Ridge Infinity Jacket 2.0
Helly Hansen
The Helly Hansen Ridge Infinity Jacket 2.0 is built for demanding freeriders and resort skiers who prefer the modular flexibility of an uninsulated shell. Designed to handle varying mountain conditions, this jacket acts as an external shield against moisture and high winds while leaving internal temperature regulation entirely up to your layering choices. It is geared toward active skiers who frequently drop into sidecountry terrain and generate significant body heat. At the heart of the Ridge Infinity 2.0 is Helly Hansen's proprietary Lifa Infinity membrane, a solvent-free technology bonded to a recycled face fabric that maintains high-end waterproof breathable standards. Testers point to its relaxed, articulated cut that easily accommodates insulated midlayers without feeling restrictive across the shoulders or chest. Weighing roughly 860 grams, the shell carries enough substance to shrug off heavy snow and tree branches while offering reliable wind blockage on exposed ridge lines. Because the shell carries zero built-in insulation, purchasing this jacket means committing to a dedicated layering system for colder midwinter days. It also sits on the heavier side for dedicated ski mountaineers who prioritize ultralight gear. For skiers who prioritize ruggedness, weather protection, and off-piste mobility, it remains one of the strongest technical hardshell contenders available. **Highlights** - Eco-conscious Lifa Infinity waterproof/breathable membrane technology - Relaxed freeride cut optimized for comfortable under-layering - Backpack-compatible high-volume chest pockets - Life Pocket insulated compartment to preserve phone battery life in the cold - Detachable stretch powder skirt with jacket-to-pant attachment **Watch-outs** - Zero thermal insulation requires disciplined layering underneath - Sits slightly heavy for long-distance backcountry missions - Relaxed cut may feel excessively baggy for slender frames

Alpha LifaLoft
Helly Hansen
The Helly Hansen Alpha LifaLoft is an insulated performance jacket targeted squarely at resort skiers who prioritize warmth, weather protection, and a tailored, athletic silhouette. Rather than feeling like a bulky winter parka, the Alpha blends technical four-way stretch fabric with low-bulk synthetic insulation. It suits skiers who spend full days on the mountain in freezing temperatures and want an all-in-one upper layer without extra fuss. Helly Hansen pairs its Helly Tech Professional waterproof membrane with 100 grams of Primaloft Black LifaLoft insulation throughout the garment. Third-party testing platforms frequently single out this jacket for its exceptional warmth-to-weight ratio, noting that the LifaLoft fibers trap air efficiently while maintaining a slim visual profile. The mechanical stretch of the outer shell allows dynamic movement through carving turns, while specialized venting channels help dump excess heat when temperatures climb toward freezing. The compromises lie in price and high-output breathability. At a premium MSRP, it represents an investment piece best suited to skiers who routinely encounter cold lift rides and damp resort conditions. While the vents do their job on the piste, the jacket is fundamentally too warm and specialized for backcountry touring, where sustained aerobic exertion quickly overwhelms insulated garments. **Highlights** - 100g Primaloft Black LifaLoft low-bulk synthetic insulation - Helly Tech Professional 4-way full stretch fabric for unhindered mobility - H2Flow mechanical venting system for temperature management - Life Pocket+ with aerogel insulation to extend electronics battery life - Detachable, helmet-compatible hood with high-visibility brim **Watch-outs** - High retail price point - Athletic cut leaves less room for thick under-layers - Far too warm for backcountry skin tracks or spring touring
