Why Merino Wool?

merino wool is a reactive material that adapts to your body's temperature, perfect for any weather

Adaptive Clothing

Unlike other materials, Merino wool is a reactive material that adapts to your body's temperature. It regulates so that you are never too hot or cold in any weather.

merino wool is a lightweight, naturally warm fiber derived from Australian sheep

Naturally Warm

Originating from Merino sheep from Australia that endure temperatures as low as 5 degrees, Merino wool is a lightweight, naturally warm fiber.

merino wool has thinner, finer fibers that make it soft to the touch and cause no itch!

Itch-Free

Unlike regular wool fiber that is heavy, coarse, and itchy, Merino wool actually has thinner, finer fibers that make it soft to the touch and cause no irritation to the skin.

merino’s fibers are smaller in diameter than other wool which bend softly with increased flexibility

Ultra Soft

Merino’s fibers are much smaller in diameter than other wool which gives the fibers the ability to bend softly with increased flexibility. The result? Soft to the touch.

These merino wool layers in250/450 gm, are soft,warm, comfortable and not bulky. Wash gentle cycle (I suggest using woolite) dry flat and dries quickly! A great investment!!!

The quality of this heavyweight merino baselayer is exceptional. It’s thick with the perfect amount of stretch and I’d say fits true to size. For reference, I’m 5’7”, 170, 38C, and the large fits close to the skin as needed with a proper base layer, but has enough stretch to be very comfy. I can easily wear with a mid-layer and think it would also work as a mid-layer with a thinner base layer. The stitch detail is super cute, too.

I ordered the beautiful wine color, heavy weight thermal merino wool, size M and it fits better than the small. I am5’1” 110 lbs. the small is snug. I love the fit but I wouldn’t be able to wear a thin base layer under it.

This top is a perfect fit, the colour is gorgeous, it’s lovely and warm. Sometimes I wear this as a base layer and often as a top layer, either way is great.

The shirt is super good material, thick weave, warm and seems to be well made. I haven't worn it much yet so it's hard to say for sure, but it seems to be really good quality. I would buy several based on quality but the fit is a problem for me. Size medium was long which seems to be the norm for wool shirts. It was very snug, even a bit tight on the arms and torso while the chest and shoulders were a little roomier and a good fit. Ideally, it would be just almost snug so I could wear an undershirt with it. So, I tried a large hoping it'd be a better fit. The chest/shoulders on the large were too big, it was way too long, and the torso and arms were still really snug. Basically, they seem to be made for the stereotypical (but unrealistic) busty, hourglass figure with the shoulders of an olympic swimmer. For reference, I am a medium build, within a normal weight range. I am returning the large and still thinking about keeping the medium. I really want to like these because they are so cosy and the material so nice. The medium would be fine if I liked it next to skin. It will work well for the lighter weight shirt that I would wear more as a base layer.

Keeps me warm and I really like the tops in various weights. I like how easy these are to wash and lie flat to dry. Will be packing them for a Mammoth ski trip next week and a spring trip to Europe. Finally, I have clothes that keep me warm. Having no thyroid makes it difficult to get warm but these woolies work.

Machine washed and dried it before I wore it. It came out fine even though instructions recommended hand washing and drying it flat. I may do that in the future. The M size fits perfectly (I'm 5'6", 125 lbs.). I wore the shirt with a thin sweater and a jacket for a full day. It wasn't at all itchy, and it kept me warm. Some reviews mentioned pilling, but that happens when you wear another layer over the shirt; and the two garments rub against each other. The solution to that problem is to use a fabric shaver to eliminate the pilling. So far, I'm very happy with the purchase.

This top was not warm at all.I have continued to wear my 32s as the base for all tops,living in the mountains you need as much warmth as possible.I purchased this and the bottoms to keep warm as they advertised these as the warmest you could purchase.Not even close.Pj top warmer,unless you’re wearing a warm coat on top,consider something else.

Excellent quality sweater, very soft but thick, as advertised. It’s for very cold weather so I’m going to wear the lighter weight tonight and will review that later but the heavier weight is very sturdy, will last forever. It runs small so I’d get a size bigger, unlike the medium weight (300g turtleneck), which does run a bit larger and looser. I absolutely love this 400g weight, not surprised it looks like they’re not making it anymore, quality like this is so hard to find these days. Does look like underwear, not decorative, but ample, good solid coverage.Update November 26, 2020:Just bought another one. Because I tried to find it before and couldn’t. Just in case they stop making it. Very good quality. Love the one I have. Still haven’t received the new order yet but it is Thanksgiving. Tracking says I’ll get it last week.... Doesn’t fill me with confidence. We’ll see
