Product Customer Reviews

for affordable shorts, very comfortable and practical with their phone pocket.
SIZE PROBLEM, perfect size in L but the thighs don't fit at all... really tight
Very good model, the sizes are good pockets for the phone very well placed on the top of the thigh. Too bad it no longer exists
Nice quality
The product is slightly loose as expected. I'll be careful on picking the right fit for me. Maybe the size does not match with the common sizes when it comes to clothing. I bought medium but seems to be larger.
Excellent

Cycling shorts, the mountain bike rider's kilt
Don't forget: you wear cycling shorts without underwear.Why?Wearing underwear risks causing irritation.Your skin can rub against the seams and elastic of your underwear.Chafing, shearing, all combined with perspiration (heat + humidity)... this is quite the recipe for infections. That is why we design our shorts with anti-bacterial pads.Dare to wear shorts without underwear!
Our care tips
Machine wash inside out on a synthetics cycle at 86°F. Do not use too much detergent, and do not use fabric softener. It is best dried on a hanger in a warm, well-ventilated place.
