My wife is a very cold sleeper and often has a difficult time “warming up”. She sleeps in a Marmot Helium sleeping bag EN rated 26* (women) and 15* (men) on an Exped Synmat (R 3.3). She also layers her large down jacket on top of her base layer. In general, she says that she has a hard time getting warm, but is fine once she finally warms up. At home she’ll often draw a hot bath just to “warm up”.
I’m the polar opposite and sleep extremely warm. I recently started using a 20* quilt so that I can better regulate my temperature and have finally started to sleep well. I may never go back to using a traditional bag.
On our latest trip, the overnight lows were in the high 30’s. After being cold the first night, she started sleeping with a warm water bottle. She said that this was a huge help and that the water bottle stayed warm almost the entire night. We always eat a hot meal with hot cocoa before bed. She’s also been cold on other trips, where the temperature was in the mid 40’s.
I don’t expect any of our trips to ever get below 20* and I’d be surprised if we ever go below freezing. I’ve thought about trying the following in an attempt to help her sleep warmer:
- Use a two-person quilt (EE Accomplice) or two-person bag (Feathered Friends Spoonbill)
- Get a warmer bag. (Something rated for 0* or lower)
- Layer an additional pad to increase R value (I don’t think this is the problem)
I’ve read several posts here about couples who have had good luck sharing body heat with a twin setup. My thought is that by sleeping together, I’ll be able to provide a better source of heat than she can alone. I’m not sure what temperature rating we’d get, and I’m afraid that I’ll burn up. I’m also nervous about how she’ll be impacted by drafts.
What would you do? Any suggestions on how I can help her sleep warmer?
If we did go with a twin quilt, what rating would you recommend? Would a zpacks quilt be better so that we could shift the down to her side?
Thanks,
Chris
