This is a fabulous item. Just look it up.

I purchased at an estate sale then found it had a cut in it. I contacted EXPED and they professionally repaired it. Note the repair ticket where it passed their 48 hour under water inspection. Wow!

This baby is rated for winter as it has a whopping 7 R-Value.

I have not blown it up. No need to. I have added a photo I found on the web for reference

Check it out in Boulder. Cash preferred.
