I just returned from a Kodiak Island blacktail hunt. This was my first field use of this pack and I found it perfect for use as a day pack and very effective in keeping my gear dry and easily accessible. Plenty of room everything I needed to carry in the field. While descending a moderate slope I slipped in the mud and in order to protect my rifle (I was carrying it by hand not in the pack sling) I left myself fall on to my back. Embarrassing but impressed how well the pack protected my gear from damage, kept everything dry, and how easy it was to clean up back at camp. A great product when used as designed and great when circumstances force off spec use!
