Cheaply made. After tying the waist it ripped the elastic waste band. The shorts don’t ride well. Will be returning them
Used it once loved them
These are great shorts so good I’m going to buy a second pair. The only reason l didn’t give 5 stars is the sizing isn’t generous or I’m fatter than I think
These are reasonable shorts. I'm usually a L or XL and settled on L, but the cut of the legs of the outer short is so wide that I could fit another couple of legs in there! Comfy? Yes. Padding?: Does the job for my 1hr commute (gel would be nice, but that would cost more , I guess) Cut: Inner short is fine. Outer short is a bit like clown trousers. Washing: Seems fine after a couple of washes. I would recommend them tentatively, but probably wouldn't buy again myself because of the cut.
Good product, very comfortable, have been using for last 7 days, only some reflective material is missing
I wasn't expecting much from these but they are as comfortable as shorts that cost double, highly recommended.
I bought these for summer riding. I ride my hybrid bike for exercise 3 times a week but I do not want to wear tight Lycra cycling shorts. These are loose fitting and very comfortable. The inner shorts are a nice snug fit but are stretchy. The outer material is not stretchy but are loose so no need. The padding is relatively thin but more than enough for riding for a couple of hours at a time. Overall, these are excellent value for money.
Pocket is good however, if you have an IPhone 10 or anything larger, it doesn’t fit in the pocket and constantly feels it’s going to fall out
Good for the price, but no pockets at all - main disadvantage.
A very good concept. Dries quickly. Value for money
Initially this is not what i wanted but after purchased, wear couple of times I'm getting comfortable with this shorts. Padding is good for long distance cycling.
Thank you for your compliments regarding our ST 100 Mountain Bike shorts.
This shorts were designed to be value for money but the padding on the entry level ST 100 shorts have definitely proved its price point!

"It's true, cycling shorts are worn 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!" Sylvain, Product Manager
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.
