I am 6'4" and want to get a double sleeping bag to share with my wife but the Big Agnes and Nemo bags I have looked at only support up to 6'2" (BA) and 6' (Nemo). Anyone know of a good solution? I'd prefer not to have to scrunch up as I have in some past sleeping bags.
Not the cheapest solution but you can buy two of the Nemo MEZZO LOFT™ LUXURY 30 SYNTHETIC SLEEPING Bags and zip them together. They show them fitting up to 6'8" and would be a couple of inches wider than the double bag. This also means you would have to buy two pads to slip in to them.
I ended up settling on the Big Agnes Cabin Creek. I was able to try it out before I bought it. Unlike mummy bags, length does t matter so much because there is so much lateral leg room. It seems to work very nicely and I am looking forward to trying it out for real this weekend.
I am 6'7" and have had a hard time finding a bag. I finally found a lightweight down mummy bag for bike travel and I guard it with my life, as I don't know that I would be able to find another one. For vehicle travel, I use a Caribou Mountaineering bag. I don't remember the model but it zips to a Caribou coupler that holds two Therma-rest camp rest pads. We have been using it for quite a few years and it has worked great. It basically makes into a king size bed, yet breaks down to a small bundle when stored. When travelling, we keep the bag and coupler zipped together and just fold it into a stuff sack and the pads go into their stuff sacks. Not even sure Caribou still sells my set up but if they do, I would certainly recommend looking into it.
The Wiggy outfit seems like a good alternative if the above is no longer available. In fact I bookmarked the site just in case. Good luck in your search and let us know what you find.
