Our tips for the mid-season
In mid-season, you may wish to wear the mountain biking cropped bottoms underneath shorts to protect your thighs from both the weather and plants or brush on your trail.
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.

Material wasn’t as good as my previous pair
Used for 2 to 8 weeks
Great product for a great price when I bought my first pair last spring! And that pair lasted about 18 months of weekly spin classes. Then they finally wore through (where they catch on our type of spin bike.

So I rushed to Decalthlon to replace them only for them to be a disappointment. The amount of elastane in the fabric is less so the are not tight enough on the tummy and fall down. They also succumbed to the friction within 3 wears!!! Very disappointing!

Please please please change back to better fabric.
