  Perfect extra warmth during spring rides or suprise rains

  This spring I don't think I've done a ride without having these with me, as soon as it either starts to rain or dips belove 10 degrees they add a convenient layer of extra warmth without taking up to much space in my pockets.

  admirable arm warmers !

  First arm warmers I've bought and they arrived just before our Club challenge 100 mile ride. They kept the early morning chill out superbly and the merino wool addition makes them very comfortable; in fact they stayed up and on all day with no sweat. Very impressed with the quality and hope other colours appear too !

  It irritates the skin.

  I bought this arm cover for my signature jersey. However, unlike jersey merino wool and the feel, it is tingling and irritating to the skin. I was hoping for a jersey-like soft merino wool, which is a shame.

  my first warmers

  After long reading of reviews and deciding what to buy as my first arm warmers, I've decided to buy these merino ones from Isadore. Now, I am convinced, that it was the best decision. They feel little bit itchy on the beginning, since it's 100% merino, but after few moments, the material seems very soft to arms. Wearing them on is not a fight. They insulate your arms very well, yet they breathe, when you need it. I really like them. Of course, they will not protect you from the rain, but I ride 99% of my rides in dry conditions.

  WORTH EVERY PENNY

  I absolutely love these arm warmers. They’re comfortable and they keep me warm on those chilly days. They really go great with Isadore jerseys. I usually pair them with either my Climbers jersey or Woolight jersey. Combined with a merino base layer , I can ride comfortably in the low 50s (F). Anything below that would require a vest or jacket. Compared to other high end brands, you really get your bang for your buck with this one.

  Superpower product

  With these arm warmers, your short sleeve jersey is now a long sleeve one! Still going strong 2 years from purchase and frequent use. A true must have for even a mildly serious cyclist.

  Perfect arm warmers

  Arm warmers are comfortable and warm. I'm using them not just for cycling, but for running also.

  Absolutely good buy!

  Wonderful warmers, made by Isadore in their typical high quality. Fitting well and spending just the warmth needed on colder days when you still want to use your short sleeve jersey.

  Ich habe jetzt beide Größen. Zuerst habe ich S/M geordert. Die passen in der Länge perfekt, sind aber schon sehr eng, obwohl ich eher dünne Arme habe. L/XL sind dann angenehmer, aber um gut 5 cm zu lang. Ich schlage sie oben um und gut ist. Die Funktion ist bei kühlen, frischen Bedingungen über jeden Zweifel erhaben. Ideal um stark schwankende Temperatur-Schwankungen während einer Tour zu kompensieren....

  Comfortable and versatile

  I didn't expect less from Isadore and that the fact these are made from merino. The fit is very comfortable and is much more versatile than any other of my arm warmers. These arm warmers can end up staying on for much longer as I/ the day warms up which is a good thing so I don't have to bother taking them off mid-ride. Based on my experience of my other kit, I reckon these will come in handy when I am deep into Autumn on those higher intensity rides when I need to concentrate on riding hard and the merino will work its magic to let the perspiration out whilst keeping me warm.

  Wonderful so far....

  Use these with the merino knee warmers. Fantastic temperature regulation, love the grey weave and look (reminds me of kit I couldn't afford here in Australia in the early 80s that people bought back from Europe). These with a jersey and gilet so far all I need for crisp mornings here in Melbourne. Don't smell from your sweat, stay in place very very well, current favourite bit of kit.

  Comfortable

  These knitted merino armwarmers are a real surprise for me. When i started cycling back in 1977 there was nothing else than knitted cycle clothing. What a difference! Isadore's armwarmers keep your arms warm but also dry because of their great breathing capacity. I am very happy wiith them.

  Great product for colder days !

  The merino armwarmers are a little warmer than the lycra ones (which also are great btw.). With these there's no need to fear colder days. I highly recommend this product.

  Simply the best

  My new favourite arm warmers. Superb tight fit and keep their grip superbly but above all they are just supremely comfortable and toasty in the early mornings and after work

  Top Ware

  Beste Qualität. Top Wohlfühlklima. kleiner Nachteil = der Abschluss am Oberarm rollt sich etwas ein.

  Amazing temperature control

  Just back from a weekend climbing in the Swiss alps and these were the best bit of kit I had. Lovely to have in the fresh early morning start,easily came off up the first climb and it was so nice to put these back on at the top when the air temperature suddenly dropped. They provided super warmth for the down but with no over heating at all! On one final climb it was about 28C in in the valley and as we climed the temperature began to drop slightly with a fresh alpine breeze picking up. Halfway up I put these on and continued to climb the rest of the way perfectly cool. It was the first time I have ever worn arm warmers on the way UP. They breathed so nicely and kept the chill out. I have not tested in the wet and suspect the lycra system might work better (I will report!) but in the dry I will not be using anything else from now on! Thanks Isadore for another great product that is now going to live at the front of my kit drawer.

  Great for cold and sun

  Wonderful and universal piece of equipment. Merino wool makes them work differently compared to other materials (sportwool etc) - they won´t let you cool down when wet/moisty and you can also use them as screens e.g to protect sunburnt hands. I tried and they didn´t heat me up even when there was +30 outside.

  my favorite for early spring and autumn

  these sleeves are thicker and warmer than regular spandex sleeves and keep fluffy warmth in the descents. merino is way easier to put on still sweaty sticky hands.
