Fits just fine vertically in my Granite Gear packs (Nimbus Meridian and Vapor Trail) with room to spare on the sides; even managed to cram it horizontally in the bottom of an Osprey Ariel 65.

I'm surprised at how much trouble some people have opening theirs. I put the canister between my legs and squeeze while depressing the tabs with a finger and turning the lid with both hands. Works great. Much easier for me than having to remember a tool.

As for size, this thing is pretty amazing. It's really too big for the 2-3 night trips I've used it for so far (just holding food for me). I'm looking at getting a BV450 instead for that length of trip.

These are beautiful, well-made gloves as everyone says. I can verify that the size chart is quite accurate: my hand measures a 9 in length, but a 10 in perimeter; the finger length is perfect in a size 9, but I need a 10 to get an unrestricted palm fit. Unfortunately this means that the gloves don't quite fit my non-standard proportions. (It's still at least as good a fit as any other brand I've tried.) I'm still rating the gloves a full 5 stars since I cannot fault them for being exactly what they claim to be.

Took this and a garcia cache on a three day/two night outing with four people. It was a stretch holding all our food and smelly things though we weren't being very efficient about it.

The instructions were a bit confusing, but once I realized I could just use my finger pad instead of my fingernail to press the lid in, operating it became a non-problem. Haven't tried it with insulated gloves though; I could see that being an issue. Still, I prefer this over needing to carry a tool (coin) to open the lid lie the garcia.

Last but not least, I was pleased to discover the bv500 fit nicely into the bottom of my Ariel 65 sitting sideways.

Build quality is good. Nothing is wearing out prematurely (after 2 months).

As others have said, the fit is funny through the torso. I'm not the most 'athletic' in shape, but pretty skinny by american standards. I'd fit into the medium but it was a little tight across the stomach so I went with a large. I've got enough room to pull my hands into the sleeves now, and fits just a little lumpy.

It also washed nicely. I was worried about the fur getting broken down somehow but it still looks good as new.
