Men's Diomede Merino Wool Long Sleeve Crew

The Diomede is well worth the investment. The great look is obvious and the quality is a pleasure to wear.

This top is seriously warm when layered. I wore it in the Arctic -20 deg C with high winds, as a base layer it got a bit hot depending on my mid and top layers. It seems to trap air for warmth very effectively. BTW, as the washing instructions will tell you, do NOT put it in the dryer :)

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 texture of this shirt is incredible. Its waffle knit keeps you warm and wicks sweat out in a comfortable way that doesn't ever stick. The stretch in the fabric makes it an easy wear but does hold a bit of stretch after a few days of wear. A cold wash and hang dry is what resets it.

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.
