can wear many (!) days in a row and still look presentable. Made a new friend who had these pants and ordered two pair. They fit great and my wife really likes how they look. One criticism is that the black looks dirty the first day. I’m 6’0” and 155#, typically wear 33x34. I’m very happy with medium/long.

Fits well

Fit well and good at holding in my fat. Not too tight around the thighs, which is what I mostly run into even with jeans. A little tight around the ankles if I want to pull them up around my calf area to put on socks.
