- Columbia's award-winning Peak 2 Peak shell is a serious workhorse that will keep you completely waterproof and dry, while at the same time allowing your body to breathe. It features their cutting edge Omni-Dry fabric, a leading waterproofbreathable technology. Great in wind, rain, and all sorts of temperatures, we've found the Peak 2 Peak to be a go-to jacket for almost every backpacking and camping trip we've recently been on.
