This 4Season system has advantages when you find yourself in colder weather than expected.
Key Features
✅ It can be adjusted to a wide range of temperature conditions without adding weight or bulk.
✅ With just the oversize open cell foam pad, most people are comfortable down to about 40 F / 4 C.
✅ Adding the space blanket under the pad should take you down to below freezing.
✅ The space blanket can be placed above or below the pad depending on the temperature, humidity and what works best for you.
✅ If you have been wearing a jacket during the day, spread it out on top of the open cell foam pad or anything else in your pack that has insulation value such as extra clothing, towel, hat or socks to get you down into the twenties, maybe even lower.
