Giordana Wool Blend Short-Sleeve Baselayer - Men's
GiordanaWool Blend Short-Sleeve Baselayer - Men's

Classic wool.

Thermal jersey season is upon us, as is the time honored tradition of dusting off our cold-weather gear and assessing our needs to comfortably survive another winter of training. If you don't have one already, Giordana's Men's Short-Sleeve Wool Blend Baselayer should be at the top of your list. It's made from Mimosa fabric, a blend headlined by time-tested merino wool and incorporating nylon and spandex to keep you warm, comfortable, and dry.

Merino is a cycling staple that may no longer define the top racing jerseys and shorts as it did when all bikes were steel and cassettes were nowhere near the double digits, but there's a reason we continue to turn to it when the weather turns toward winter. It's breathable, it's the original hollow-core fabric, it stays warm if it gets wet, and it's naturally odor resistant. Every material used in cycling kit breathes and chances are good that you'll be wearing an anti-weather top in inclement conditions, so the real standout qualities for wool are the way it insulates and resists odor.

There's a pile of synthetics in the base layer industry described as hollow core yarns, and wool is the reason why. They're all trying to mimic wool's ability to trap countless tiny pockets of air in order to create a microclimate of warmth. It also stays warm if it gets damp, so you won't pay as steep a price if you over-layer and overheat during winter climbs. This timeless material is supplemented with nylon, which holds its shape and offers more support than wool, and spandex, which helps the four-panel construction disappear under mid and outer layers by stretching as appropriate.

Base Layer Performed

  • Fit: True to size
  • Size Bought: Large

I wore the base layer the first time on a 90 mile ride that started in the mid 40's and finished in the low 70's. Under my summer kit with arm and knee warmers the Giordana wool blend base layer performed very well through out the entire ride. Only my extremities felt the cold start.
