Utility Pants
$497.00
Like your favorite pair of jeans – on steroids. Same as AD-1 pants but without the full-length outseam zippers. They offer the fit and comfort of traditional jeans-cut styling, combined with the rugged, all-weather protection of 500 Denier Mil-spec TLTex® fabric, making them an excellent choice for riding, as well as everyday off-bike activities. The pre-bent knees allow for freedom of movement and include shaped, removable TF3 or TF6 kneepads for added impact protection. Features include: Two front pockets with hook and loop secured flaps to keep contents secure, one back pocket, double seat and knees, a flapped front fly, integrated loop for optional hip pad attachment and a gusseted waistband with belt loops. Adjustable radial ankle tabs allow for secure fitment around the calf and lower leg and a gusseted crotch offers greater all-day sitting comfort. Great everyday, all-purpose riding pants. Available in Men's sizes 30-46, Regular or Long. Black or Grey. Choose TF3 or TF6 knee armor. Made in America

Which Pants? Darien vs. AD1 vs. Utility...Regular vs. Light
AD1 pants fit me a little better than Darien pants. Their rise is less, so the waistband rides a little lower, and it’s slightly curved, which I also like better. The AD1’s included belt is a 1.25" Aerostich money belt, versus the stronger 1.5" side-release-buckled belt on the Darien pants. And compared to the Darien pant the AD1’s knees are ‘bent’ a couple of degrees more, which is nice for bikes with a little more rear-positioned footrests. The radius of this bend is a little bigger, too, so there is a bit more space for knee pads. Darien pants fit and feel a lot like Khaki's or regular pants and AD1's fit and feel a little more like jeans.
Up to about 70ºf I wear my AD1 Lights over regular jeans or khaki pants. When it’s warmer they go over Aerostich cotton riding shorts…which we sew right here, too. The new Utility Pants fit like the AD1's, and have all the function, protection and styling of those, but without the full-length side-zips, belt, or reflective on the leg adjustment tabs. You can slip them on and wear them all day, whether logging hundreds of miles or just riding across town to run errands. Remove the TF3 kneepads and these super-tough pants are practical as everyday off-bike wear, too.
