Dimensions: 66” x 21” x 2” R 4.8 Weight: 755 grams I’m not sure why this model is called “Women’s”. It’s a bit shorter (66”), a tiny bit thicker (2”) and a bit warmer (R 4.8) than the Regular. Thermarest also says that that different types of foam are used strategically to give extra warmth/comfort where needed. Am I less of a man because I want these things too? No! However, it’s too short for me and my wife doesn’t use it anymore so I guess it’s time for it to move on. Detailed review on Youtube https://www.youtube.com/watch?v=evrvhaX2QTs
