Review: Worth the money, long lasting, will keep you warm; Great base layer - These base layers have kept me warm over several winters now. Last winter, I wore them all the time. I took them to Finland, and they helped keep me warm there. They feel good against the skin. The pants have a couple of little holes in them, but they don't seem to be fraying. Great value, fits great.

## Questions & Answers

**Q: Won't merino wool feel itchy? And what does 17.5 micron mean?**
A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances.

**Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?**
A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally

**Q: Which weight should I choose — 165, 250, or 320 g/m²?**
A: 165 g/m² — active pursuits, travel, spring/fall, 40–60°F. 250 g/m² — cold weather, most outdoor activities, 25–45°F. 320 g/m² — frost and low activity, 10–35°F, extreme conditions. Rule: the higher the activity level — the lighter the weight you need

**Q: Where does the merino wool sourced from and is this product certified?**
A: Our products are made from New Zealand merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100.

**Q: Does it fit true to size?**
A: Choose your regular size if you prefer slim fit. For more relaxed fit order size up

### ⭐⭐⭐⭐⭐ Even a Sasquatch would like these
*by M***H on September 9, 2025*

Bought this as gift for my skeptical Salt of the Earth Hubs who was not aware yet of the true superiority that is merino. His face dropped and I had to put his chin back into place when he asked How Much. I was utterly unfazed and ignored his protest. I easily got past his merino gear green inexperience and told him to ‘just try them because these will change your life’ with a grin. To put it short and sweet: He proceeded to basically only take them off to wash over the next five months. His only comment, actually Using His Words: he wanted another set. This, so he always had some clean and multiple weights so he could regulate better and choose depending on the weather forecast for the day he’d be out. I noticed his old synthetics were crumpled in the bottom of his gear bags when he’d come home. The merino were always within reach on top, and gasp, folded! High Praise from this man, folks. It should be stated he is THE case for the legitimacy of merino, and these extremely well priced merino sets: he is a heavy equipment operator that works outside on top of mountains in some of the most extreme winter environments on earth and loves it. For you, the reader’s purpose, let’s just agree to put aside the elephant-in-the-room Crazy Factor of that last sentence for now and stick to the underwear. All I can say in his defense is this world takes all types. That’s only important here to mention since he’s not a dude that sits around in it next to a cozy fire all winter sipping from a tea cup. (That’s my job, lol.) This set was put to a legit durability test and in incredibly harsh conditions and stood up. Once prompted for more detail, and translating out of his customary grunts, shrugs and sighs, he said [paraphrasing]: he stopped noticing whether or not his body was cold or hot since he was the perfect temperature all the time and stopped sweating whether in or out of a machine. He didn’t have to wear nearly as many layers in general. He didn’t have to strip ones off or put other ones on depending on where he was and what was happening nearly as much. He stayed warm even when outer gear got wet with frozen sleet driving and he had to move back and forth outside from truck to machine to truck. He wasn’t losing gear and other layers from job sites, trucks, machines or in the snow nearly as much either from stripping off and forgetting. The merino set remained odor free for an entire work cycle between washings so he reused them everyday. They stayed true to fit and didn’t stretch out of shape even wearing for long periods and for multiple days in a row. All day comfort second skin feel. No bunching in the armpits nor crotch. Ordered the 2XL, biggest they offer I think. He’s normally 3XL big and tall, so I wasn’t sure if these would fit but as a first or second layer snug is good. His back and shoulders can be a challenge to find proper fit for and I often tailor his clothes and gear, but these are perfect with long arms and a long torso design to accommodate various sizes and shapes. Spare to tuck in even! Fantastic!: This is important since he sometimes has to do mechanical repair on the fly. On top of a mountain on the machines, before this merino set, his lower back would sometimes come home chaffed and raw from cold exposure from these situations. A red burn from bending over with elements beating on him, not wanting to touch his clothes since his hands and outer gear coated with grease, tucking back is not a desirable option. The winds are basically trying to tear everything off so to have it stay in place and enough fabric to remain tucked in? chef kiss. Going into this next winter season depending on where he is going this year, we’ll get another set at a different weight. He said he wanted that versatility this time.
