Snug fit, warm and extremely comfortable. Great value for money

Great thermo and keeps you warm. Only used it twice in around 5°c and was perfect. Looks very small when you unpack it but it's very stretchy and fits perfectly.

This base layer is by far my favourite because it is so light and thin, but yet has an amazing ability to keep me warm on cold days. It hugs your skin but very comfortably. On days when we start out at 3 or 4 degrees and it may get up to 10 or 11 degrees during the ride, it keeps you warm but doesn’t make you too warm as the temperature rises. It also wicks sweat nicely. I now have 3 different base layer jerseys made of the same material, they are so good.

Great winter under layer. I bought my first one last November and was so impressed that I had to get a second as it’s that good.

I definitely recommend. I have wool underwear and this one, with they material it's very nice on my body, material very thin and strong.

Warm

Il est très beau, mais il est extrêmement petit. Ma femme mesure 1,80 m et 110 kg et c'était trop petit pour elle. Il est également accompagné d'un avertissement indiquant qu'il faut faire très attention en l'enfilant pour ne pas endommager le tissu.

Great fit very warm does a great job when riding in very cold weather

Form fitting and warm perfect for on the bike

love your products and love your prices even better.

Il s'agit d'une couche de base, pas d'une chemise que l'on porterait seule ; elle a un seul but, être cette couche étanche qui retient la chaleur. Je dis cela parce que la première chose que j'ai pensé en ouvrant le paquet était qu'il n'y avait aucune chance que cette couche soit adaptée, elle semblait extraordinairement petite, je pensais honnêtement que je ne serais pas capable de l'enfiler et encore moins de la porter. Mais j'avais tort. Oui, c'est très ajusté et serré ; c'est à peine si la peau est serrée, mais la matière bouge avec vous et semble étonnamment naturelle. Je pouvais également sentir immédiatement la chaleur qu'il emprisonnait, et ce de manière positive. En raison de l'étanchéité et du tissu, je dirais qu'il est un peu plus délicat que d'autres couches de base que j'ai, mais le prix valait la peine d'être essayé. Pour référence, je mesure 1,80 m et je pèse 1,75 kg ; en utilisant le tableau des tailles, j'ai commandé un L/XL et il me convient. Sachant ce que je sais, j'aurais peut-être pris une taille au-dessus, mais, encore une fois, il me va comme prévu. Si vous cherchez une couche de base, c'est un bon choix, mais sachez que vous serez surpris par la taille.

Perfect fit and keeps you warm with good moisture transport

These are great. Super snug fit. Arms are plenty long to account for in the chcling reach position.
Never got too hot, certainly didn’t get cold.
Excellent product, great value

Very good fit for me. I am 1.95m tall and good length on torso and the arms.
Very warm in cold British conditions and very comfortable.

My go-to now for really cold weather. This has the high collar, so better for low 30s and below. Handles sweat well.

The quality of this base layer is excellent and it wicks sweat quite well. Down to approx 8C, this base layer with a winter jacket is perfect and for 3-5C,add a winter jersey as well. In terms of sizing - I'm 177cm tall, waist 81cm and 72kg and L/XL size is perfect. Make sure you check the size guide, however.
Overall, I'm very pleased and pricing (winter sale) was perfect.
The order process and delivery was excellent ... although for UK based customers, be careful of values (to avoid import duty).

super!

Im not a cyclist but I was looking for good base layer for work in the winter time. I trim trees for proper clearance on power/utility lines and this shirt by far is the best base layer shirt I have ever owned!
I got this shirt after Christmas 2021 or 2022 for a great price of $18 and have returned today to shop for another base layer shirt of which i will not wait for another price drop i love the material so much I will pay what they ask as of today. Thank you ekoi for making such a great shirt even for people like me who do not cycle but want great thermal protection why working a job.

Amazing product, it makes me feel me warm without being too hot.

The Under Jersey EKOI Perf THERMO EVO High Collar is truly a game-changer for any cyclist looking to elevate their cold-weather riding experience. From the moment I put it on, I was impressed by the perfect fit. The fabric is incredibly soft yet provides just the right amount of compression, giving a snug, second-skin feel without being restrictive. It’s form-fitting in all the right places, ensuring that the jacket or jersey you wear over it doesn’t ride up or bunch, allowing for complete freedom of movement.

What really sets this piece apart is the high collar design. Not only does it provide extra warmth around the neck, but it also blocks out wind effectively without feeling too bulky. On cold morning rides, it made a huge difference in keeping me warm and comfortable. The Thermo fabric does an excellent job at maintaining body heat while also wicking away moisture, so I stayed dry and never overheated, even during more intense efforts.

The quality of the materials is top-notch — it feels like a premium product that will last season after season. The stitching and finish are impeccable, and it’s clear that EKOI has put thought into both performance and durability.

The moment payday comes around, I’m definitely buying more of these! Whether you're cycling in cool weather or just need that extra layer for a more comfortable ride, the Under Jersey EKOI Perf THERMO EVO High Collar is a must-have. It’s worth every penny for the warmth, comfort, and performance it provides.

looks and works great under a short sleeve jersey, especially when temps change during the day
