A hot weather baselayer to keep you cool

Product description

Finding the right baselayer for your ride conditions will enhance your level of comfort on every ride. For very hot days you might be tempted not to wear a base, but your body can benefit from the help the right baselayer can offer even in hot, humid weather. Making use of the natural characteristics of Merino wool, the Sleeveless 100% Merino Baselayer moves moisture away from your body to allow it to cool you naturally. And you won’t have to worry about introducing your noisome presence into a coffee shop since the Merino offers an odor resistance to help you from alienating your neighbors at the next table.

  • Excellent moisture wicking properties
  • Easy to care for with cold water washing
  • Designed by Martin Velits using his experience from the pro peloton
  • Made in the E.U.
  • 100% Merino wool

All our baselayers act like a second skin. Extremly slim fit cut with extended back side for lower back protection. Whatever Isadore jersey size you are used to wear, this baselayer will certainly fit you in the same size. However if you prefer more casual fit, we advice you to choose one size bigger than the Isadore jersey you are used to.

    Base layers have always been a struggle for me. I could never find one that offered the comfort and temperature range suitable. This has all changed with Isadore. This base layer is perfect, with genuine comfort in a wide range of temperatures. Treat yourself to exceptional quality and comfort.

    Used my new sleeveless base layer today - together with my new Signature jersey - on a 2 hour spin. Very comfortable, nice fit and no annoying tightening under armpits when on the drops. Can recommend jersey and base layer.

  • Incredible bit of kit

    Ed Newey, Switzerland, 27.7.2015

    I have now ridden with this in cooler conditions and in baking hot sun. it is amazing how well it performs in both environments. in cooler conditions the wool blend is cosy and just takes the edge off. This weekend on a hot sun baked, brutal mountain climb it wicked the sweat away and kept me extremely comfortable. At the top the temperature fell drastically. I zipped up, wool arm warmers on to begin the descent and it was back to cosy time again. Ive bought 2 shortsleeve layers (will get 1 more when restocked) and will order a long sleeve for the winter. One guy on this ride had the long sleeve on and even on the climb going into cooler air he found it worked beautifully. and on the train home we didnt clear the seats around us... Another fabulous product from Isadore
