Product Customer Reviews

I’ve had a few sets of gloves from Decathlon over the last 5 or 6 years. This is obviously part of a new range, might need some temp guidelines. Feel great and work well with smart phones as the label segments. But can’t be worn far south of 10 degrees, lacks the wind proof nature of previous models.
The inner cloth has been excellent , I have used it while playing cricket and it has been keeping me dry by soaking the sweat from my body. It is easy to dry as well.
Product does exactly what I wanted as a base layer for cycling in cool weather.
Purchased this oversized to go over a running pack. Has done the job. Kept my shiz dry.
.
Excellent to work out, walking with chilly weather or wear under office shirt as base layer.
Very nice
It makes any of us to be very wet and feel uncomfortable and cold because of the sweat and cold weather. Completely the opposite as it should do. We have tried, different adults, and all with the same result.
Hi Zaida,
Thanks for your review - I'm sorry to read of your unhappiness with the product. This is extremely rare as the Keepdry 500 is one of our highest rated products. We have recently updated the design & the feel of the product, which you can see on the link here (https://www.decathlon.co.uk/keepdry-500-adult-white-id_8523895.html). If you're not satisfied with the product and it falls within our returns policy you can of course exchange or return it. I hope this helps and that one of our baselayers does the job for you.
Kind regards,

I bought this to do boxing training. gives you a little bit of spring and its a hugs your body feels good. But there is a lot of lables sticking out.
Hi Ruhel,
Thanks for taking the time to leave us your feedback on our base layer. The labels on the inside of this product at the bottom around the waste can be cut out before wearing. They are attached to the top with a small piece of excess material that can be cut away.
Yours sportively,
Joshua Gutteridge, Commercial Leader
Worn for a variety of sports - comfortable, fast wicking of perspiration.
I bought this for my father-in-law as he takes medication for his blood pressure and is constantly cold. He loves it and will not stop raving about how good it is.
Worn at Wembley, under my Pompey top, kept me nice and warm
Great for camping and outdoor activities.
Useful while you training and running

Why wear a base layer?
The base layer, also known as the inner layer, helps: . absorb perspiration and transfer it to the outside. The skin stays dry, so the body doesn't get chilled . retain body heat more effectively, particularly when the garment is close-fitting . form an additional barrier against bad weather . keep the playing jersey (layer 1) dry even when running hard. Playing with a technical base layer keeps you on the pitch for longer.
What our design team has to say
Attuned to our users' needs, we've crafted a garment that meets the needs of more experienced players for whom the pace speeds up when the game is fully underway, and who experience greater fluctuations in intensity. Your clothing needs to be ultra-breathable to regulate your body temperature during the more intense parts of the game. Your base layer also needs to be tight against your skin to keep you warm.
Breathability
To keep you dry and regulate your body temperature, Kipsta developed a breathable fabric that increases moisture wicking to the outside. A special mesh knit is used to ensure greater effectiveness in perspiration areas. The knit quickly wicks away moisture to keep you warm during exercise.
Temperature regulation
The combination of the fabric and technology offers excellent body temperature regulation so you can play hard without getting chilled.
Matching outfit
The range of available colors makes it easy to match with jerseys and shorts worn in training and matches.
