What Lies Beneath

Arc’Teryx Satoro AR Zip-Neck Top and Bottom
The ideal lightweight baselayer feels like a second skin, moving with you, breathing with you, keeping you warm and dry no matter the activity. The Satoro does just that thanks to a core-spun merino wool that fits like a glove and holds up to all kinds of abuse. The top’s high collar leaves no neck gap, and the bottom’s articulated design enhances mobility. It’s the little things. Top, $139; bottom, $109

Flylow Women’s Andrea Henley and Shregging
Leave it to Flylow to get this clever set to market. The Andrea Henley and matching Shregging are equally at home beneath your ski kit plowing the knee-deep and perched on a barstool sipping an après microbrew, proving that baselayers don’t have to be dull, and they don’t have to be hidden away. The polyester-spandex Andrea Henley is wicking, warm, and great-looking with jeans and boots on a non-slope-bound day. The stretchy, breathable Shregging, with its low-profile thigh pockets, low-slung waist, and pretty pattern, can double as an adorable legging for yoga, errands, or just lounging around. Top, $85; bottom, $85

Salomon Primo Warm Seamless Tee and Tight
Salomon’s first-ever baselayer delivers exactly what we expected: comfort, breathability, and warmth in a simple package. The Primo is a polyester set with added nylon and elastodiene for durability and ease of movement. Ribbed reinforcements in targeted spots allow ventilation and lengthen the garments’ lifespan. They work with you while you’re working hard. Top, $85; bottom, $80

Sweet Protection Alpine Half-Zip Top and Pant
The Alpine baselayers represent the best of what merino has to offer. They’re soft and supple, cozy, warm, breathable. They’re also double-layered on high-traffic areas like the elbows, wrist cuffs, and knee for added durability. Merino is antimicrobial and anti-odor—so even more reasons to make this your go-to from early winter’s deep freeze until the spring thaw. Top, $120; bottom, $90

Trew Gear Chill Top and Bottom
The Chill employs NuYarn, a merino technology, to serve up a midweight baselayer that’s soft next to the skin, wicking, breathable, and 16 percent more durable and 35 percent stretchier than 100 percent merino. The merino yarn is untwisted and then wrapped around a nylon core, strengthening it. The color-block styling, snug hood, and thumb holes are gravy. Top, $139; bottom, $119
