The sizes can be very deceiving. I usually wear large clothing however with the ability to adjust the torso and the shoulder straps I ordered a medium. The main concern with sizing was the length of the carrier and that is what has to be a focus when ordering size. The material was stiff at first but after just one week has loosened up and moulded well. This is a great carrier and I would highly recommend it to anyone! Another plus .... The price can't be beat, optics planet beat out the competition by $100 and even though it was on back order was here in two weeks.
Pros: great fit, the ability to adjust the torso and shoulder straps allows for an awesome fit.
Cons: material is a little stiff at first but after a few day it moulded to my body and my armor very well.
