I purchased the pants on sale and after trying them on decided these might be helpful. I was sceptical about sending more $ on top of the cost of the pants but these are worth every penny. The system they use to fasten them is brilliant and very sturdy. I haven't had a problem with any of the velcro holders failing and don't see how they could. They don't slip at all once adjusted and keep the pants in place throughout a daily 32 mile commute without any discomfort. I don't know they're on until I stop riding and change clothes. The pants don't have a waist adjustment system so if they don't fit perfectly, they could easily slide down. Add to that that most cycling gear is made of slippery materials and these are a no brainer. Thanks to Showers Pass for another well thought out product.
When I got these bike shorts and put them on, I was impressed by how comfortable they were. I went for a 40-mile bike ride to try them out. I'm very happy to say that they were very comfortable throughout the ride. I'm really glad I bought these shorts and will be getting more of them in the future.
I have been wearing Cento bibs exclusively for several years now. The cento bibs have the most padding, 10 mm rather than 8, of any Assos model which I prefer. Also the straps on the Cento model are particularly wide and comfortable. The evo are a noticeable improvement over the s7. The front kudu pocket is a lycra type material rather than fabric, the padding is black and the straps even better than the s7, which themselves were excellent wide and comfortable. Note that the sizing is based on height and not weight or waist size. The bibs fit better if not bought larger than recommended, the padding will seat, position better. I'm 5'7 and medium is the recommend size for me and fits me better than large (which I also own). Although the s7 are still being sold and are a bit cheaper, I feel the evo are worth the additional cost. When Assos makes improvements, the improvements address technical issues and are not simply cosmetic marketing.
