Summary:
The Arc’teryx Alpha SL Gore-Tex Pant for men is an extremely lightweight and packable pair of rain pants that also manage to be some of the most waterproof on the market. These parts are very durable for their lightness, and can last years, even with regular use, although the Gore-Tex will have to be re-treated with waterproofing spray eventually. These pants do not have pockets, and some users dislike the hook-clasp system on the waist, but most everyone agrees that these pants will keep you dry for a long time, making them worth the price.
