Base Layer - 100% Merino Wool Midweight Long Sleeve Thermal

MERIWOOL earns its place by delivering merino's real advantages - warmth when damp, low odor over four or five days, a wide comfort range - at well under what the Smartwool and Icebreaker equivalents ask. At 250 gsm it is genuinely midweight, so it works as a shoulder-season and winter next-to-skin layer or a cold-camp sleep shirt. The catch is that 250 gsm is too much fabric for most three-season hiking; wear it on a climb above 50 degrees and you will be soaked and stuck with 283 grams of slow-drying wool. It is also heavier than any synthetic of equal warmth, and merino this fine wears through at pack-strap and hipbelt contact points faster than people expect from a shirt at this price. Note that the listing shows two conflicting weights, 283 g and 90 g; confirm the size you order. Skip it if your trips are summer trips.
