The Dynafit Elevation Longsleeve is a men's merino top from Dynafit's Elevation line, the mountaineering family, knitted from a blend of roughly 83 percent merino wool and 17 percent polyamide. The synthetic share is there for a reason: pure merino at this weight would not survive a pack strap, and the polyamide reinforcement at the shoulders is where that wear happens.

• Merino and polyamide blend: around 83 percent merino for warmth and odour control, 17 percent polyamide for the strength merino lacks.
• Reinforced shoulders: polyamide is concentrated where pack straps abrade the knit, which is the first place a wool top fails.
• Elevation is the mountaineering line: intended for long days on mixed ground rather than for racing.
• Odour resistance over several days: the practical advantage of merino on a hut to hut trip where nothing gets washed.
• Warm when damp: wool keeps a usable part of its warmth after it takes on sweat.
