What is Warmth to Weight?

Warmth to Weight is a measurement used to evaluate the insulation abilities of a piece of clothing in relation to the weather conditions.

What is the best fabric for insulation?

The best fabric for insulation is down.  This is why survival sleeping bags, thermal jackets etc will use it.  We predominantely use Primaloft because it is incredibly soft, lightweight and breathable with excellent water repellency so you remain dry, warm and comfortable, even under the most extreme conditions. And ounce for ounce, Primaloft is as warm as down. The Primaloft microfibres are similar in size and shape to down, resulting in nearly equal insulating performance when dry and even better when wet.
