  Merino Long Sleeve Baselayer

  The jersey is a nice winter weight. It is form-fitting and comfortable against the skin. It seems to wick pretty well. Certainly a good add to my cycling kit.

  Very versatile and comfortable

  Really nice quality base layer, suits a wide range of temperatures, especially by varying the outer layer. Slightly thicker material than the short-sleeved merino base layers. I am normally a medium in Isadore tops, but I go for size large in merino baselayers and they fit well. Definitely recommended.

  Superb

  I'm 187 cm, 90 kg, on the thicker side. I ordered this base lyer in size XL and it fits perfectly. It's soft on the skin, no problems with the length of sleeves and my belly has a space for growing even bigger during longer rides with many pit stops :) Managed to catch one 50 km ride in it so far. Temperature ranged between 1-2 degrees Celsius with chilly wind (headwind in all directions, of course). Wore only this base layer under the Perffeto RoS 2 jacket and I was still very warm and even got quite a bit sweaty. Amazing item. Recommended.

  Fantastic Merino - truly a quality product

  I couldn't believe how nice this base layer is to wear. Apart from the incredible comfort, it is wonderfully warm and more than enough under the Alternative Eco-Fleece long sleeve with a light gilet on top, even down into the low single digits. I can't wait to test this in the properly cold depths of the Norwegian winter.

  I am 182 and 74kg, ordered M (I have everything in M from Isadore) and it comes Race fit. (if you want more relaxed, then go one size up). I use it for Hiking and Winter climbing as well. This is such a quality product from Merino, the best I have ever seen or used (I have a lot of them). Soft on touch and really warm and thick. The price is a steal, go for it!

  Superb

  I have a drawer full of merino thermals I wear both off and on the bike. Most are 150 or 180gram weight. This one is 250gram and is the best by far. The sizing is tight to begin with but merino does loosen up with time. Some have commented that these are expensive. I disagree. If you can find a 250gram merino top at a better price I would be surprised and of this quality definitely not. Chapeau Isadore!

  Comfortable and breathable

  Had my 100% Merino LS baselayer for a couple of years now, and it still feels very soft and comfortable against the skin. Mine did shrink a little after a few washes even after following the care instructions, so in future I might be inclined to size up. The Maritime Blue colour is definitely closer to the blue in the model photos, rather than the more purplish tone in the product image, but it's still a great colour.

  I wear several non-cycling merino shirts as base layers. This one is better: softer on the skin and form fitting. It is also thicker than the others, so I wear it on my coldest rides. I am 193cm/95kg and the XXL fits me perfectly.

  Comfortable but sleeves too short

  Just bought XXL (180/90) for Winter walks and rides, feels very comfortable und cosy. Unfortunately the sleeves are about 2-5 cm to short. Usually this is not a problem for me with other brands and the Ovada Deep Winter Baselayer Men in XL. Using the thumbholes helps a littlelittle bit. Please give some cms to the sleeves ;-), especially for winter.

  High quality merino

  I purchased a few of these long sleeve merino base layers. It's a high quality merino, which allows for some flexibility in temperature to stay comfortable (not too hot or cold), so I use this base layer when temperatures differ much between the start and finish of my ride. It's also very nice to have a beautiful blue instead of black or white. I'm 1.75 m and 71 kg, and purchased Large (which is a very comfortable fit, and still close to the body - Medium should be my size, but I prefer a larger fit for winter and have longish arms). As I have a number of these already, needless to say that I'm very happy with this great base layer.

  GOOD ADVICE

  Great base layer pair this with long sleeve jersey and Merino Softshell Jacket still warm in sub-zero conditions. Love the thumb holes nice touch. The advice is to buy a size bigger than your jersey size - i can definitely recommend this as even when using cool hand wash the item did shrink a little which is fine if you buy a size up. Highly recommended as usual with the brilliant Isadore gear!

  Best baselayer I have owned

  I have been really impressed with this base layer. It is a great fit, and super warm so far. I have been riding in 1 - 10 degrees and the base layer and a Gabba jersey have been a perfect combination. I really like the quality of the base layer and hope it last longer than my previous merino layer, from another leading brand, which disintegrated after a couple of years. Cstomer service and packaging are a joy also.

  Schlichtweg das Beste!!!

  Aufgrund der positiven Rezesionen hier habe ich mir dieses Unterhemd bestellt! Vom ersten mal Anziehen war ich schlichtweg begeistert! Tolles kuscheliges Tragegefühl und eine gut sitzende anschmiegsame Passform. Fahre bis -5 Grad 3-5 Stunden mit diesem Baselayer und der Isadore Jacke. Kalt wird es nicht! Der Schweiss wird fantastisch abtransportiert und das Körperklima wird durch Merino super reguliert! Verwende es mittlerweile auch zum Joggen, wandern und im normalen Alltag!! Ein absolutes musthave und mein Lieblingskleidungsstück! Wunderbar dass es auch in Europa zu (hoffentlich) gerechten Lohnverhältnissen gefertigt wird. Abgesehen von der Fertigung ist das Leiberl noch in einer anderen Hinsicht nachhaltig: Man braucht es nur alle 3 Wochen waschen! ! Fängt nicht zu riechen an! ! Wirklich ein tolles Produkt! Outstanding!! Ich: Rennradfahrer 10.0000 KM pA // 180 cm/ 82 kg = Large anliegend = Xlarge locker

  Best base layer you will ever use!

  This is a bold statement I know, however its absolutely true. These base layers are outstanding and have become my number one item for every ride, ski, walk and generally anything outside! Super soft, they wick moisture away from the skin immediately, they don't leave a bad smell and wash very easily. I have been washing them a lot and after 5/6 months they are still in great condition. They are probably the most popular item in our cycling club. Buy the bundle and then 3 of each because you will use them and your friends will want some too! Another outstanding product from Isadore.

  Ordered this as my UnderArmour made me feel the chill when it was around 5 degrees. So having seen this get top marks in a cycling magazine I thought paying a bit for a better quality product was the way to go. Simply, it is very comfortable & keeps the chill completely off. Much better than the UnderArmour. I know price is always a consideration, but you pay for quality. I cant recommend this highly enough.

  Light, Comfort & Function

  I have a few Isadore base layers now and I don't wear any other. The merino is soft and supremely comfortable. I always wear a base, even in summer (a vest), and these are excellent for wicking moisture away. They have no odour so you don't need to worry about the cafe stop. Wash them carefully (30 degrees maximum and use delicate cleaning agents) of course, and they stay like new.

  Veľmi pohodlné

  Skvelé merino, kúpili sme aj pánske aj dámske. Je priliehavé, takže nikde neprefukuje, po vysokej záťaži a vyvetraní vôbec necítiť pot, je hrubé, ale pri spotení je omnoho menej mokré ako klasické termotričko. Je trošku kratšie ako sme zvyknutí, ale zase nikde nezavadzia a úplne to stačí. Za nás skvelý produkt.

  Skvelé Merino

  Nemal som zatiaľ až toľko skúseností s merinom, ale toto je naozaj vynikajúce. Vôbec, ale vôbec neškriabe, naopak je veľmi príjemné na telo. Ani neviem, že to mám. Vôbec nesmrdí po niekoľko-násobnom použití čo je super. Jediný problém menší, ktorý som našiel je, že by bolo dobré spraviť dlhšie rukávy resp. ich vyriešiť nejako inak.
