Maxima Jacket Kit
Commercial cold weather jackets usually have a single layer of insulation, disguised in the specs as "1.8oz/60g". That's fine for fair weather hiking, but it just doesn't cut it when you're staring a prolonged stretch of 30 degree rain in the face. AYCE's Maxima lets you customize the insulation, plus it's packed with cold-stopping features: fully baffled zipper with Dacron no-snag strip, SnowStopper shock cord waist, and insulated cuff, collar & handwarmer pockets.

Minima Vest Kit
The Minima's streamlined construction and highly detailed instructions make it an ideal first synthetic insulated apparel kit. Plus it'll be a go-to piece you'll reach for both on the trail and for everyday around town use. Bulk up your loft under a shell, boost the rating of your sleeping bag, or ward off the cold on windy or chilly days- you name it. Check it out!
