It's hard to find major fault within the Spine Jacket: it's lightweight, impressively breathable, and supremely waterproof - even in the worst of weathers. The cut in both the men's and the women's is fantastic, with superb freedom of movement, although watch out for those tight cuffs on the women's if you're used to wearing a large watch. When it comes to durability, it is undoubtedly a light weight jacket and its 13 denier face fabric isn't designed with sharp rocks in mind, so be warned if you're on more technical ground. That said, we've found it to cope well with extreme use, although perhaps this isn't all that surprising given its namesake is one of the most taxing races in the world!
