OutSmart™ Insect Shield® Wading Pants have an odorless EPA-registered bug repellent bonded to the fabric to fend off mosquitoes, ticks, ants, flies, chiggers, and midges (or no-see-ums, as they’re called in some parts). The UPF30 two-way stretch fabric blocks 97% of the sun’s harmful rays. Designed for wet wading, the quick-drying and moisture-wicking bluesign® material is made following an environmentally friendly process. Pants feature an elastic-back waist and articulated knees for complete range of motion, adjustable cinch-leg hems to seal out crawling bugs, and zip-close pockets on the front and back. In stone. Nylon/spandex. Washable. Imported.
