Hi Glenn,

I used a Haven 20 extensively last year and it's nice for a first effort. I found the temp rating a little optimistic and would like to see some improvements: uprate the down or add more for extra loft, enlarge the hood opening (or add a short zip) enough so anybody can enter or exit via that as an option to the bottom opening and allow arms and shoulders out on warm nights.

It's very roomy and comfortable and yes, a side sleeper will end facing inside the hood because you need to keep the bag aligned with the opening facing downward.

The shell fabric has good dwr but the lining sheds a lot of down, might need calendering.

Hope that helps a bit.

Cheers,
