I bought a Black Ovis Large/Deer set off Camofire a few months ago. They're my first set of synthetic bags...I've always used pillowcases or the stretchy cheesecloth ones in the past. From my inspection and handling at home, I think they will be awesome. They're ever bit as durable as a heavy pillowcase, and I have no concerns about hanging the bags by the drawcord. The reflective strips are a very appreciated feature for me. Mine are the old/shorter length ones from last year I guess. The whole kit weighs about 14.4 ounces, 12.? with just the five bags and the stuff sack. I left the drop cloth out because I use a heavier piece of plastic for my ground cloth and I'll use that if I want to. The stuff sack is less than half an ounce, and is stretchy enough to easily fit some zip ties, extra gloves, my game tags, Havalon, and some extra blades.
I'm leaving for my deer hunt in the morning, so hopefully I'll have some field experience to review them with by the end of October. I'm have no concerns after pulling/stretching/messing around with them at home.
Camofire ships super fast from what I've experienced with the couple last minute orders I placed in the last week. I've been getting stuff via cheap USPS in 2-3 days consistently.
