I'm in an endless search for a down summer bag. I think I've narrowed it down to the WM Summerlite or a Jacks R Better No Sniveler quilt. I've tried and I'm pretty sure I've ruled out the Montbell Spiral Down #3 (only 2/3 zipper, I want full for venting).
My camping will be done this year in the Sierra (often at 8500'+) from mid-May till the snow sticks in fall. Also NorCal coastal camping in the winter. So I'm looking for something that will cover 30* up to 50*. And if it gets down to 20, I'll be fine using a Montbell Down Inner Parka I'll be carrying as extra insulation.
I am intrigued by the idea of a quilt. The price is right for the Jacks R Better (compared to a Summerlite) and they get good reviews here. Price is not the driving concern, though, as I'm looking for something I will be happy with for many years down the road. Value is the operative word.
It seems like a No Sniveler would be warmer for about the same weight than the Summerlite, while providing more venting options. I worry about getting to warm in the summer. I sleep warm. I thought I could make a 15* Marmot bag my all-arounder last summer and suffered for it. Though the Summerlite could be used unzipped as a quilt, while having the option of zipping for sealing in the warmth.
When I sleep I sleep on my side and periodically flip from one side to the other. I'm worried that with a quilt, every time I flip, I'll be letting drafts in. Having not used a quilt before, will it even provide adequate coverage to begin with for someone sleeping on his side? I sleeping in a tent (TT Rainbow) right now, but hope to move to a poncho tarp or something similar by next summer.
Thanks for helping me decide if a quilt is right for me.
