Factor 1 Unisex Long Sleeve Base Layer Tops are one of the best lightweight thermal underwear ranges for general outdoor use.
These unisex tops are manufactured from stretchy tubular 100% polyamide ribbed fabric with a hydrophilic treatment for superior moisture management.
Generous body lengths allow a decent amount of fabric to be tuck in to your trousers, helping to prevent lower back exposure. The set-in sleeves provide a close but comfortable fit around the armpits and shoulders, maximising insulation and moisture transportation. The double thickness cuff provides extra protection around the wrists, as well as helping to prevent the loss of trapped warm air, whilst the round neck design stretches when placed over your head.
These base layers cross over in to anything from, skiing, through to hiking and camping, and can be used in combination with Sub Zeros Factor 2 mid layers for extra warmth in extreme conditions.
