Built For
Alpine Touring
10° – 30°F
Cold skin-track ascents and sub-freezing descents where a midweight crew would soak through on the climb and chill on the way down. The heavyweight Intraknit™ insulation retains warmth under a shell when static, and the body-mapped ventilation dumps heat on the skin-track without breaking thermal continuity at the core.
Ice Climbing
0° – 25°F
Long static belay sessions in bitter cold where a lighter crew would lose core warmth, with high-output swinging bursts where breathability matters. The Merino Sport yarn’s polyester core keeps the fabric lofted when wet from ice and breath, and the heavyweight knit holds the heat through the slow minutes between pitches.
Lift-Served Skiing
15° – 35°F
Full chairlift days at the resort when the wind chill is the limiting factor. The heavyweight 3D-knit insulates under a shell on the chair and on cold lift rides; gender-specific body-mapped ventilation across the upper back and side ribcage dumps heat on the groomers without breaking core warmth.
Winter Mountaineering
Sub-Freezing
Multi-pitch winter routes and hut-to-hut trips where the temperature stays well below freezing all day. Heavyweight 3D-knit insulation layers cleanly under a hardshell and a belay parka; the Merino Sport yarn’s abrasion resistance stands up to pack strap wear on long approaches.
Layer Over It
Pair It With A Bottom
The Intraknit Thermal Crew is the upper half of a complete deep-cold Intraknit base layer system. Pair it with the matching Women’s Intraknit™ Thermal Bottom for a full-body heavyweight 3D-knit system, or mix with a Smartloft bottom for the warmest possible foundation.
- Women’s Intraknit™ Thermal Bottom matched heavyweight system
- Women’s Smartloft™ bottom insulated foundation option
- Women’s Classic Thermal Merino bottom warmer-on-the-legs option
- Women’s Hike PhD™ crew sock full-day cold-weather rotation pair
Layer Over It
Top It With A Mid & Shell
For full weather protection on the coldest days, layer a mid-insulation piece and a hardshell over the Intraknit Thermal Crew. The slim base-layer fit doesn’t bunch under a puffy or a shell; the heavyweight 3D-knit holds warmth against a belay parka’s compressible insulation.
- Smartloft™ vest or jacket core warmth on static belays
- Hardshell ski jacket wind and waterproof outer layer
- Women’s Hike Light jacket active cold-weather mid-layer
- Belay parka static-insulation outer for sub-zero stops
