does not stay up properly

Not really functional as constantly slip down nothing to secure them at the top. Not really fit for purpose.

Cycling tights

Perfect size and good material

amazing quality for the price!

Only 4 stars for me because i do find that they are a little see through (especially in direct sunlight) so that is something to bear in mind. I wear mine in spin classes and they perform just as well as 'branded' tights double the price. I have just ordered my second pair and would definitely recommend.

No more saddle sore

Excellent product. True to size fit. Washes well. No more sore ******

Ladies Cycling Bottoms

Comfy with generous padding in the correct places.

Very comfortable.

These are great for wearing at the end of summer, when it's just that little bit too cold for shorts. Really comfortable and value for money.

Pad in wrong place

The cushioning pad is too far forward and therefore doesn't cushion

I'm sorry to read that the pad is not correctly located. 
If you are not happy with the comfort it should offer, please feel free to return it to us for a refund or an exchange with your receipt.

Really comfortable.

I've used these several times now. 30 to 50 km rides each time. Very comfortable on the saddle. Nice padded chamois without looking like you are wearing a nappy! Great fit and they look nice. I love the navy colour.

Advice from the team

Product manager Delphine has a few tips for you: "For mountain bike touring, choose a hydration backpack. It is the perfect option for staying hydrated without stopping. With both hands on the handlebars, you can more easily get through challenging areas. And don't forget to wear a helmet and long gloves for safety. To prevent scratching your legs, cropped tights are a good compromise. One last accessory can come in handy: puncture repair spray."

Our tips for the mid-season

In the mid-season, feel free to wear these 3/4 mountain bike cycling shorts underneath shorts to protect your thighs from vegetation and weather changes.

How to improve your comfort in the saddle

For improved comfort, we recommend: 1/ Investing in cropped bottoms or shorts with a built-in pad to avoid irritation and chafing. 2/ Take care to choose a saddle suitable for women's bodies. The ST 100 and ST 500 saddles are available on the Women's Rockrider mountain bike. But also as spare parts. 3/ Add a gel seat cover to your saddle. They are compatible with the Women's Rockrider saddles and make you more comfortable during your MTB tours thanks to their spongy texture.
