The frogg toggs Mystic Wader is an adjustable wader for fly fishing. Constructed with a 4-ply nylon upper and 4mm double-taped neoprene booties, they're durable and protective when wading into the river. The Y-back suspenders adjust for fit, as well as the wading belt, and both feature quick-release locking buckles. Tuck essentials into the splash-proof zippered chest pocket or the flip-out security pocket and spend all day fishing.
