hey guys hope someone can help me out....my torso measurment is 23 and im having trouble finding a pack that size....the closest i can find is up to 22....and there usually bigger packs in the 90L range....anyone know about a pack that is in that size(large volume doesnt really make any diffrence to me just wont compress anything) or would a 21 or 22 torso measurment work......i do get lower back pain from time to time and i was hoping to minimize this but if i cant then oh well ill just have to endure it
