Itchy wool is a relic that cycling has thankfully left in the past – but modern merino wool very much still has a place in the sport. Castelli's Flanders Wool Long Sleeve Baselayer uses ultrafine-gauge merino wool fabric for supreme next-to-skin comfort, and to offer excellent natural moisture-wicking properties. Not only does the merino wool naturally pull moisture away from your skin; it also is able to absorb a tremendous amount of water before you will perceive wetness. And unlike synthetic cycling gear, the Flanders Wool jersey is antimicrobial and doesn't retain odors. You might even be able to get multiple rides in this base layer between washes.
Castelli rates the Flanders Wool Long Sleeve Baselayer for use in temperatures between 50 and 64 degrees Fahrenheit, but with appropriate layering techniques, it can be part of an ensemble suitable for much colder temperatures. Base layers are arguably the most important part of a serious cyclist's wardrobe: it's where the all-important moisture wicking and insulation begins. Without keeping one's chest dry, there can be no comfortable warmth. Start with a Flanders Wool Long Sleeve, then add mid and top layers as conditions dictate, ready to make adjustments as you go.
The form-fitting Flanders Wool Long Sleeve keeps drafts out, and the mock turtleneck provides extra coverage to your lower neck and upper chest. An extended tail ensures that your back is covered, even in an aggressive riding position. Flat lock stitching prevents any bulging or irritation at the seams.
Castelli's Flanders Wool Long Sleeve Baselayer weighs in at 159 grams. Try the feel – and natural performance – of a top-quality merino wool base layer, and you'll realize that there most definitely remains a place for wool materials in the modern peloton.
