What size would fit an Osprey Atmos 50 pack?
the medium or large of this pack cover will fit your atmos 50. but, so will the medium Osprey UL Rain Cover for a couple dollars less.
Adam. Hey, I just wanted to comment on the price difference between the two that Jason brings up. Not that two ounces matter that much (every ounce counts right?) but the Hardwear rain cover is a couple ounces lighter depending on the size. We use a 25D Hollow-Core Nylon that is ridiculously light and extremely durable for its weight and this is the main reason for the price difference. Cheers!
