Sea to Summit quality
Great down sleeping bag, I saw it was Sea to Summit and had to get it, excellent warmth to weight/space ratio, tried it at home and feels very warm, I have yet to test it outside, the water is just starting to get cold so will give it a spin at the first opportunity. I like the color too.

Excellent bag and lightweight
This is a great bag. It works well down to about 10 degrees F and does work down to 0 F. I have begun using this bag as my main bag in the jeep in case I'm stuck out in the backcountry in the winter. Its comfortable and lightweight
