> Is this jacket too lightweight as a waterproof layer for summer Alps trips? Thinking it will be used to throw on in afternoon storms when walking into huts etc...
That's pretty much exactly what I've been intending to buy one for, for months.
That, plus U.K. cragging in uncertain weather, and clipping to the back of ones harness for topping out onto cold windy belays.
The mountain jacket version is fantastic looking and will be my choice. I figure the much better hood and addition of chest pockets is worth the tiny extra pack size and weight. They all pack down to an astoundingly small size - my main concern/requirement above all others, including weight.
I mean, a breathable fully waterproof hooded jacket for the size and weight penalty of an apple?! You can't beat that. It'll never be noticed, whether it's stuffed in a pocket, pack, or back of one's harness.
Regarding being too lightweight? I don't think I'd worry about that too much, especially if you don't intend to use it as a main waterproof and just for when you get caught out. It seems surprisingly robust for the weight of it.
So yeah, definitely a +1 from me on your idea if that helps?
Regards,
Jonny.
