Quest Women’s Wide Synthetic Mummy Sleeping Bag

Just bought the ember quilt for summer camping Might get the disco 15 when it gets colder

At REI? Probably just the sea to Summit. Cottage brands just do a better job overall. Here's a good start, but there are tons of other options. https://www.garagegrowngear.com/collections/quilts-sleeping-bags?srsltid=AfmBOop9T_mFgmquiOSKZQgg1443MbZ_HlewD5AHWCbOT52ZRMPPJVRi

Knowing Kathmandu quality, this is likely as good as it gets with that bag. I wouldn't trust their temperature ratings. If possible, return it and buy a Sea to Summit or Mont or other brand sleeping bag. Sorry.

Never used a berghaus mate, snugpak is good for the price but I’ve upgraded to a sea to summit bag and a mountain equipment bag and can’t recommend either of them enough!

Quilts can get drafts, but then also sleeping bags compress and lose loft as you shift and expose the compressed side. About even in my experience. Sizing, quality of pad straps, or user error are all possibilities if you've had better luck with a bag over the quilt. Also, audio books with a sleep mask headset and ear plugs. Give a pillow a try as well. I use the better sea to summit version and it helped my sleep quality a lot.
