These long johns, like all Woolpower garments, are made in Sweden from a blend of merino wool and synthetic materials. They feature a terry-loop knitting on the inside which traps air and provides a maximum heat retention while wicking moisture away from your skin.

Woolpower long johns are made of a circularly knit fabric, and as a result, have no lengthwise seams down the legs. A gusset in the crotch ensures optimal comfort, and leg cuffs are sewn in.

If you're doing something where you're moving very little in cold weather i.e. hunting (where you're sitting in a tree stand), ice fishing, perhaps you're a crossing guard where there's not much movement, 400g will be the way to go.
