I've had lots of different thermal underwear over the years, but the Merino.tech Merino Wool Base Layer Set is a standout. I used the heavyweight 250 set during a weekend camping trip in early spring. The fabric was incredibly soft and did a fantastic job of keeping me warm during the chilly nights.

Plus, the breathability was impressive; I didn't feel clammy even when the temperature warmed up during the day. The packaging was neat, and I loved the bonus socks—they were perfect for my hiking boots. Overall, a really good buy.

Bought the Merino.tech thermal wear to test on a winter hike in the Rocky Mountains, and it didn't disappoint. The midweight set was just the right thickness: light enough to wear under my gear, but warm enough to keep the chill away. I was particularly impressed with the drying time. After working up a sweat, it dried quickly and stayed comfortable.

I'm 6'1" and around 195 lbs, so I went with the large, which fit me perfectly. The order process was smooth and it arrived quickly.

I wear the Merino.tech base layer set for motorcycle rides and it’s been terrific. Went with the midweight 250, and it strikes a good balance. The natural insulation of the merino wool keeps me warm without overheating when I'm on the move.

The top fits snugly around the chest and waist, which is perfect because it doesn’t bunch up under my jacket. The added bonus socks were thick and cushy, perfect for a rider like me. Great overall value for the price.

The Merino.tech thermal set is super comfy. I wear them as pajamas in the colder months, and they consistently keep me cozy through the night. I initially ordered a large, but it felt a bit loose, so I exchanged it for a medium, which fits much better (I'm 5'11" and 170 lbs). The customer service was excellent during the exchange process.

Perfect for everyday use.

This base layer set by Merino.tech got me through a long weekend of skiing in the Alps. The heavyweight version provided the extra warmth I needed without making me sweaty. The wool is incredibly soft against my skin, and the craftsmanship is top-notch.

I really appreciated the thoughtful packaging, and the extra pair of socks was a pleasant surprise. Highly recommend for any cold-weather activities.

Perfect for all seasons! I bought the lightweight Merino.tech base layer set and have been using it while cycling through the fall and spring. They're super comfortable and do an excellent job of wicking away moisture. At first, I was skeptical about the price, but the quality more than justifies it.

Everything arrived well-packaged and on-time. Truly a useful product.

Ordered the Merino.tech set for my husband who loves to fish early in the morning. He’s been thrilled with it. The set keeps him warm without adding bulk, and he says it’s super comfortable.

The large size was perfect for him (6'2" and 200 lbs). Plus, the wool doesn’t get that funky smell like some synthetic fabrics do. Bonus points for the extra socks, which he says are great with his waders.

These are really good thermals. I used them during a 5-day backpacking trip and they exceeded my expectations. Both the top and bottom layers kept me warm during cold nights and cool on the warmer days.

The heavyweight set is definitely the way to go if you’re facing varying temperatures. They’ve handled multiple washes well without losing shape or quality. Great product.

I recently tried the Merino.tech 250 base layer while snowboarding and I was impressed. It kept me warm on the slopes and didn’t restrict any movement. The fabric feels durable yet soft. I also like that it doesn’t smell after a long day of activity.

I went for a medium and it’s a great tight fit but not too tight (I'm 5'10", 175 lbs). A solid purchase.

The Merino.tech base layer set is good for anyone who spends a lot of time outdoors. I work as a forest ranger and have worn them under my uniform. They keep me warm during the cold morning shifts and breathe well in the afternoon. I've worn them for a couple of weeks now and they still look new.

The free socks were a nice touch and are of good quality.

Great thermal wear for a reasonable price. The fit is good, but what really stood out to me was the quality. The Merino.tech set feels luxurious and you can tell it's built to last.

Used it during a camping trip in the hills, and it was just as you'd want—warm and comfortable. No issues with odor, even after a full day of wear. Easy to wash and dries quickly.

Very nice base layer set. I wore the Merino.tech thermals during a two-week hiking trip in Scotland where weather conditions varied a lot. The midweight set kept me comfortable throughout. I’m 5'9" and 160 lbs, and went with the small which fits perfectly.

The leggings stay in place and the top is just the right length. It’s useful to have something so versatile for different kinds of weather.

Decided to get the Merino.tech thermal set for a Mountaineering expedition. Opted for the heavyweight 250 and it kept me perfectly warm during extremely cold nights. The set is surprisingly lightweight for the insulation it provides.

The order process was straightforward and delivery was prompt. It's one of the better base layers I've used and the extra socks were a helpful addition.

Bought this for a snowshoeing trip and overall, it did the job well. I'm 5'8" and about 165 lbs, ordered a medium which was a bit snug but still comfy. The substance of the wool base layer is pretty good—it keeps you warm without overheating. I also love that it doesn’t get smelly after a day of heavy activity.

The packaging was secure and the delivery was fast.

Was looking for a decent base layer set and found the Merino.tech to be a good option. The midweight set worked well for a fall hiking trip. The material is soft and offers good warmth. I’m 6'0" and 180 lbs, large fitted a bit loose but comfortable.

The overall quality seems good, and the bonus socks were a nice extra. Would recommend to anyone wanting an all-purpose thermal wear.
