Slammer Socks are made of durable Tyvek® material, back supports in stainless steel, lightweight fiberglass rods, Spring clips and can be used in any weather condition. While being transported between hunts, a bundle of about 150 Slammer Decoys will take less space than a single 6-slot goose bag filled with full-body Canada Goose decoys. Aside from realism and effortless wind motion in the field, Tanglefree now offers zippered Slammer Sock bags that provide easier use in the field and off-season protection. With 5 different Slammer Sock goose species, not including the economically priced headless Slammer Socks, there is a sock available that will allow you to fool one of the most difficult birds to decoy.
