Men's Base Layer - Thermal Underwear Set with Fleece Lining - Compression Top and Leggings

This men's base layer is a two-piece thermal underwear set, a long sleeve compression top and full length leggings cut skin-tight so it goes on first and everything else goes on over it. If your last base layer rode up and bunched under your jeans the moment you bent down, this one follows the body from the crew neck to the ankle, with contrast piping along the seams.

The inside is fleece lined, so the set holds warmth against your skin from the first minute instead of after the first half hour of moving. The compression cut keeps both pieces flat under a fleece mid layer or a waterproof shell, so you get the warmth without the bulk of loose long johns.

Both pieces are a high-stretch knit of 95% polyester. The top has a crew neck, raglan sleeves, a small G monogram on the chest and a printed Gorgeous Costume wordmark on the left forearm. The leggings have a printed elastic Sport waistband, a piped front panel and the same wordmark near the left ankle.

Wear the leggings under running shorts on a winter run, under hunting pants on the walk in, or under ski pants on the lift, because a skin-tight fit leaves no loose fabric to bunch under your clothes. On its own, the set looks like training gear rather than underwear.

Choose Black/White, Black/Green or Black/Orange. The body is black on all three; the piping and the chest monogram follow the color you pick, and on Black/Green the waistband lettering is green as well.

It is cut skin-tight, so if you prefer a looser feel, size up.

Key Features:

• Fleece lined inside to hold warmth against your skin from the first minute.
• Two-piece thermal underwear set with a long sleeve crew neck top and full length leggings, matched in the same piping color so your whole first layer arrives together.
• Skin-tight cut in a high-stretch 95% polyester knit that lies flat under jeans, running shorts, hunting pants or ski pants.
• Contrast piping along the raglan, side and leg seams gives the set a sporty look you can also wear on its own at the gym.
• Printed elastic Sport waistband on the leggings, with the hem of the top sitting smoothly over it.
• Three piping colors to choose from, Black/White, Black/Green and Black/Orange, each on a black body.
• US letter sizes S through XXXL, and because the cut is skin-tight, sizing up gives a looser fit. The maker supplies no measurement chart.

Activearo makes outdoor gear that does its job and stays out of your way. This set is the layer that goes on first.
