I purchased this pack after doing a lot of research and trying different packs at different expos. I ordered the Beartooth 80 just due to its size. I can fit tons of stuff in it but mainly wanted it for elk pack trips. The adjustability that Mystery Ranch gives you with there packs is amazing. The weight load is on your hips mainly and keeps all that weight off your shoulders unlike traditional packs or bags. I would recommend them to anyone and I will be buying a smaller version for quick trips in the mountains.
