We like the extra thickness, but don't like the boosted price. The Men's version is $20 less expensive and more retailers carry it so you are more likely to find it on sale. At this price range, you are getting close the cost of a NeoAir which is much lighter and will be the better option for backpackers who want the lightest stuff.To learn how the women's 40th Anniversary Edition compares, check out the Therm-a-Rest ProLite Plus Women's, as well as our Sleeping Pad Review.
