what size do you have?
Sorry for the belated reply. I have size small I am 5' 2" Just make sure the closure at waist doesn't sit above your hip bone or it will cut into you.
Correction. I said it was an XS, I have looked again and found it to be a size Small. My 20 year old daughter uses the pack and loves it. It fits her frame very well. She has camped in Labrador Canada and throughout North Carolina with the Jade and has found it easy to carry and easy to access. She weighs about 115 and routinely carries 50 lbs in the pack. If you are going to travel by plane to your hiking/camping destination I would suggest putting it inside a duffle bag to protect the fabric during flight.
XS. Purchased for a 5' 6", 115 lb woman.
I chose the 60 liter for my 7 month trip around the world and it was perfect.
The waist belt gave lots of support and it was a comfortable pack for relatively long periods of walking. The front and top openings made it pretty easy to find things, and the pack held up well to be thrown off and on over 24 flights, numerous buses, boats, rickshaws, taxis, etc, etc.
I bought a small. I'm five foot eight and 150lbs and even proportion of upper and lower body. it's perfect though it's a women's pack it's still standard sizing.
we bought a 60 for my college student. She is an adventure ed major and needed it for weekend trecks. Great for that but next semester she is thinking of getting a 70.
