Mountain Hardwear - Bishop Pass 15

First - are you positive you want to zip together with your partner? I did your same plan \~15 years ago. Got 2 bags and zipped them together. It was cute. At first. Then we soon became cramped / cold. We almost always preferred to be in our own bags vs. zipped together. After the novelty of zipping together wore off - it really wasn't useful. Just saying... don't spend the extra money / effort or limit your options for this feature if you don't really need it. If you still want the zip together bags - you are looking for sleeping bags that have 'left' and 'right' zippers. Buy one left and one right. At 15F nights - you want a 5F or 0F rated sleeping bag. Or a 15F bag plus a liner for the colder nights. Are you sure you want a traditional mummy bag? I personally prefer down quilts. They pack smaller and are more comfortable than my mummy bag. They also work well when 2 people are together. Snuggle under the blankets, but then go into your own cocoon for the night time. **What is your budget?** It looks like Mountain Hardware does mens zippers on left and womens zippers on the right. * [https://www.rei.com/product/235362/mountain-hardwear-bishop-pass-15-sleeping-bag-womens](https://www.rei.com/product/235362/mountain-hardwear-bishop-pass-15-sleeping-bag-womens) * [https://www.rei.com/product/235363/mountain-hardwear-bishop-pass-15-sleeping-bag](https://www.rei.com/product/235363/mountain-hardwear-bishop-pass-15-sleeping-bag) Nemo does the same: * [https://www.rei.com/product/228439/nemo-disco-15-endless-promise-down-sleeping-bag-womens](https://www.rei.com/product/228439/nemo-disco-15-endless-promise-down-sleeping-bag-womens) * [https://www.rei.com/product/251886/nemo-disco-15-endless-promise-down-sleeping-bag-mens](https://www.rei.com/product/251886/nemo-disco-15-endless-promise-down-sleeping-bag-mens) This is a unique option too: * [https://www.rei.com/product/231206/sea-to-summit-ascent-15f-sleeping-bag](https://www.rei.com/product/231206/sea-to-summit-ascent-15f-sleeping-bag) The North Face Cat's Meow was the one I had with L/R zips. But it looks like they took that feature away. I was also going to recommend the Kelty Cosmic Down as a cheap/budget option - but they also look to only sell right zip bags.

My current down mummy one from Mountain Hardwear that I got for a crazy deal (<$90). There are zippers on both sides and the toe area. I move a lot in my sleep, and the slightly wider area up top makes it easier. (It's wide enough for my arms to go to my shoulder area, even zipped up.) It's a huge step up from my previous one, a cheap synthetic mummy.

Mountain Hardware has a couple bags that are compatible, my wife and I use them. They are a little bulkier, but affordable. You could also look at something like the Zenbivy Double bed.

I have the Mountain Hardwear and love it. My kid has a North Face Inferno and loves it… and I worry less about water damage. I trust OutdoorGearLab.com for reviews. 

It's really a personal choice. I would suggest you try the MH sleeping bag. It's a free way to test a type of sleeping bag. Worst case, you buy another one later. I personally use down sleeping bags because they are lighter and compress better. But they are more expensive and take a lot longer to dry if it gets wet.
