Mylar
This is the material used in emergency and thermal blankets, as it does a phenomenal job at retaining body heat and is light or easy to carry. While, it doesn’t offer much comfort, especially when comparing mylar to other camping blankets materials, it’s incredibly light, easy to carry, and essential for emergency use.
Polar Fleece
Like wool, polar fleece is able to trap air and does not absorb moisture, but it tends to be significantly lighter and less itchy. That being said, fleece blankets are also pretty warm and are really comfortable to use. Fleece blankets also take less time to dry compared to wool blankets. Blankets made of fleece are also light and suitable for camping. It is, however, important to note that fleece blankets are highly flammable, and this is a great disadvantage, especially in camping.
Sherpa
Sherpa is a warmer and softer version of fleece than the standard polar fleece. Also made from synthetic fibers, this material has been making sheep jealous for the past couple of decades, as it provides the same level of warmth as wool, but with a much softer and cozier feel. Truly the material of our generation, Sherpa is the ideal material for camping.
Polyester
This is a synthetic fiber that is incredibly light, yet ultra-durable. Blankets made from polyester are great, especially during the wet season, as they’re very highly water-resistant. Polyester are used as the waterproof backing on most waterproof blankets, as they do a great job at keeping you dry, especially during a stormy & wet camping trip.
