Description

350 Summer is a down sleeping bag designed for summer travel. 350g (12.35 oz) of 800 Fill Power goose down ensures a comfortable sleep on cool Carpathian nights. In warm weather, you can unzip the sleeping bag and use it as a blanket.

To make it more durable, as the outer fabric we used 20 denier nylon with DWR impregnation and ripstop reinforcement. The inner 15 denier nylon is soft and pleasant to the body.

Special loops allow using the sleeping bag as a quilt or underquilt for sleeping in a hammock.

Materials have hydrophobic impregnation, which makes the sleeping bag more resistant to wet conditions.
