If you're wondering about a perfect pad for all seasons you have just found it. The pad is very light and packs down into a tight stuff sack. Additionally, the material is very durable and very comfortable, once fully inflated, it stays firm and retains shape as you snooze. It does take some time to inflate if you have it compressed for a long time, but if you manually blow into the valve it works great. However, in freezing conditions do not manually inflate, if the temperatures are cold enough the moisture from your breath can condense inside, which can damage the pad (must be VERY cold). This goes for all sleeping pads, and bottom line this is a fantastic pad worth the money for sure. If you're still using a large foam roll pad, you will be blown away by switching the Prolite 4 in comfort up, weight down, packability up, temperature management up, and you can read the other 100 reviews if I haven't convinced you.
