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.

Jeffery Chamberlain
Great pants

Was skeptical at first, most of these pants don’t fit me well, but these are great. I’m a 32 size waits and a 36 for my legs and such

Michael Howard
Perfect multi-purpose pants

Ideal pants for hiking, camping and traveling and comfortable enough to lounge around in. The only minor issue was that the drawstring came out after the first wash and was a pain to rethread, so consider tying it down before washing.

Best casual pants Ever!

Tested this out in Sierra Nevadas over memorial weekend. Temps 35-75°F. 5-15 mph winds.

These are incredibly comfortable. They seem strong and durable. It is soft and nice. It is stylish and relaxing. The utility of this is great. You can use as a jogger, or comfy walking the dogs or lazy days at home. I tried wearing baselayers under it. It works with certain base layers. Do not wear boot socks with this, because you may not be able to pull up your socks, with these tapered leg. It was too tight to get my socks up under. Now, with shorter socks or flip flops, it’s awesome. The pants really feel durable. Did I mention that? How can I have so many attributes that I love in one pair of pants?

The loop in the pocket is awesome. I attached my keys via carabiner. The small hidden pocket zipped up, inside the pocket, is clutch and awesome as well.

Never was an athleisure type. But these pants made me a believer. I want to buy More of these. Give us a few more colors to choose from, please. Also, Beyond, consider making these into shorts.

Beyond delivers again

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