PEAK PERFORMANCE DEBUTS THE LATEST ALPINE GORE-TEX 3L SHELL
02/October/2026
After 17 seasons of development, Peak Performance's Alpine GORE-TEX 3L shell returns as a purpose-built system for ski guides, mountain rescue teams, and serious off-piste skiers who demand uncompromising weather protection without sacrificing mobility. The 2026 iteration builds on a legacy of backcountry-proven performance, integrating GORE-TEX C-Knit technology, enhanced ventilation, and safety features that have made the Alpine line a staple among Scandinavian freeriders.
Weather Protection and Breathability
The Alpine jacket and pants are constructed using 3-layer GORE-TEX C-Knit fabric with an ePE (expanded polyethylene) membrane, delivering a waterproof rating of 28,000 mm and breathability of RET <13 m² Pa/W. This places the system firmly in the professional-grade category, comparable to other high-end backcountry shells from brands like Arc'teryx, Norrøna, and Mountain Hardwear.
GORE-TEX C-Knit backer technology represents a significant comfort upgrade over traditional 3L constructions. The circular-knit inner layer is softer against the skin, reduces fabric noise, and improves overall breathability by up to 15 percent while reducing weight by as much as 10 percent compared to previous-generation GORE-TEX products. For skiers transitioning between high-output ascents and exposed descents, this means better temperature regulation without the clammy feel common in older hardshells.
Both pieces are fully seam-sealed and feature YKK AquaGuard® zippers throughout, ensuring complete windproof and waterproof protection in storm conditions.

Mobility and Fit
A standout feature of the 2026 Alpine jacket is the GORE-TEX Stretch panel across the upper back and hood, designed to increase articulation during technical ascents and aggressive descents. This addresses a common limitation of traditional 3L shells, which can feel restrictive when reaching overhead or shouldering a pack.
The jacket uses a Regular fit with hip length, articulated sleeves, and a dropped hem for coverage during movement. Weight is competitive for a pro-level shell: 0.66 kg (1 lb 7.3 oz) for men and 0.58 kg for women. The pants weigh 0.55 kg (men) and 0.53 kg (women), making the full system approximately 1.2 kg—light enough for touring while maintaining the durability expected of guide-level gear.
Cordura reinforcement at the pant cuffs adds abrasion resistance in high-wear areas, while the jacket's 70D lightweight ripstop face fabric balances durability with packability.
Ventilation and Temperature Management
The Alpine system excels in adaptability across fluctuating activity levels. The jacket features zippered underarm vents for rapid heat dump during climbs, while the pants incorporate full-length side zippers that enable fast temperature adjustment without removing boots or layers. This is particularly valuable for ski guides and rescue personnel who transition between high-intensity movement and stationary positions in exposed terrain.
Both pieces integrate with Peak Performance's snap-in snow skirt system, allowing the jacket's detachable powder skirt to connect directly to the pants for complete snow sealing during deep turns or falls.
Safety and Guide-Specific Features
The Alpine line retains several heritage features originally developed for mountain guides and rescue teams. Most notably, the iconic radio pocket on the jacket's chest includes an antenna exit, enabling two-way communication without exposing equipment to the elements. While less critical for recreational skiers, this feature underscores the system's professional pedigree.
Both jacket and pants include integrated RECCO Rescue System reflectors, enhancing searchable safety in avalanche scenarios. The pants also feature snow gaiters with anti-slip elastic and loops for the snap-in skirt system, while the jacket includes a ski helmet–compatible hood with two-way adjustment (height and width), a laminated brim for visibility in storms, and Cohæsive™ cord-lock hardware for one-handed operation with gloves.
Additional details include elastic wrist gaiters with thumbholes, adjustable sleeve hems with Velcro straps, a goggle wiper, soft fleece-lined chin protection, and multiple pockets: hand, chest, internal, and the aforementioned radio pocket on the jacket; hand, leg, and back pockets on the pants.
Sustainability and Materials
Peak Performance has constructed the Alpine 3L system using recycled polyamide components in both the face and backer fabrics, contributing to responsible material use without compromising performance. The GORE-TEX ePE membrane is produced without intentionally added PFAS, aligning with industry-wide efforts to eliminate persistent "forever chemicals" from outdoor gear.
Who It's For
The Alpine GORE-TEX 3L shell is designed for:
Ski guides and mountain professionals who require reliable protection in extreme conditions
Freeride skiers spending full days in variable off-piste terrain
Backcountry tourers who prioritise breathability and mobility over insulation
Rescue personnel needing integrated safety features and communication compatibility
The system is less suited for resort skiers seeking insulated warmth or casual users who prioritise style over technical performance. The Regular fit runs trimmer than Peak Performance's Gravity line, favouring athletic builds and active layering systems.
ALPINE 3L: A SUMMARY
The Alpine Jacket and Pants use GORE-TEX ePE membrane technology and are made without intentionally added PFAS. Both products are built using recycled polyamide components, contributing to responsible material use and extended product life.
RECCO Rescue System reflectors are integrated into the pants, enhancing searchable safety in the event of an emergency.
The jacket also features a radio pocket on the chest, historically used by mountain guides for communication during rescue operations.
