Love Haglofs Hypna down Sleeping bags!

LOVE this sleeping bag - extremely well constructed with a differential cut (inner layer is smaller that outer layer to allow down to fluff) and filled with quality goose down (90/10 - NOT from live plucked geese). I also love that Haglofs is an environmental friendly Swedish company. The bag lofts like crazy to keep you warm with no COLD spots (had problems with cold spots with the Marmot 20 degree flathead down, which despite a 10 degree warmer temp rating felt much colder that the Haglofs Hypna 30, and did not loft nearly as high as the Haglofst) and opens up fully to use as a blanket in warmer weather. I purchased both the 15 and 30 degrees bags to compare. Both are extremely well made, roomy for a mummy bag, with a great fluffly collar to keep the cold out and a comfy hood. The zipper is one of the best I have seen in a sleeping bag with its snagless feature to minimize snags. This bag lofts up high no matter how much it has been compressed and comes with with a nice, quality compression bag and all cotton muslin storage bag (rather than mesh which is common). Fabric is very comfy and quiet and feels like sleeping in a cloud. I highly recommend the 15 degree over the 30 degree one if you are looking for a all year round bag because you can always open it up if too warm. Temperatures rating appears to be accurate. I would expect the 15 degree bag to keep us warm in temperature in the low 20's and the 30 degree in temps in the low 30s, which is plenty for Northern California.
