Men's Diomede Merino Wool Long Sleeve Crew

I’m a big unit 181cm 108kg, I’ve worn this Diomede base layer over a Nordic brand 3/8 inch open weave thermal (fishnet). This is the best solution I’ve found for my drench sweating. Wether skiing or off road motorcycling. The sweat is moved away from the skin soo well and the Diomede holds the warm air. The stillness after the action does not leave me wet and cold. It’s brilliant 👍

The structure of the fabric combined with the merino wool fiber makes for a very effective cold weather base layer. When worn under a midlayer or other tightly woven fabric, it traps warm air very effectively - much better than other merino fabrics with less structure. The open weave also facilities dumping excess heat when exerting oneself by simply removing the midlayer or opening the midlayer zipper/buttons. Worn alone, the breeze goes right through. The only downside is that the heat trapping structure is susceptible to snags - be careful wearing without an additional layer. I am 6'2" with 41 inch chest and 32 inch waist and the medium is a good fit for a baselayer. The fabric is stretchy and does not feel overly restrictive. Soft and not a hint of itch.

Soft and comfortable and super warm. More expensive than my other base layers, but you get what you pay for.

I loved my hoodie and now I m stoked to have the Long Sleeve without a hood as an option for warmer days.
The fabric is light enough for year-round in the mountains, but sometimes I have too many hoods and bulk around my neck. I love having two great merino tops to switch off depending on the temps.
The softest and stretchiest merino I have tried.. Great work Beringia.

I love base shirts and have a ton (many from Icebreaker, Smartwool, Patagonia). I had high hopes for this one as well, given the comments and look. The shirt does look nice and fits well, but has many issues: 1. It shrinks easily. I have a brand new washer/dryer and the dryer has a moisture sensor and stops just before garments are dry. This shirt unfortunately shrunk a LOT after one dry. Now, it's barely useable as a base layer because of how much it shrunk, and certainly can't be worn in public. 2. Not as warm as any of my other base layers (I spend a lot of time in the Michigan winters fat biking, running and hiking with my pups. Turned out not to be a "go-to" option for warmth. 3. Snags: the outer waffle fabric snags easily. This is a bummer, because it IS a nice looking garment, that, if it hadn't shrunk would look nice as an everyday shirt.
Given all the above, and the price (which is very high relative to competitors), it's hard to rate it very high.
