Powered by the next generation of sonic seaming technology, the Hodgman® Aesis™ Sonic wader utilizes Sonic 2.0 technology to create double sonic welded seams, which eliminate thousands of stitch holes. Each seam is reinforced with waterproof seam tape for ultimate leak protection, ensuring water stays on the outside of your wader where it belongs.##We know you’ll be in and out of drift boats or climbing river edges on your mission to catch fish, so we utilize 5-layer construction on the leg and seat for exceptional durability and puncture resistance. Additionally, we eliminated inside leg seams in high abrasion areas while still allowing articulation in the knees for stellar range of motion and mobility.##The wader upper incorporates 4-layer shell fabric for added breathability where you need it most, and features a Durable Water repellent (DWR) coating to shed water. A Riri® waterproof center-front zipper makes the wader easy to get on and off plus provides optimum ventilation.##Convert your wader to waist height without removing your suspenders via the drop down system for fishing in warmer days. Microfleece-lined hand warmer pockets utilize YKK® water-resistant zippers and an internal flip out storage pocket is included.##Comfort is key for long days wade fishing, so we use anatomically correct left and right booties for a comfort fit. Each stocking foot bootie utilizes 5mm thick neoprene to keep your feet warmer in cold water. ##This wader also accepts the Core INS removable insulation system so you can transform your wader for cold or warm weather wading (sold separately). The liner zips in to create an all-season wader.
