OVERVIEW

The Men's Lykan Half Zip is the venting version of Houdini's 3D-knit active mid-layer. The zip collar is the point: open it to dump heat on climbs and intervals, close it against wind on descents and cooldowns — the pick when effort levels swing. The fabric is Airweb Knit, a Shima-Seiki Wholegarment construction using 100% recycled and recyclable Teijin yarn produced in Japan, with hems and collars knitted in rather than sewn on for fewer seams and zero-waste production.

DETAILS

Best for:

Stop-and-go trail runs and ski tours where output swings

Runners who regulate temperature at the collar rather than by shedding layers

Base or mid-layer duty under a shell or fleece
