Product Customer Reviews

I must not have read the product description because if I had I would have not bought this bra. There is no padding in the cup area nor does it support well. I feel it’s somewhat see through.
Super comfortable and good support. Would recommend.
Product is as described. Comfortable fit.
Very nice. Good material. Good size. So I bought again
Very versatile, was a great support during pregnancy as it's non-wired.
As a runner I’ve always used proper running bras for good support. I decided to try this one and was blown away by how supportive it is. Totally gutted to discover that it’s since been discontinued - please bring it back.
Amazing value and perfect fit. Gutted they’re not available anymore
Great for price. Slight bounce but still comfortable. Only been used when doing short runs
Brilliant support
Great and firm fit. True to size! Best & cheapest sports bra I have ever bought. On the website at the mo to buy another for myself and daughters too!
Great sports bra, I’ve not ran my usual distance in this yet but so far it seems really good. Very generous around the chest, well made
Does what it's supposed to
Comfy supportive no bounce and no chafing so far.
My usual size fits perfectly. Good quality fabric, washes well. I’ll probably buy in more colours.
I've tried a few running bras and this is the best - and least expensive - one I've found. So much so that I bought a second, and came back today to try buying a third. Sadly they've run out in my size, so I'm leaving a review instead! It's a good bra and the material means it's not too heavy or sweat-inducing. Having the hook and rings to turn it into a sort of racer back gives more support and still feels comfortable, though it's a bit tricky to do up the hook until you've had a bit of practice. Top tip - make sure the hook is pointing the right way before you put the bra on! I definitely recommend this bra and *really* want to get another one when I can!

Additional Product Information
Composition
Back fabric: 76.0% Polyamide, 24.0% Spandex ; Main fabric: 68.0% Polyester cationic, 32.0% Polyamide ; Lining: 100.0% Polyamide
How is the maximum level of support of the classic running bra (level 5 on a scale from 1 to 5) guaranteed?
All our products are passed by our bust support test (measurement of the decrease in breast bounce when running) conducted in our laboratories. They are evaluated and given a rating from 1 (low support) to 5 (high support).Like all the KALENJI models, this sports bra was given a level 5 rating and is suitable for all HIGH IMPACT sports.*This sports bra reduces bounce by 37% compared with a conventional bra when practicing HIGH IMPACT sports.
What type of cups does the classic running bra have?
The Classic sports bra has 2 flexible single-thickness cups (no shell). The cup material, which is durable and fine, allows the bra to dry quickly.We also offer sports crop tops and bras with breathable molded cups.
How was this classic bra designed?
We designed a sports bra for optimum comfort and breast protection:As with all KALENJI models: * we do not use underwiring (risk of injury or of compressing the glands)* we keep the number of seams around the nipples to a minimum (risk of irritation)* we use components that wick away perspiration (this criterion improves comfort while also considerably diminishing the risk of irritation).
Straight or crossed straps?
The straps of the Classic running bra may be worn vertically, like a conventional bra. They may also be attached in the middle of the back, using a hook that connects the 2 rings. This frees up the shoulders and gives greater freedom of movement.We read your reviews of the previous version of this product and improved the hook: once attached, it will remain in place thanks to the safety catch.
What if it is too tight across the back?
If the cups fit but the chest strap is too tight, you can extend its length using the KALENJI BACK EXTENDER that is available in the following compatible heights: 38 mm: is compatible with sizes: 85D, 85B, 90B, 95B, 90A, 95A, 85C and 90C.57 mm: is compatible with sizes: 95E, 100E, 90D, 95D, 100D, 100B, 95C and 100C.
Product testing
SUPPORT: the support was tested and approved by testers in the DECATHLON laboratory. Each size was tested separately.PERSPIRATION WICKING: the perspiration wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it.WASHING: The washing and drying tests guarantee good stability (dimensional stability and colorfastness)
