The Patagonia Men’s Merino 3 MW Bottom is a merino wool base layer for winter trekking to backcountry skiing. The blend of merino wool, Capilene, and spandex creates a soft, stretchy mid-weight layer for keeping warm during your latest winter adventure. The combination of merino and Capilene work to wick moisture off your lower half and dry it out quickly, effectively keeping you comfortable for the whole day. The waistband is elastic and low-bulk for easy layering and a functional fly with gusseted crotch for convenience. The wool naturally resists odors too, so you can keep them on while huddling in your sleeping bag.

Men's Fit Guide Details & Info
Patagonia's measurements refer to body size and NOT garment dimensions. Sorry for yelling about it.
Each Patagonia product is designed and shaped specifically for its intended use, and below are their generalized four fit descriptions, and details about each fit. The Patagonia fit for each style can be found in the product description features or specifications.
FORMFITTING • Conforms to the body's contours.
SLIM FIT • Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.
REGULAR FIT • Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers. Men's regular fit pants have a slimmer fit through that thigh, lower leg, and cuff.
RELAXED FIT • Drapes loosely on the body. Men's relaxed fit pants have a bit of extra room through the hip, thigh, lower, and cuff.
Rated 5 out of
Warm and feels greatI bought these as a warm base layer for winter activities to replace cotton. ,,,,I left the pants in my basement for a few hours to see how it would feel putting them on while they were cold. Compared to cotton long underwear they were a tad colder when first put on but warmed up fairly quickly. I spent the day wearing them but never felt that I was wearing long underwear unlike cotton ones which I always seem to notice. I wore them outside in 30 degree windy weather by themselves and they felt wind resistant and solid whereas cotton leaves hot/cold spots.,,,,I'm 6'3 and 200lbs and the large fit me perfectly and snug. All of the seems appeared durable but I don't know long term durability or wet performance yet. They appear to be better than cotton in every respect expect for price which is steep.

what is the difference between 2LW and 3MW patagonia merino wool bottoms? Ordering for my husband for dogsledding in Churchill Manitoba.
Asked by: rihapet
The Patagonia 2LW Merino bottom is 8.1 oz, and the 3MW Merino is 10.5 oz. In a nutshell, the heavier fabric is likely to be warmer. I hope that this helps.
