The North Face

Thunder Micro Jacket - Men's

Freezing with a pair of crampons or skis under your feet is never fun. Get The North Face Men's Thunder Micro Jacket and never sacrifice warmth for space again. Its FlashDry technology at the underarms pushes your sweat away from you while you hike up the mountain and disperses it quickly for lightning-fast drying. When you get to the top, the 800-fill down insulation warms your torso, and this down is water-resistant so you don't have to worry about losing the warmth if it gets a bit damp. The nylon micro-ripstop shell breathes and resists abrasion so you can wear this ski-touring in winter and backpacking in early spring.

The Thunder Micro has an alpine fit to reduce bulk as much as possible without restricting your movement. It's so compressible that you can stuff it in its own pocket and clip it to your harness for easy access at the top. Two hand-warmer pockets have a lot of space, and you can even access them with a harness or pack on.
