Men's Thermal Base Layer Set - Slim Fit Top and Long Johns

This men's thermal set is a slim fit base layer top and long johns that go on first, under your everyday clothes, so you start a cold morning warm instead of waiting to warm up. It is one close layer from neck to ankle for building sites, ski trips, shooting days and the walk to the van.

Both pieces are cut from a stretch blend of polyester and elastane, a thermal fabric that holds your body heat close. The top has a crew neck and raglan sleeves, with contrast panels running down both sides. The long johns run full length to the ankle, with matching curved panels on the outer thighs and a wide elastic waistband.

Worried that long underwear will sag at the knees and bunch at your waist? This set is cut slim and the fabric stretches, so it follows your legs instead of hanging off them, and there is no spare fabric to ride up when you kneel, climb or reach overhead. The wide waistband lies flat, so there is no thick band to feel under your belt.

Pull it on before your jeans on a building site, under salopettes at the lift or under walking trousers on a winter hike, then add a jumper and a jacket over the top. It is made to be worn under your clothes, so on a cold morning it is the first thing you put on and the last thing you think about.

Key Features:

• This two-piece thermal set gives you a long sleeve top and full length long johns in one order.
• Thermal fabric holds your body heat close without adding bulk under your clothes.
• A slim fit stretch blend of polyester and elastane moves with you when you bend, kneel or reach.
• Raglan sleeves keep the shoulder seams out of the way under a jacket or rucksack straps.
• The wide elastic waistband lies flat under your belt and keeps the long johns in place.
• Contrast panels on the sides of the top and the outer thighs give the set a clean athletic look.
• Choose from Navy with brown panels, Black with olive panels or Dark Olive with black panels.

Activearo makes cold-weather layers for people who keep moving when the temperature drops, and this set is the layer that goes on first when you head out into the cold.
