My wife quickly jumped in the Helium once we got "camp" set up. Her bag is next to it, a 15* SD women's down bag. She loves hers, but says mine is more comfortable...

When I got this bag I was contemplating the WM Antelope and the Kodiak, but I figured 15* would be enough for me for now. I was not disappointed either. The bag is beautiful. Flawless stitching, great design and quality materials. This bag is super comfy and plenty wide for me. I have used the Helium down to temperatures in the middle teens with a wind chill of 0 or less (according to the Weather Chanel). I got a little cool feeling close to early morning, but that may be due to the sleeping pad I was using. (The NeoAir with a Gossamer Gear 1/8" ThinLight pad which is not intended for these temps.) In the end, I am completely happy with this bag and do not hesitate to recommend it to anyone.
