I am looking for a bargain sleeping bag. I dont have a bag right now and usually just sleep in my gear, a little crazy for winter camping in colorado. So I think that it might be a good idea to finally get a bag. I only have $100-130 to spend. So far I have been looking at the Marmot trestles bags.

Any suggestions on other options or if any one has experience with the trestles bags please let me know.

Thanks
