Temperature rating:

Mountain Designs sleeping bags are independently laboratory tested
according to EN 13537 to ensure you have the right sleeping bag for the right climate.
The temperature rating of our sleeping bags are indicated in 3 different measurements:
"T-Comfort" – Based on the a temperature at which a standard adult female is deemed to be able to have a comfortable nights sleep.
"T-Limit" – Based on the lowest temperature at which a standard adult male is deemed to be able to have a comfortable nights sleep.
"T-Extreme" – The minimum temperature a standard female can survive in.

DowntekTM Insulation: The DowntekTM treatment shields the insulating down clusters from moisture, allowing the down to continue insulating even while wet, preventing the clumping of the down clusters which stops the down from insulating. DowntekTM adds no measurable weight, is all natural and is environmentally safe.
Trapezoid Baffle Construction: This is the most thermally efficient baffle design, with the placement of the baffle seams offset, this ensures that cold air does not get through the stitching placement. This design also prevents down migrating from one side of the baffle to the other, ensuring and even dispersion of insulation throughout the sleeping bag.
Pertex® Quantum: Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft. It is precisely constructed from incredibly fine yarns, to trap still air and improve the efficiency of insulation. The fabric is treated with a durable water repellent (DWR) finish to shed light rain and snow to provide additional weather protection. Pertex® Quantum is also lightweight, packable and wind resistant.
