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.

  • Excellent (100% Merino SS Baselayer Black)

    Pascal Gerritsen, Netherlands, 4.9.2018

    I wear size L but next time i will try XL. I'm 1.93 and 78 kilo. Jersey is L but bas will be XL. Top quality, always wear Rapha, but this is much thicker and it fits better.

  • Spot on (100% Merino SS Baselayer Black)

    Mark Botham, United Kingdom, 17.1.2018

    Had the l/s for a few years and it's been great. Don't know why but tried 2 other brands before going back to Isadore. It was the only one that fitted well, didn't itch and keeps me warm. You pay for quality.

  • Výborne (100% Merino SS Baselayer Crushed Berry)

    Matúš Hübler, Slovakia, 11.1.2019

    Nátelnik s výbornými termoregulačnými vlastnosťami vhodný aj na iné outdoorové aktivity, ako je cyklistika. Pri kúpe odporúčam vybrať o číslo väčší nátelník, vzhľadom na to, že je vyrobený z vlny a po vypratí má tendenciu sa zrážať. Prať len ručne!

  • Herr (100% Merino SS Baselayer Crushed Berry)

    Ulrich Ziegler, Germany, 26.10.2018

    Sehr eng anliegendes U.-Hemd, sehr knapp bei Gr. M/175cm/70kg, Evtl. minimal zu kurz geratener Rumpf, aber ich persönlich finde es super. Größe M der britischen Konkurrenz (R.) ist mir etwas zu lang, drauf sitzen mag ich nicht.. Also tendenziell eine Nummer größer, wenn man das racemäßige nicht so mag...

  • Mr (100% Merino SS Baselayer Crushed Berry)

    Robert Mitosinka, Slovakia, 31.8.2018

    Super kvalita aj farba. Velkosti su trochu nevyspytatelne medzi dlhym a kratkym rukavom ... M a M nie je celkom totozne.

  • GOOD bUT NOT BEST (100% Merino SS Baselayer Black)

    The best off :)

  • VERY GOOD PRODUCT, BAD CUT... (100% Merino SS Baselayer Crushed Berry)

    Christophe LE GONIDEC, France, 18.4.2019

    I'm very happy with Isadore signature jerseys! Size S fits perfect for me. So I decided to order 2 baselayers size S(one SL and one SS). They were suprisingly too small for me ; I had the impression to wear my child clothes! I exchange both for Medium size as Isadore Return and Exchange works very well. SL baselayer fits perfect but SS one remains too short in M and therefore very uncomfortable. Anyway, I'm happy with the first one. I wear it as often as I can. Nevertheless, I have to admit that I hesitate to order other Isadore articles because of this size/cut issue.

  • 100% Merino SL Baselayer - Too short! (100% Merino SL Baselayer Crushed Berry)

    Daniel C, Germany, 9.1.2019

    Nice looking, good quality, and probably good functionality. But a terrible fit! It is way too short! All my Isadore jerseys fit perfectly (XL for 194cm, 92kg), but the baselayer doesn't work at all for me. The baselayer is shorter than the jerseys, and as its 100% Merino, it's riding up on your back leaving your lumbar section exposed. I my opinion, baselayers should be could rather long, as they worn under the bibs. If you are rather short and/or don't mind your ass and lower back not being covered by anything but the bib, the baselayer might be ok. If you are tall and/or want the baselayer to cover more, stay away.
