The Merino Long John by OUTRAK is the ultimate winter thermal underwear basic! These long johns have been crafted from merino wool with a mercerised wash for an improved extra soft hand feel. Perfect as a base layer, these long johns are temperature regulating, to keep you comfortable in all climates – regardless of whether it’s the middle of summer or winter! Merino wool is naturally anti-microbial, so you can wear these thermals for multiple days without having to worry about odour management. OUTRAK have developed these with flat locked seams to reduce the chance of chafing and to improve your comfort while layering up for the weather. The design features a regular, comfortable fit for everyday wear! Available in adults and kids sizing to suit the whole family.
