3L Insulated Hardshell Jacket (2026)
Built for cold backcountry & alpine ski adventures. This 3L insulated hardshell jacket from our Polar Series delivers reliable waterproof and windproof protection with zone-specific 3M insulation for consistent warmth in frigid mountain conditions.
80g 3M Insulation
Premium 80GSM 3M insulation delivers stable, lightweight warmth. It retains heat efficiently without adding excessive weight, optimized for cold alpine skiing conditions.
Zone-Specific Thermal Insulation
Precision-engineered insulation layout uses 80GSM 3M insulation targeted at the back and torso sides, reinforcing warmth around your core heat zones. This tailored placement prevents cotton bulk build-up, preserves mobility and avoids trapped overheating during active skiing.
Waffle Fleece Lining
Crafted from premium, higher-cost raw materials, this waffle fleece lining delivers exceptional next-to-skin softness and traps body heat evenly, providing consistent, comfortable warmth throughout cold mountain days.
RECCO® Rescue Reflector
An integrated RECCO® reflector enables professional search-and-rescue teams to pinpoint your location using directional radar in backcountry or avalanche emergencies. Requires no batteries or setup, providing seamless, zero-maintenance peace of mind on the mountain.

Description
The insulated 3L hardshell ski jacket from our Polar Series. Engineered for alpine and backcountry freeriding in freezing conditions, this jacket pairs our proven 3L hardshell construction with body-mapped 3M™ Thinsulate™ Insulation to deliver maximum warmth without adding unnecessary bulk or restricting mobility.
Designed for severe sub-zero mountain environments. We strategically targeted insulation across the core torso and back to lock in body heat while keeping high-output movement zones flexible—ideal for long summit ascents and cold backcountry tours.
Fabric Performance (CNAS‑ILAC‑MRA Accredited Lab):
- Hydrostatic Resistance: >34,000 mmH₂O (JIS L1092:2009 Method B)
- Water Vapor Permeability: 14,300 g/m²/24h (Inverted cup method)
- Martindale Abrasion: >30,000 cycles
- Surface Water Repellency: Grade 4–5 (ISO 4920 spray test, initial finish)
Note on Performance: All figures represent brand-new, unwashed fabric ratings. DWR finish naturally degrades with wear and washing. Please note: While the outer 3L fabric achieves high breathability, built-in thermal insulation naturally lowers net moisture expulsion. This jacket is engineered primarily for cold-weather thermal protection.

Layering Guide
Streamlined 2-Layer Alpine System
Engineered as a high-performance all-in-one weather barrier. By integrating 3M™ Thinsulate™ thermal insulation directly into a 3-layer stormproof hardshell, our Polar Series jacket eliminates the need for bulky mid-layers. Simply pair it with a technical base layer for optimal warmth, breathability, and maximum mobility on the mountain.
Layer 1 – Technical Base Layer (Next-to-Skin)
A high-output moisture-wicking top. Pulls sweat away from skin to eliminate cold dampness and post-activity chill, maintaining a dry internal microclimate all day on snow.
Layer 2 – Our Polar Series 3L Insulated Hardshell
Your all-in-one weather barrier and thermal core. The 3-layer outer shell seals out snow, rain, and mountain wind, while body-mapped 3M™ Thinsulate™ insulation delivers targeted warmth in severe low-temperature environments.
