The Marmot Plasma 30 Down Long Sleeping Bag is one of the most sophisticated sleeping bags Marmot has yet produced for two-season use when you want minimal weight to allow you to move at speed on a backpacking trip.

One of the features of this bag is the Insotect flow vertical baffle system that maximises the effective thermal efficiency of the sleeping bag while also saving weight.

Not only the very lightweight Pertex outer fabric but also the down insulation benefit from a durable water-repellent (DWR) treatment that causes water to bead up and roll off rather than penetrate the material.

The extended length of this version of the Marmot Plasma will suit taller users but a standard length version is also available.
