Hello Devina,

Thank you for your feedback on this warm light winter running t-shirt.

See you soon in one of our stores or on our online platform !


Great buy

Loved my purchase. It runs small, I usually wear a large but needed an extra large. One of the best running gear I’ve owned. Perfect for a late fall/spring run

Great quality and very practical

So far I’ve tested it as a top layer for temperatures +3C ~ +7C and it works a treat.

A really good top

It is warm and has good features. My only criticism is that it has a tab to hold back one side of the neck but not the other. That’s a minor point though. The hand covers are good and there is extra warmth at the right points. It’s comfy with a t-shirt underneath. I’m using it a lot.

Bang on running top

Cool weather outer or cold mid layer. Good fabric, thought mits would be a faff but they're ace. Watch window works a treat, saves mucking about with cuffs. Pricey, but really decent top. 4 stars as a hood would have made it perfect. Just me being picky haha

Perfect cold weather Training Top

The material quality is really good, tried it on a few early morning cool runs and it kept me warm at the start but i didnt overheat when i got into the swng of it so i imagine this will be great for winter long runs

What a great top!

I bought this a few weeks ago and what a great top! It looks great and is really comfy. I am only using it for walking though so can’t comment for running purposes! The top is incredibly warm though! I would highly recommend!

Wish I'd found this site before so good to find dedicated running top

Great *****

This is brilliant. Ideal for the temperatures stated. Happily ran in this without even needing a base layer even in sub zero temps

Good but not that warm

Great shirt. Nice fit and super comfy. I really like the watch window, which works, and the parts that cover your hands. Downsides - not warm enough to wear at -5C as advertised, maybe to 5C, also the front pocket is useless as it is so tiny. Hence 4/5 stars.

Kip run shirt.

Great shirt,light and comfortable. Good for keeping the wind out when it’s colder.

Perfect winter running top

Can't recommend this enough, they've thought of everything. Saves me wondering whether to wear gloves or not! Only small adjustment would be to have a bigger pocket which could fit something more than a single key, but otherwise great. Have since bought another one!!

Additional Product Information


Main fabric: Top ; Yoke: 95.0% Polyethylene Terephtalate, 5.0% Spandex ; Front waist fabric: 88.0% Polyethylene Terephtalate, 12.0% Spandex

Temperature control

Regulate your body temperature with the ingenious double zipper. Lower the zipper as far as possible for maximum opening. A magnet is hidden under the fabric to hold the zipper open.Open the 2nd zipper upward to let air in and keep your neck warm at the same time.The zipper is offset to avoid rubbing the glottis.

Built-in mittens

Forgetting your gloves or not knowing where to put them when you're hot is in the past: The Kiprun Warm Regul has thumb holes and built-in mittens. These features will protect your hands from the cold according to the ambient temperature.And when you are warm enough, you can roll up the mittens and thumb holes.

Warmth and breathability

Made with waffle fabric, this top keeps you warm while also quickly wicking perspiration away. It protects from the ”freezing” effect when it gets cold (feeling of cold when you perspire). We have also included a mesh component under the arm and in the back for even better perspiration wicking.


We have added an attachment for the red flashing running light (reference:8394633) on the arm to clip the light on when running at night. To find this light on our website, copy the reference 8394633 and paste it into your search engine.

Directions for use

Ideal for temperatures between 23 and 41°F: You can wear the Kiprun Warm Regul jacket as a 2nd layer with a T-shirt underneath. For temperatures below 23°F: You can add a 3rd layer, such as the Kiprun Warm Regul or Kiprun Rain jacket.
