It will compress super small... will go into a little bag like this: http://ecx.images-amazon.com/images/I/81cafzvpKFL._SY679_.jpg

My unofficial measurements are 3.5" diameter and a smidge (1/8 or less) over 10" high. I don't think your bag would close if it's 10" but the diameter should be fine

The bag may compact a little. It will still will be about 3 or 4inches thick. Great quality.

Going to depend on how small the bag will compress. I bought the orange one for a youth size north face mummy and it's big enough to hold a bigger bag.

Unfortunately, I have no idea. It presses down to be pretty compact. The bag with the sleeping bag looks designed to clip on or into a back pack.

It goes in a small bag which is it cinches up to probably the size of a small throw pillow

If you're using it just for the liner -- 6 strap compression stuff sack would be fine. Lying flat the compression bag would be approximately 18 x 23. Diameter is approximately 32" around bottom of bag. If you need one, let me know I have one in very good condition, which is not listed (I can list). The 9 strap is a tad longer & wider - 9 strap made for the entire USGI sleeping system, which is the bivy cover and the sleeping bag (I also have 9 strap).

I would recommend the small sack 7" X 16", 10L down to 3.3L, it would give you some flexibility.

I have used it for my son's boy scout mummy sleeping bag which is about 31" x 84"+/-. For my king size Coleman 20 degree bag (about 39" x 90"), I purchased VAS 23"X 183/4" COMPRESSION GEAR SACK - SLEEPING BAGS & GEAR which worked out really well. In addition, we backpack with external frame packs and being able to compress into a cylinder versus a ball strapped much easier to the frame

It would be a tight fit. It might would fit if you positioned it from bottom corner to top corner of the bag, that would give you a few more inches of room.

I'm not sure this will compress the direction you want. These are end cap compressions, not side compression. But for the diameter of most thermarests, I would think small would work. I use these for either my clothes for backpacking or my summer weight sleeping bag. I can compress the small size with my sleeping bag to a little more than softball size.

8 1/2 by 11 pages and smaller is all that will fit. The excellent padding limits the storage pocket on the back of the bag.

Around the 3-4 inch area. It will compress smaller when you lay on it of course.

My brother's zero degree bag fit in a medium sack but it did take quite a bit of effort to stuff it in. Therefore I would think large just to make things easier on yourself.

I actually sent mine back because it was just too big. I think it would compress down pretty thin though. It's not too rigid!

Its small and I don't even use mine. I've gave to my 7 yr old boy if that tells you what I think about this bag

The bag is too small. The 10-18, and the 10-18-55 will work but no room for the larger one
