The Best Bra I've Bought So Far

It is very comfortable and fit nicely (I used this website to pick the size). This bra is put on by pulling it over your head so would be difficult to put on if you have difficulty lifting your arms and you need to watch long hair with the zip when putting it on but it dose it's job excellently. I was surprised at how easily I was able to run once wearing this and it feels nice to wear once you take the tag off. This bra doesn't really compress your chest or make it look much smaller (or at least it dose not for me). I have and will continue to recommend this bra as it dose its intended job well.

Reduces bouncing

They seem to vary from when I buy them . There still comfortable wear. I’m a 36c so not small. Around Manchester marathon in it last year and do Trail and road runs in it so suits me for running. No chafing under the breast area. Overall a good bra

I was around a 38/40C when I started wearing this bra just under a year ago. I'm a little smaller these days (dropped a dress size) after a year of running and it still just about fits. Its perhaps not as firm as it was - but it's been worn 3 days a week for a year, I think that's normal for a bra to stretch over time. I've come back to buy another one as I'm going hiking for a week and honestly this is my comfiest bra for any form of exercise.

Prompt delivery

Absolutely nothing wrong with the product for the price but I had to return this item as I did not like how it looked on me. Prompt delivery and very easy to return, refunded quickly too.

Great running bra

I bought this as I’m getting back into running but my pre-lockdown bra are all too small. Really impressed by the fit and quality. Highly recommended.

Best running bra ever!

I am a small lady with a larger bust and this is the best running bra I have ever bought. I have spent a lot of money on more well known brands and none of them provide this level of support. I have 3 of these and they are great for higher impact sports. They wash well and last ages too. Definitely recommend.

Not made for running

It says in the title of the product that it's a running sports bra so I assume high impact or at least medium impact? But no... There is no support - it's barely light support. It's actually a really nice bra but it does not work for running. Plus even though I followed the size guide, it's a little small for me.

Zip doesn't undo all the way

I ordered this front fastening bra as I have trouble getting sports bras over my head or doing them up at the back due to a frozen shoulder. Unfortunately the zip on this doesn't undo all the way so it was a non-starter for me. It looked like a good bra for the more able bodied.

Snug fit

New to running and found this a bit snug - think you should order bigger if you're an in between/ undecided

Style & Support in one!

I was apprehensive, as I usually am, about buying this sports bra and items alike. I decided to go for it, hoping it would be easy to put on, unlike my Shock Absorber bra, which incidentally is brilliant, but difficult to clip up. Well, this one is super, super easy. Just unzip the front part, pop it over your head and zip up, done. I am a 38DD, but this was only in the 38D I believe, but it fits perfectly. It's not super tight, there's ever so slightly a give as I run on the spot to test it, haha, but nothing major, as I felt my bust was supported. I'm a decent 16/18, more weight around my tummy and hips, just to give you an idea of size. I've done beginners stretching, cardio etc and not aware I had it on. Go for it ladies.

How is the maximum level of support (level 5 on a scale from 1 to 5) of the zip run sports bra 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 crop top was given a level 5 rating and are suitable for all high-impact sports. *This running crop top reduces bounce by 36% compared with a conventional bra when practicing high-impact sports.

How was this zip running bra designed?

This sports crop top has been designed for optimal comfort and breast protection: Like all the KALENJI models: * we don't use wires to avoid injury and compression of glands * we minimize seams around the nipple to avoid chafing * we choose fabrics that wick away perspiration to optimize comfort, but also avoid chafing.

How was the zipper of the zip running bra designed?

We developed this running crop top with a zipper at the front for easy dressing: For the larger cup sizes, you only need to pull up the zipper after having slipped the crop top over your head because the crop top will already be in place. The zipper does not open all the way to the top to protect the skin between the breasts: this design reduces friction in this area that can be sensitive when running.

What type of cups does the zip bra have?

The ZIP running bra has 2 flexible molded cups. They were designed in a special ventilated fabric (3D mesh) that ensures maximum breathability. Our range also includes crop tops and bras with non-molded cups.

Choosing the right size for this zip bra

We developed this running crop top in several cup sizes to suit different body shapes. Each standard size (M, L, XL etc.) is available in several cup sizes. For example, the size XL is available in a C/D and E/F cup. (XL = size 38) This type of fit, combined with elasticated materials, offers support that encapsulates the breast rather than restricting it. Check the "Choose the right size" guide to find your size.

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)
