The Cocoon line of jackets and pants is manufactured by Bozeman Mountain Works, a now defunct boutique manufacturer of ultralight backpacking gear. Their UL 60 Vest, shown here, uses Polarguard Delta insulation, a lightweight synthetic material that along with Primaloft, became popular last year with mainstream manufacturers like the North Face.

I frequently use this vest when hiking or snowshoeing in sub-30 degree weather layered over a Patagonia Capilene 3 jersey and under a Gore-tex shell. The lack of sleeves is not an issue under these circumstances because I’m generating plenty of heat.

I’ve also used this vest as an insulating layer under a storm shell in cold rainy conditions. I originally purchased it to replace a Montbell down vest because I was concerned that the insulating properties of a down garment would degrade when my base layer became saturated in very humid, but chilly weather. The weight, cost, and perceived warmth differences between these garments is negligible and although I still adore my Montbell down vest, I prefer my Cocoon in high consequence, wet environments.

  1. I wanted to order one of these and was not sure of size.

    I am 5'8", 160#.

    How big are you and what size fit you?

    Thanks,

  2. I wish I could tell you – I cut the tag off long ago to save weight. I suggest you call the manufacturer and ask about sizing. If I had to guess, I probably ordered a large.
