Natural Merino fibers to keep you naturally comfy

Product description

The comfort level of your ride is often in direct proportion to the effectiveness of your baselayer. With a Short Sleeve 100% Merino Baselayer, you will have the best natural material right next to your skin, wicking moisture away from your body during summer heat and winter chill. Merino also ensures the perfect level over insulation for cold rides. And you won’t have to worry about introducing your smelly 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

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.

    im around 78kg and 179cm tall. i compared M and L. Large is more comfy and looser. Medium fits really well, tight but still comfy. my built is muscular and i was afraid the medium would be tooo tight but its not. its just perfect. the material feels awesome, looks well made and the first ride in it was more then satisfiying. this will not be the last product of isadore.

    My first Merino wool baselayer; I don't want anything else:) Following other reviews, I have ordered a size larger than normal. Size L is just perfect: 1.86m/72kg.

    Light enough to wear in warm weather, but warm enough also to be worn in rather chilly mornings. Very breathable and odorless if you do multiple day rides. I followed the advice to take a size bigger. Took size L, I'm 186cm and weight 73 kg

    hatte urspruenglich grau bestellt - "leider" gab es nur noch golden oak. seit dem ersten mal ausfahren bin ich ziemlich gluecklich mit golden oak. werde noch ein grau bestellen sobald es wieder verfuegbar ist. komfort, optik, gefuehl - alles passt. bezgl. groesse: wuerde im zweifel zur groesseren variante raten. mein SS in L ist sehr sehr knapp. XL passt ohne, dass irgendwo ewtas flattert - laut tabelle wuerde ich mit 190cm und 81kg ziemlich dazischen liegen.
