Rab Alpine Pull-On Jacket - Men's - 2010 BCS

This jacket was a gift for my son in college. He likes the versatility to wear this as a wind shell or even as a light weight rain jacket for cool and drizzly days in the summer. Plus, it packs up fairly small, so you can carry it as a "just in case" jacket in a small pocket of your day pack or stuffed into itself in the hood or pocket.
But, it is cut too tight to pull over any winter layer like a fleece jacket or insulated vest. This pullover will only layer over a heavy long underwear top. The sleeves are long, which is fine, but the body is too short, so it will not cover the waist if you stretch your arms over your head ( like when climbing ). It needs another 2 to 3 inches in the chest for this size ( XL in USA, but XXL in Great Britain size chart ). And it needs at least another 3-4 inches in body length to cover your tail. If it were cut fuller and longer, I would buy one for myself.

Water resistance is better than I anticipated, even without any seam taping, and wind resistance is surprisingly good for how light and thin this piece is. Best advice- size up. It's snug in the chest and shoulders, and you'll definitely need a base layer if you're looking for any insulation. Do not expect this to serve as a lightweight replacement for your shell. It's a real niche piece of gear with limited range of appropriate uses.
