TrespassMen's Passcode Insect Repellent Stretch Hiking Trousers

Are these water and wind repellant? Thanks

hi, is there a size guide? L M Inormally buy size 36 waist and 30 leg,

What size waist is the xs/s?

Do these trousers have the anchored Hem Adjusters in the ankles? (Elastic cord with toggle that lets you secure the ankles)
