Arc'teryx Alpha SL Jacket - Men's

If you're looking for a minimalist, very light rain jacket that will keep you extremely dry, then look no further. With the entire body made of Gore-Tex Paclite & the only frills being pitzips (waterproof zippers, so no flaps to add weight), and 2 hand pockets (also waterproof zippers), this jacket is incredibly light. However, unlike other lightweight jackets I've had in the past, this one really stands up to normal wear without realling showing it and without sacrificing useful features. For instance, the pockets aren't lined with cheap mesh, but instead are simply an additional layer of Gore-Tex Paclite layered over the body, allowing me to leave the pockets open without getting cold (although there is the downside that they can't be used for venting). This also means that if I do accidentally leave the pockets open in a rainstorm, that I still stay completely dry. The only downside I found was that when wearing the hood without a helmet, the hood requires a lot of cinching down, which creates very long lengths of cord on the back of the hood (where the hood volume is adjusted), which can flop around and hit you in the head in heavy winds. Also, it should be noted that the zippers are a little stiff when first used, but gradually become easier to use with use.

Seemingly impenetrable to rain, I wouldn't test it too much to abrasion though. If you're going to get Pac-lite, or just can't afford Pro, Arcteryx is the only brand to trust I think. Medium fits with loads of movement but snug enough to still be comfortable at speed on the planks (I'm 5'11" 160lbs). Why alpha you say? Its a bit longer and has a bigger hood for helmets. Otherwise identical to Beta.

I think they must have read my review of the last version of this jacket they put out. It now has two waterproof hand pockets on it. This is very packable, and light and has pit zips for venting. Will keep you dry in a downpour. You will need to layer if you are looking for warmth, this is only Gore-Tex Paclite.
