Got one of these in today, doing a trial run this evening whitetail hunting. Had gotten tired of how tough it was to constantly remove and then re-insert my binos in my AGC when sitting in a stand. I'm thinking I'll keep the AGC for out west where I'll be standing when I remove them or remove them for long periods to glass on a tripod and also offer the more protection from dust, but use the Marsupial for stand hunting here in the East where I can just leave it open and take the binos in and out easily and I don't have a need to have a bunch of little gear stuffed in it.
Follow-up - the Marsupial is an excellent design IMO. Perfect for treestand hunting so you can sit there with binos and rangefinder easily accessible. I also got a the zippered ouch and stuffed all the crap I had in my AGC in there, so in theory it would also work my style of western hunting. Only hold up is how dusty it is in CO and the open design of the Marsupial. Thinking I could run my tether strap through my eyepiece covers and be fine in that regard when traveling between glassing spots though.
