Amazing bag! I bought it for my hike through GR20. It’s a hard trek, with highly unpredictable weather. It was sometimes hot, rainy, hail, near freezing temperatures at night. The bag is light, VERY warm, and very very versatile. Depending on sleeping conditions, I used it in every one of its forms: as quilt, as bag, and also as a combo with my pad, tied to my sleeping pad. GR20 offers park tents and bunks in refuges, but me and my friend slept in our own tent, and this bag kept me comfortable in all conditions! There were some very cold and wet nights, I used it together with the hoodlum, and I was dry and toast. It got a bit wet during a night of torrential rains, but dried up in one hour in a wind and sun the next morning, and was good as new again. Not one single complaint. Brava, Enlightened Equipment!
