For skiing, I’d prioritize **200–250 gsm merino** for a good balance of warmth, moisture management, and durability. Independent 2026 testing consistently puts **Icebreaker 200 Oasis** and **Smartwool Classic Thermal Merino 250** near the top, with the 250 being better for colder resort days.…

Smartwool Classic Thermal Merino Base Layer Crew - $125.00 (Smartwool)
Icebreaker Merino 200 Oasis Long Sleeve Crewe - $120.00 (icebreaker)
Arc'teryx Rho Merino Wool Long Sleeve Base Layer - $120.00 (SCHEELS)
Smartwool Intraknit Thermal Merino Base Layer Crew - $150.00 (Smartwool)
Minus33 Yukon 400 g/m² Merino Crew - $149.99 (Minus33 Merino Wool Clothing)
Best overall for resort skiing: Smartwool Classic Thermal Merino 250 — 100% merino, 250 gsm, warm enough for genuinely cold lift rides and relatively simple/durable construction. Current price is around $125 direct from Smartwool.
Best all-around: Icebreaker 200 Oasis — 200 gsm, 100% merino, a little lighter and more versatile. Excellent if you ski in variable temperatures or tend to run warm. Independent testing gave it a 4.5/5 and praised its breathability and versatility.
Best for durability: Arc'teryx Rho Merino — its merino is wrapped around a nylon core, giving you a more abrasion-resistant construction than pure merino. That's particularly attractive if you want something to survive many seasons.
Best for high-output/backcountry skiing: Smartwool Intraknit Thermal — engineered ventilation and a more athletic construction make it better suited to skinning or strenuous skiing than a very warm 250-gsm layer.
For brutally cold days: Minus33 Yukon 400 — 400 gsm is substantially heavier than typical ski baselayers, so I'd choose it for very cold, low-output days rather than spring skiing.
For the widest selection and easy returns, REI is a particularly good place to start; its current Labor Day sale is running through September 7, 2026, and includes merino base layers. New York Magazine You can also buy directly from Smartwool or Icebreaker, which is useful when you need a particular size/color.
One durability tip: if "long-lasting" is your #1 priority, consider a merino/nylon blend rather than insisting on 100% merino. Pure merino is wonderfully comfortable and odor-resistant, but nylon reinforcement generally improves abrasion resistance and lifespan.
If you tell me men's or women's, your typical ski temperatures, and your budget, I can narrow this to the 3 best sets (top + bottoms) for you.

Icebreaker 200 Oasis Long Sleeve Crew - $120.00 (Backcountry)
Smartwool Classic Thermal Merino Crew - $125.00 (Smartwool)

Smartwool Intraknit Merino 200 Crew - $150.00 (Backcountry)
Icebreaker Merino 200 Oasis — best all-around choice. 200 gsm, 100% merino, comfortable enough for resort skiing and versatile enough for hiking/travel. It has been repeatedly rated among the best midweight merino layers.
Smartwool Classic Thermal Merino 250 — best for cold resort days. The 250-gsm fabric is substantially warmer than a 200-gsm layer, making it my pick if you're often skiing in genuinely cold temperatures.
Ortovox 185 Rock'N'Wool — best for ski touring/high output. It's lighter at 185 gsm and has an excellent warmth-to-weight ratio; the 19-micron merino is also particularly comfortable.
Ibex Woolies Pro Tech — best if durability is your priority. It's an 85% merino/15% nylon construction using Nuyarn, which sacrifices a little of the "pure merino" feel for improved durability. WIRED reports getting years of use from these.
For the easiest comparison and good return policies, REI is a particularly good place to shop Icebreaker and Smartwool. For Ortovox, Icebreaker, and Smartwool, Backcountry currently has a broad selection. You can also buy directly from the manufacturers:
For maximum longevity: don't automatically choose the thickest or softest 100% merino. Merino is inherently more vulnerable to abrasion than synthetics, so a quality merino/nylon blend can be the better choice if you're hard on your gear.

I'd actually consider a merino/nylon blend rather than insisting on 100% wool. Ibex's Woolies Pro Tech, for example, uses 85% merino/15% nylon; WIRED specifically found the construction more durable while retaining the benefits of merino.
For a typical Wisconsin/Colorado/Rockies ski trip: I'd buy Smartwool 250 if you're mostly resort skiing in cold weather, or Icebreaker 200 if you run hot or ski hard.
If you tell me your budget, men's/women's, and whether you're primarily resort or backcountry skiing, I can narrow it down to the 3 best options currently available and compare prices.
For skiing, I’d prioritize **200–250 gsm merino**: warm enough for most resort days without being excessively bulky. If longevity is your top concern, a merino/nylon blend can outlast 100% merino, especially if you ski frequently.…

REI is probably my first stop because you can compare Smartwool, Icebreaker, Arc'teryx and other brands in one place and try them on. For example, the Arc'teryx Ionia is currently listed there at $90.
Direct from Smartwool or Icebreaker is ideal if you've already decided on the model; both have extensive current selections. The Smartwool Classic Thermal Crew is currently $115 direct.
Backcountry is another excellent option, particularly for ski-specific gear; the Icebreaker 200 Oasis is currently listed at $120.
I'd rank them Ibex Woolies Pro Tech > Smartwool Classic Thermal > Icebreaker Oasis. The Ibex is particularly interesting because its 85% merino/15% nylon Nuyarn construction is designed to improve durability; WIRED reports using the Woolies for years and specifically recommends it for skiing and other technical activities.
My simple recommendation: get Smartwool Classic Thermal 250 if you ski in genuinely cold conditions; get Icebreaker 200 Oasis if you want maximum versatility.

1. Icebreaker 260 Tech — best overall for skiing
100% merino, 260 gsm, warm without being excessively bulky. Icebreaker has an especially strong reputation for longevity; skiers report keeping some pieces for many years.
2. Smartwool Classic Thermal Merino 250 — best proven workhorse
A 250-gsm, 100% merino layer that's particularly good for genuinely cold days. It's also widely available, so it's easy to try different sizes/fits.
3. Ortovox 185 Rock'N'Wool — premium/lightweight choice
At 185 gsm, it's better for high-output skiing, touring, or warmer conditions than frigid lift days. Ortovox is worth considering if you prioritize technical construction and a close fit.
4. Minus33 Chocorua — best value
100% merino at around $90, making it considerably less expensive than many premium competitors. Recent testing rated it particularly highly for value.
If you're buying just one set: I'd get Icebreaker 260 top + matching bottoms for cold-weather resort skiing. If you tend to run hot or ski aggressively, go Icebreaker 200 Oasis instead—the 200 gsm version is more versatile and dries quickly.
If you tell me men's or women's, your typical ski temperature (e.g. 10–30°F), and budget, I can narrow it down to the 3 best sets currently available.
