User Review: Therm-a-Rest Women's ProLite Plus
Source: bought it new
Price Paid: $67
Very warm, but a bit bulky when packed and compressed. Durable and non-slip. Tested 2011 version.
Can't attest to the durability yet (1 trip, so far) but should last a while with good care. I'm a cold sleeper and the R-value was great. I'm a guy and a side sleeper so the extra padding was great, the height matched me exactly also so I wasn't carrying any extra pad.
Downer: Bulky when packed (plan to store in a dry sack lashed outside my pack)
Tip: Blow it up with a few breaths early on in camp and adjust the valve while lying on it. Store inflated under your bed.
