Hey there Downslave! Sorry I'm a little late to the party. That sleeping bag looks awesome. Thanks for posting a picture of it. I'm a giant fan of these type of bags and so glad we all found some one who custom makes them as I have one myself in blue and yellow.
I know my good friend bondagefreak isn't that big on these kind of bags. He takes lots of pride in binding his subs in his own well made bounds. (Which I completely understand cause I know his bounds are pretty much impossible to escape from)
As for me, I just LOVE that everything is included on these bags. The internal sleeves keeping your arms pinned to the sides, with the outside straps making moving around in the bag impossible, and my favorite (not sure if your bag has this Downslave) the "locking" zipper sliders so even if you're not strapped down you still can't get out of the bag. Combine everything with puffy down fill inside the bag compressing all around you, and you're trapped at the mercy of someone else. I tried my hardest to escape my bag but I wasn't going anywhere. Also love how snug the hood is and when zipped up and velcro, it's pretty hard to breath in there.
Anyways, sorry for rambling. Thanks again for sharing the photo Downslave. Hope you keep putting that bag to good use.
