Burton Men's [ak]® Freebird GORE‑TEX 3L Stretch Bib Pants Soft Sage

The Burton Men’s [ak] Freebird GORE-TEX 3L Stretch Bib Pants set the standard for backcountry-ready outerwear. Built to handle deep snow, high output climbs, and demanding descents, these bibs deliver the perfect balance of performance, protection, and mobility. The Soft Sage colorway adds a refined, modern tone to Burton’s most technical shell design.

Constructed from GORE-TEX 3-Layer Recycled Polyester 75D Plain Weave, the Freebird Bibs are fully waterproof, windproof, and breathable, GUARANTEED TO KEEP YOU DRY™ in the harshest alpine environments. The three-layer construction keeps weight to a minimum while maintaining exceptional durability and packability, ideal for splitboarding, hiking, or deep resort days.

The stretch fabrication and articulated patterning allow unrestricted movement whether you’re skinning up, bootpacking, or strapping in. Details like crossflow venting, exterior thigh vents, and mesh-lined continuous inner thigh vents make temperature control easy, keeping you cool during climbs and warm on descents.

Every feature is rider-driven: adjustable suspenders, crotch gusset, and triple-needle reinforced stitching maximize comfort and longevity. The anti-scuff cuffs and bungee cuff elevator extend durability in rough terrain.

Storage is fully dialed for backcountry utility, with zippered chest, hand-warmer, cargo, and back pockets, plus an internal media pocket with port and a dedicated beacon loop in the right pocket.

Made with bluesign® approved materials and a PFAS-free membrane, these bibs represent Burton’s most eco-conscious high-performance design to date. Backed by Burton’s lifetime warranty, the [ak] Freebird Bibs are built to ride anywhere, from stormy alpine peaks to spring corn tours.

The Soft Sage colorway brings a natural, understated aesthetic that pairs effortlessly with the rest of the [ak] collection, combining top-tier performance with timeless style.
