If you���re looking for a versatile piece of equipment, the cloak series blankets are for you. I have used the Cloak 15 now on 3 trips with a low temp range of the high 30���s to high 40���s. Most nights I have been much more warm than cold. I have no doubt that I could easily take the Cloak 15 below freezing temps. You would need proper headwear because of the lack of a hood. Being from Michigan I have a great appreciation for synthetics, cold and damp in the winter and hot and muggy in the summer. When I moved West I fell in love with down but have always been weary of moisture. Hydrophobic down has helped ease those worries and at 1lb 4 oz you hardly notice the bag in your pack. I have 5 other bags currently in my house, 2 of which are mine, and the cloak is the softest to touch by far. It���s not even close and the other bags are quickly falling out of circulation. If you���re broad shouldered and a side sleeper, you could have some issues with coverage. Otherwise the size is not an issue. There are no zippers... let me say that again, no zippers! On warm nights you can sleep half covered and on cold night the draft tube and weighted side baffles tuck you in and keep the cold out. The fabric seems durable for its weight. I have Border Collie mix that sleeps in the tent with me and so far the Cloak has held up just fine. The Cloak 15 is quickly becoming one of my favorite pieces of gear I have ever used and is my go to for backpacking. Brooks-Range designed a great piece of gear for the person that demands performance in a variety of conditions.
