REI Radiant +10

It took me many different buys and returns at REI to find a bag I'm happy with. It fits large people well, I'm 6'1 and 250 lbs and it's not tight at all. It's true to its rating of 10 degrees, with mid weight thermals and socks, I was warm in 12 degrees. This hasn't been true with many other bags (even zero bags). A little on the heavier side, but what's 3-5 ounces if it's reliable and true to its rating.

Also for a regular price of $229 it's really affordable. I personally don't notice a temp rating difference between my old Marmot Colour ($449) 0 degree and this bag. Don't be fooled by its low price, knowing what I know now, I would probably buy it again if it was $100 more.

This is a great bag and on sale a fantastic value. It is not an ultra-lite bag but it is only ounces away from being one. Since it is not an ultra-lite it has benefits that are important to me.

It is made with heavier material and doesn't leak much down. It is roomier (bigger) and the material doesn't feel fragile. It also has been treated with DWR so water beads off. It packs small too.

Don't get caught up in high tech ultra-lite bags. They only offer a few ounces of savings at the expense of thinner material and tighter fit. This bag feels durable. Oh, it is plenty warm too...
