Extremely light!

Everything the description says is true! Light, soft fabric, super riding experience . Couldn't believe it was so good. I'm 190cm, with 108 cm hip the XL was perfect. I'll buy another one for sure!

Read the Size Chart

I usually wear a size 30" pants. I am an XS in all other 7mesh products. Other reviews said to go up one size and the size chart indicated that I should get a S. The S fit me perfectly. Wearing these on my gravel bike under my Farside shorts is far more comfortable than wearing my road bike bib shorts.

Light and airy

Usually Med/large. 5’10” 85kg. Ordered L and fits well. Good thing fabric is stretchy! Keeps things in place. Very well made. Definitely helps keep the undercarriage cooler without the chamois in areas that is not required. I find it performs just fine on med gravel rides and just as well on longer mtb rides because your out of the saddle more often.
