I decided to buy this at the last minute before my first backpacking adventure in June, where temps in the redwoods were around 45-50 at night. I had read about the benefits of a sleeping sheet - keeps your sleeping bag clean longer, and added comfort. I haven’t tried other brands but this one is perfect for my needs. It’s a little odd at first to get into since it’s just open on one side, and it was paired with the Nemo Forte 20 degree (not quite as mummy as others but still a cocoon). It worked well in combination with the bag and was super helpful to have a light but comfy layer when I got too hot in the night. Unzipped the bag but still felt protected and warm enough. I love the fabric - soft and stretchy lightweight jersey that doesn’t fight when you are rolling around (which I do a lot). My next trip will be late summer and presumably a lot warmer, so I’m taking this with a down blanket vs sleeping bag.
