Men’s Long Sleeve Baselayer


Our Long Sleeve Baselayer is a pleasure to wear as a layer against the skin at both ends of the temperature spectrum. Because of the incredible breathability and temperature regulation of the MERINO + CARBON fabric, this piece will see you comfortable, warm and dry no matter what the season.

The beautifully soft, close fit of the garment allows for an optimum range of motion while running or on the bike. The slightly extended arm length accentuates this, ensuring that when you are on the drops there is no way through for cold air.

The versatility of the piece stems from the material. Carefully chosen for its natural thermo-regulation and enhanced wicking properties, the Merino blend actively lifts sweat away from the skin and transfers it to the outer layer of the fabric.  If you really wanted to test the odour resistant properties of Merino, you could sport the piece over multiple rides for days on end. Your lungs and muscles may feel the strain, but the Baselayer will still smell, look and feel great.

Nigel Gaskin, ashmei ambassador and GB triathlete, adds: “I have worn Baselayers before and they have felt thick and heavy, which often meant I was drenched in sweat in no time at all. The ashmei Long Sleeve Baselayer is so thin you’d not notice you where wearing it, yet I was surprised how warm it kept me. I have also used it at the gym. Normally I’d not wear a Baselayer on its own because it can look like you are wearing PJ’s, but, as expected, the styling is spot on.”

    Very good baselayer and comfortable on the skin. The fit is also good. Will buy more in future.

  2. Stephen stead

    Very thin ideal for running in

    This long sleeve top preforms better than I expected, as a base layer or as an outer layer. I’ve had plenty of 100% merino wool long sleeve tops before I purchased this one from Ashmei. The blend of fabrics preforms really well with temperature regulation in cold and mild conditions. The lightness of the material holds less water in wet conditions, and the non-odour properties make is an really attractive purchase. The cut and fit makes it very suitable for running in all conditions, although I would purchase my next long sleeve one size up than normal.

    Think all base layers are created equal? Think again. Once again ashmei work their merino/carbon magic & the result is a beautifully soft, stretchy top that feels too thin to be warm but proves toasty. The fit skims the body without being overly fitted & I can see how this will end up being a versatile purchase as the seasons change, worn under a gilet, light jacket or t-shirt. Trust me on this – you will want more than one: for running, cycling or just lounging around the house…

    Since I bought this baselayer I’ve always worn
    I use it for sport and not only
    It’s very versatile, has a very high quality and a very elegant design. These are characteristics of the Ashmei brand.
