Bib shorts were our first great epiphany in cycling comfort. Our second great epiphany in cycling comfort came when we acquired our first Merino wool baselayer. No other garment in our arsenal had as much power to keep us warm on chilly days while still possessing a comfort range that allowed us to wear it when the mercury rises throughout the course of the ride.The Castelli Merino Wool Long Sleeve Zip Neck Baselayeris cut from almost impossibly soft Australian Merino wool. You can be excused for thinking Castelli cut this from Cashmere, but it really is Merino. The zip neck will keep your neck warm on chilly rides while offering a very cool Euro look should you choose to use it for apres-ride wear. And because wool won't hold odors no matter how hard the race was, you could wear this to the podium presentation without offending anyone.While not truly form-following, it does offer a tailored cut that won't cause it to bunch up underneath your jersey. The flatlocked seams ensure your comfort and the durability of the garment. Flocked Castelli labels appear at the neck and lower back to show off your style.The Castelli Merino Wool Long Sleeve Zip Neck Baselayer comes in Black and in six sizes from X-Small through XX-Large.
