I'm 5'8" about 130lbs and ordered a medium, if that helps. I think it fits well, not tight at all.
I like this jacket a lot. I have longer arms and the seam length is perfect. Also, I purchased the white color and all my guy friends thought i was crazy, thinking i'd get it dirty in one go...wrong; it washes beautifully.
I bought this pack for my mother who has cancer. She can't get out of bed very often and it's imperative that she stay hydrated. So, I bought this pack and slung it to her bed post filled with ice water - genius.
i love this tent. it's fast, easy, and easily and readily accommodates my large dog and myself and my pack.
i've only been rained on once and i haven't yet camped in the snow, but so far, it's a great little tent.
i also love that when you don't have the rain fly over the top, you can star gaze all night long! also, i swear i had a bear come nuzzle me one night and he thought it was pretty cozy too.
