Familiarity: I've put it through the wringer
After much research, my wife and I decided to try the Synmat UL 7 with an eye toward our next major trip, which was a 3-week backpacking trip through the Yukon.
We tested the mats in Colorado and Utah all summer and loved them, but the real test was cold, wet weather in the Yukon, which was almost a daily occurrence. These mats kept us aloft in soft, elevated warmth no matter what the temperature.
We did get a bit of condensation build up due to the general dampness of the trip, but I called Exped customer service and they gave us detailed instructions on how to rid the moisture from the mats. We did as they suggested and it worked great.
By far the most comfortable, convenient and lightweight/packable sleeping pad I've ever used. I would strongly recommend this product to anyone.
