Designed with waterproof and breathable material, the Redington Sonic-Pro HDZ Fishing Wader was built tough for long days bushwhacking through the backcountry - it's held together with Redington's signature SonicWeld technology for puncture free seams. The HDZ model differs from the HD model because of the incorporated waterproof TIZIP zipper for ease and comfort on the water. Ample pockets create enough storage space for essential gear, and the ActiveFit styling means these waders will be comfortable for even the longest days in tough-wading waters. Tough, ergonomic 3.5mm neoprene booties with 4mm bottoms give you additional comfort and increased durability against punctures.
