DoubleLayer hammocks are perfect if you love nature and enjoy adventures that involve sleeping a few nights outdoors.
They are made out of waterproof ripstop (first layer) and breathable microripstop (second layer), are light and extremely compact, so they can easily fit your backpack or any other luggage you have.
Used together with a sleeping bag and a pad (placed between the two layers of the hammock) they make a great shelter and a nice alternative to a tent.
