Mammut Perform Fiber 20 Sleeping Bag

Mammut Perform Fiber 20 Sleeping Bag is a warm, light and compressible sleeping bag. The polyester fiber filling is soft and fluffy and will not clump or lump. It is also very durable, ensuring that you will receive many years of enjoyment from your sleeping bag. You will be snug as a bug in a rug in this well-insulated bag made of Ultra-Sil Down™ technology. The Pertex® Quantum surface on the inside reflects heat back where you need it most, making these sleeping bags perfect for cold weather camping or mountaineering trips.

A simple two-way zipper gives easy access, whether you prefer to zip together with your partner or zip down to increase airflow when temperatures start to rise. These things make them an ideal choice for expeditions lasting between one and three weeks; they are also suitable for mountain tours in even very cold places because their Durable Water Repellency treatment means that moisture can easily be removed with one quick shake after exposure to rain or snow without compromising their lifetime performance.
