I have an Orvis Vest/Pack. It is used but not very heavily. My son wore it for a year or so before I got him a normal vest. It has a tag inside that says S/M that may be a size tag.
Asking $15, I'll ship is via USPA Priority for the $5.00 cost, a total of $20. Would like a money order or cash/check. Can do Paypal but would rather not. I'll ship when the money shows up.
