Description
This MERINNOVATION base layer sleeping loungewear set includes a odor resistant long sleeve top and thermal bottom, available in two weights for different conditions. The 165gsm lightweight option is built for higher-output activity and milder cold - running, skiing, and active hiking where warmth is needed without bulk. The 250gsm midweight handles sustained cold, lower-movement days, and deep winter layering where retained warmth takes priority. Both weights share the same 100% merino wool construction and fiber grade - only the warmth level changes.
Merino wool manages body temperature through its natural fiber structure - the same properties that keep you warm in cold air also prevent overheating during effort. Unlike synthetic alternatives that trap heat at the skin surface, the open knit construction creates natural ventilation that adjusts to physical output. Effective across a range of activity levels, from sustained effort to rest, without creating the temperature swings that require mid-activity layer changes. Works as a standalone layer in moderate cold or as the foundation of a full layered system.
Merino wool naturally resists the odor that builds up in synthetic fabrics after extended wear. This odor resistance set maintains freshness through multiple consecutive days of use - on multi-day hikes, travel days with limited luggage, and back-to-back training sessions where laundry access is not always available. This makes it practical for frequent wear without needing to wash after every use. A base layer you trust changes how you approach cold weather. Instead of packing around uncertainty - bringing backups, second-guessing conditions, washing between every use - this set handles the full range.Â
The included wool accessory covers the next need before it arises. Fewer items, more confidence, consistent comfort regardless of what the day requires. Built to handle cold-weather demands across a full season, this set earns a lasting place in rotation. Consistent from the first wear of autumn through late winter, it works as a go-to layer for anyone who needs reliable warmth without bulk, whether the day calls for activity or rest. A dependable wardrobe anchor for the colder months.
- ULTRA SOFT AND COMFORTABLE - The merino wool base layer set is available in lightweight 165 GSM and midweight 250 GSM fabric. Superfine 18.5-micron merino wool next-to-skin comfort provides all-day comfort without itch. Package includes: a wool thermal baselayer set plus a bonus pair of socks or neck warmer (USD15 value)
- TEMPERATURE REGULATOR AND BREATHABLE - Wool base layer mens is lightweight and breathable for outdoor activities. The merino wool helps regulate body temperature, providing ideal insulation in cold conditions, keeping you comfortable all day long
- MOISTURE WICKING & ITCH-FREE - Merino wool fibers naturally wick moisture, making this novelty pajamas set suitable for indoor or outdoor activities without feeling damp or clammy. Stays fresh longer between washes.
- MACHINE WASHABLE MERINO - Unlike delicate wool, this set survives the washing machine. Wash in cold or warm water up to 86°F (30°C) - retains softness, shape, and color through repeated washing with no shrinking, fading, or color bleeding.

Care Instructions
Merino is easier to care for than most people expect — and because it naturally resists odor, you'll wash it far less than cotton or synthetics.
Washing
- Machine wash cold (30°C / 86°F) on a gentle or wool cycle
- Use a mild detergent — no bleach, no fabric softener (softener coats the fiber and reduces its natural performance)
- Wash with similar colors, inside out
Drying
- Lay flat to dry away from direct sunlight — this keeps the shape and fit
- Do not tumble dry, do not wring
Between wears
- Air it out overnight — merino refreshes itself and is usually ready to wear again
- Spot-clean small marks with cold water instead of a full wash
Storage & pilling
- Store folded, clean and fully dry
- Light pilling in high-friction areas during the first weeks is normal for natural fibers — remove it gently with a fabric shaver and it fades over time

MERINNOVATION Merino Wool Base Layer Set for Men 100% Merino Wool Pajamas Set Thermal Sleep PJS Lite - Midweight Top, Bottom
The complete base layer, in one box
Matched top and bottom in the same merino knit — for sleep, layering, and travel.
One box. Every base covered.
A matched top and bottom in the same knit — thermals for the slopes, pajamas for cold nights, a first layer for winter travel. Buying the set costs less than the pieces on their own.
Sleep cooler, wake fresher
Merino moves moisture away instead of trapping it, so you don't overheat at 3 a.m. and don't wake up clammy. It's the same reason alpine guides wear it for weeks straight.

Will it itch?
No. We use superfine merino fibers that bend on contact with skin instead of prickling it. If you've only worn traditional wool, the difference is immediate.
Can I get the top and bottom separately?
Yes — but the set is priced below the two pieces combined, in the same knit and dye lot so they always match.
Good for sleeping?
It's one of the most popular uses. Merino buffers temperature swings overnight, so you're less likely to wake up hot or chilled.
How do I wash it?
Machine wash cold on a gentle cycle, lay flat to dry. No softener, no tumble dryer. Between washes, just air it overnight — merino refreshes itself. Full details in our care guide.
