## Questions & Answers

**Q: I'm looking for one that would be good for packing clothes into.  This one is deep but not that big around at the base.  Is there a better one??**
A: This works for clothes, but the original works better because it is easier to compress and keep compressed.

The original one is one of the best pieces of camping gear ever designed. This version has straps that are too soft and get twisted too easily, and do not hold firmly enough. They may stay compressed inside your pack, but if you hang the bag on the outside, by the straps, they will loosen as you walk.

Also beware that a medium ultrasil event compression is smaller than a medium original.

**Q: How many liters is the xsmall?**
A: 3.3L

**Q: I have a kelty tuck 22 that compresses pretty well, but i have no idea what size sack to get for it.  Any ideas?**
A: take the bag to an outdoor store like REI and stuff it into a bag to figure out what size you need

**Q: I have a Kelly cosmic down 20degree. What size 10 or 14?**
A: Not exactly sure. But I just got the biggest one I could. I have four of them and really like them. The weight between sizes is very little. They compress very well and it's all ways nice to have a little extra room if needef. So if it was me I'd just go with the 20. I've done as little as 4pr socks and underwear with a jacket and it compressed fine. The biggest load was a -20 bag but was a very tight fit. However I would not use this item on the outside side of my pack for it is very thin. Hope this helps
