ROCK FRONT 350 Summer is built for summer trips, hiking, and camping. Center-zip convertible mummy bag concept gives it more versatility than a standard summer sleeping bag, making it easy to use as a sleeping bag, a blanket, a quilt, or a hammock underquilt.
Filled with 350 g / 12.35 oz of 800 fill power goose down, it provides comfortable sleep on cool summer nights. In warmer weather, bag can be opened fully and used as a blanket.
To make it more durable, shell uses 20D ripstop nylon with DWR, while lining uses softer 15D nylon for better next-to-skin comfort. Special loops allow bag to be attached as a quilt or used as an underquilt for hammock camping. Drawstring footbox can also be opened for extra ventilation when needed.
Materials have hydrophobic treatment, which helps the sleeping bag perform better in damp conditions.
