I have a Transpac II that I would like to sell. It is an XL, but I also have M/L straps for it. So, with those straps, I think it should fit someone who wears a size M, since you can tighten the waist as needed. I also have a Rec Wing for it. There are some extras, such as weight pockets, a flashlight holder, and a crotch strap. It shows some signs of use, but I would say it is in good condition. I could sell it all to you for $150 plus shipping from southern Virginia. Let me know if you are interested, and if you have any questions.
