Clothing Baselayers - Mens

Specialized Seamless Merino Long Sleeve Baselayer

As with it's short sleeve model, Specialized considers their Merino Seamless Long Sleeve Base Layer as the holy grail of base layers. Perhaps they're right, but that's rare territory. Still it is as cozy as your favorite pair of wool slippers, yet it transfers moisture like water going through osmosis. It's the perfect recipe for a cool-weather layer courtesy of its Merino and synthetic fabrics. The science behind it is pretty simple. The synthetic yarns pull moisture away from the skin and distributes it across a large surface area where it can be rapidly evaporated. No moisture buildup means that you won't experience any clammy chills as a result of dramatic temperature swings, and your skin, jersey, and jacket are going to remain dry in order to leave you comfortable.

The cut and fit drives the efficacy of the garment. If it is not form-fit to the skin, the fabric cannot perform properly. It has a moderately compressive fit and feel but isn't restrictive with it's seamless construction improving fit and eliminating chafing. The designers ensured that targeted stretch and support areas are built-in, ensuring it moves with your body while you're riding. This is how a great baselayer should be built, and despite it being a sleeve model, it has a lower neck for better integration with a jersey and outerwear. When you need to remain consistently warm and dry on chilly days, look no further than this cool weather staple.
