futilitaria 1.0The Mountain Hardwear Lamina -20 is an option.
I have this bag. It is extremely warm. I use it if the temp is under 20F.
miro-tz 0.2I use a Mountain Hardwear Lamina Spark bag for this weather when sleeping without a tent. These are relatively light and not too expensive.
ckyhnitz 0.1My 11 year old 15 degree Mountain Hardware Synthetic mummy is as reliable as it gets, I've used it down to 22 degrees with a windchill in the teens and was comfortable. I trust it with my life. It's not even that heavy, right at 3lbs... only problem is that it's bulky. 12L stuff sack. I went with down for my hammock quilts, but if I have to sleep on the ground and worry about water intrusion or tent condensation, I'm using the MHW.
Miperso 0.0It'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.
