Comfortable, no wire light material

Bought this Bra as it is a light material, no wire bra. The cup size is smaller than expected (for D cup size) but the strap fits comfortably under the bust. Would be a better fit for B or C cup with 34-36 size. Easy to wash in machine or hands. Material is good quality.

Running sports bra

very comfortable & good value for money.

Great value bra

My usual size fits perfectly. Good quality fabric, washes well. I’ll probably buy in more colours.

Good fit and great value

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!

Great supportive running bra

This is the third bra I’ve brought. They are soft supportive and very comfortable. I love the extra hook on the back that allows you to turn it into a racing-style back & provides additional support

Great buy

I love these. I needed the high impact support for running and these are perfect and great value. And, because they have the hook to join the straps, you can just unhook and ping off like a normal bra, no more getting stuck trying to get a sweaty sports bra over my head !

Product information

Main fabric

  • 32% Polyamide
  • 68% Polyester


  • 100% 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 practising 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 moulded cups.

How was this classic bra designed?

We designed a sports bra for optimum comfort and breast protection:Like all the 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 which connects the two 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.
