Awesome! Comfortable and not baggy! But I took one size smaller. Check sizes
The clip at the top of the fly on the waist band, is very cheap and bends easily, to the point of being almost useless after only being worn twice.. A simple button structure would have been better. The bike shorts themselves are good and comfortable.
Thank you for taking the time to give us some valuable feedback Colin! I will pass this feedback on to the relevant people! In the mean time if you would like to change your pair for another product feel free to contact the store to organise a refund or exchange!

Amazing quality and fit at a great price.
Very comfortable and great price
Top shorts. Stylish and sturdy. Super comfortable.
The shorts fit well and are very comfortable. I shall be buying another pair soon.
Comfortable fit. Perfect for riding and less conspicuous at coffee stops. Front tab does flare out a bit which is a bit annoying. Similar to stock photo.
As described. Very comfortable and great wear.
I ve been using them witouth any issueas since day one, super cofortable
Awesome quality. I used it regularly on trails. I already bought 2 types of mountain bike shorts. I will definitely buy more if there’s new styles coming.
Solid quality, just a little too short for me I think. I'm 6'3 tall, anyone shorter the length is fine.
Comfy shorts that seem well made. Unfortunately I feel annoyed that they don’t come down to the knees as the images suggest. These look ridiculous when you have knee pads on as you get a gap between the top of the knee pad and the bottom of the shorts. So these shorts will be relegated to road cycling duties. If they were longer and covered the knees they would be great!
Very comfortable to wear due to the stretchy fabric. Great quality and seem to be wearing well. A 3/4 length version would be absolutely fantastic
Good fit comfortable material more pockets will be nice

Our tip: wear undershorts for added comfort!
At Rockrider, we recommend adding undershorts with a pad under your 900 mountain bike shorts. The undershorts fit discreetly under your shorts. We must say: it is certainly more comfortable with a pad. The 500 and 900 mountain bike undershorts are compatible with the 900 mountain bike shorts.
