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 nice baselayer indeed! Stays as warm as a high quality full merino baselayer but feels less damp and is certainly quicker drying, plus the look and feel of the fabric is first class. Great fit as well and looks to be very durable. I’m spoilt now..nothing else will do!

    Thin , stylish and very comfortable whilst not restrictive in any way.
    Almost too good to wear for running, great for casual wear too.
    Up there with the best!

    Bought this at halfprice on ebay in late November as they didn’t have XL in red on this site at the time, needed some baselayers for winter riding.
    Great baselayer, when you 1st put it on you think its thin & how is it going to keep you warm but it does beyond expectation, fits well (44″ chest) with it just being slightly to long in the arm on me (5′ 8″ ) but not really a problem. Will buy another if I can get some discount on the Challenge 31.

    As a long-term user of Ashmei gloves, running jacket and shorts, I don’t know why I’m surprised that the long sleeve baselayer slides on like a glove. It somehow manages to be snug and comfy – neat little touches like the proper cuffs hug your wrists unlike some of the competition – without being skintight and making me feel body conscious. Good work team! I think Dave Pratt’s comment is right, one probably isn’t enough…

    Great baselayer! Thin and comfortable. Just what I was looking for to keep warm on this winter’s training rides.

  6. Valentino

    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.

  7. David Pratt

    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…

    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.

    Very thin ideal for running in

  10. Steve Cushing

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

ashmei jerseys have an athletic cut. The fit is close to skin, but not skin tight, and uses a high stretch material which will adapt to your body shape.
