Beyond System Layer 4


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.


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 L4 Pant is a streamlined alternative to the Ventum Ultralight L4 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 L4 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.

The pants are awesome. I will be buying another pair in different color.

Matt Laird
Best Pant Ever

At 6’4” I can never find good activewear. I’m now ordering my 3rd pair.

Matthew Kowalsky
Comfortable and sporty

My go to pant for weekend. Will get buying another pair!

Justin Carr
Awesome product

Lightweight, good fit, highly wind resistant, and comfortable…I bought these pants for coaching soccer in Wyoming. Spring time in Wyoming is usually rainy or snowy and always windy. These pants are perfect. I now plan on taking them to Alaska when I head there this summer to commercial fish,

Fantastic pants.

I am 6’1” and about 205 lbs with a long torso. I generally wear 38/30 in jeans due to my athletically large rump. This gives the backside room but the waist is a little loose.
A large regular in these pants was perfect. Not loose in the waist at all and plenty of room for the caboose. I would say they run shorter than expected. People of normal proportions may want the long if you generally wear a 32” inseam.

They look good enough for anything but dress pants. They are comfortable as sweatpants but much more weather resistant. Pocketing is good and ample. Rear pockets haven’t been super useful but I haven’t found a use for them yet.

Great at deflecting wind. DWR was tested by spilling water on myself while driving. It all ran off and beaded up. They are only one wash in so durability will need time to tell, but they seem durable enough with adequate abrasion resistance.

These layer nicely under insulation due to the tapered legs. I didn’t think they would be as comfortable as they were in this configuration, but I didn’t even notice them. I forgot I had them on until I took the top layer off.

I bought a second pair the first week I had them. Wish they came in a brown/ khaki color.
