Sea To Summit Reactor Extreme Liner Mummy w/ Drawcord Compact Right Regular Sleeping Bag

The THERMOLITE Reactor Extreme liner is Sea to Summit’s warmest knitted sleeping bag liner. If your adventures take you to colder climates, the Reactor Extreme will add plenty of warmth to a sleeping bag. Plus in warmer weather, it can be used as a 'stand alone' sleeping bag. The hollow core fibers of the THERMOLITE fabric work like a polar bear's fur and, along with the knitted structure, trap plenty of insulating air. Super soft and amazingly stretchy, the Reactor Extreme uses a heavier version of THERMOLITE to provide extra warmth for an incredibly comfortable night’s sleep. Use one to build your cooler-weather sleep system and to help keep your sleeping bag clean too.

THERMOLITE

• The Reactor Series Sleeping bag liners, the Venture, Traverse and Basecamp synthetic Sleeping Bags and the foot boxes of the Women’s Altitude and Journey down Sleeping Bags use hollow core THERMOLITE fiber to add warmth. These fibers trap extra air for insulation (just like the hollow-cores of polar bear or caribou fur). In the liners, the knitted THERMOLITE fabric is soft and stretchy and comes in three different weights: 80 g / m2 fabric used in the Reactor and the underside of the Compact Plus liners; a 110 g / m2 fabric which is used in the Extreme, and the core and foot box of the Compact Plus liner; and the Fleece, the warmest of all the fabrics.
