It has seen a lot of rain and moisture from paddling. Noticeable moisture around the corners and some light dew builds if it's warm in the morning. Vestibules are enough for your pack and some shoes--you could easily cook on a small stove too. The size if perfect when deployed--quick skeleton set-up, room for 2 or just 1 with all your gear inside. It fits wonderfully in my 60 pack and I think it's great for casual and committed adventurers.
