I have a small for a 32 degree down bag and a XL for a 15 synthetic. Both compress the bags as small as possible. Whatever few ounces these way are made up by having more pack space and thus less need for a bigger and heavier bag. I've beaten mine up good and sat on them and they are solid. I also stuff these with clothes and use as a pillow when backpacking with a fleece pillow case over it. Going to try an eVent model with my new down bag but these are great.

The XS should work fine for that.

Hmm... I don't think that would fit. Even the small might be kinda hard.

It's a tight fit in the small--the drawstring will barely close. Go for the medium.

The XS & Small sizes are great for just about anything that would be loose in your hiking backpack. I use them for extra socks/clothes/etc...compresses way down, makes way more space in the pack & lets you put the weight of all your clothes in one confined spot. 2 thumbs up.

I have the Sea to Summit eVent compression sack
(http://www.backcountry.com/sea-to-summit-event-compression-dry-sack), size small 10L, and my Arroyo regular fits in there with about 5" room left in the sack, definitely enough to fit the long Arroyo too. The regular should also fit fine in the XS, or if you want to play it safe, just go with 2 smalls.

Picture is the regular Arroyo inside the small seaToSummit eVent.

This is a great compression sac that is easy to use. I use a small for my 20 degree down sleeping bag and it compresses down to about 7 x 8in. the only complaint is that its not water proof. A great buy!

Because of the Silicone coating, they're water resistant, if you want waterproof- usually stuff sack aren't the first choice. What you might be looking for is a dry bag. Sea to Summit makes a great one called the eVac dry sack- amazing.

Or the eVent which is compressible.
