Love these pants! more comfortable and more protection than jeans! i havent needed to wear them with the liner inside yet because even on our colder Florida days they have kept me warm enough. The vent zips on the front and back make for a nice cooler feel on warmer days. i wear a 36 in pants so i bought the XL in these pants. they fit nice and with the pull tabs at the waste i can tighten them right up to my waist. So far these pants are my favorite part of my riding gear!
