On fresh mornings when a tee won’t cut it, the Sonic Hoody is the only layer you need. With a close-fitting wrap-style hood and excellent articulation, this lightweight, technical baselayer adapts to a range of activities where you need a little more protection but it’s too warm for a midlayer. Breathable Motiv™ Aero fabric with bulk yarn technology responds to your output, effectively wicking away sweat and keeping you dry and comfortable on your fast hikes, mountain runs, and demanding ascents.
