EvoShield is the world’s first and only CUSTOM-FORMING RECOIL REDUCING SHIRT and reduces recoil by at least 80%. Instead of using a thick, awkward, soft pad to attempt to absorb only part of the recoil force, this system spreads the recoil out over a solid, custom fitted shield resulting in far greater effectiveness and greater comfort. The moisture wicking, compression fit shirt has an integral shoulder pocket for the EvoShield recoil pad. The Evo Shield pad comes to you in a vacuum sealed foil pack that keeps it completely pliable. Once the foil pack is opened the pad is placed into the shoulder pocket of the shirt while worn and it will gradually start to harden. Custom form the recoil shield to your shoulder and use your rifle or shotgun to form your natural gun set into the shield for 5-10 minutes. After 20 minutes, the RECOIL EVOSHIELD is permanently formed to your shoulder and natural gun set. It will then cure and harden to form an extremely effective custom fitted recoil shield for your shoulder. You now have a custom fitted pad that will completely shield your shoulder from recoil. Pad is made from a fiberglass resin that cures when exposed to oxygen. It is covered with a soft mesh cover which gives it a comfortable feel and holds it in place in the recoil shirt pocket. The dual-process compression shirt keeps the body temperature regulated in all weather conditions. This system improves accuracy by giving a consistent gun mount using your permanent gun set formed into the pad, and comfortably protects by reducing felt recoil. Can be worn alone or as an undershirt according to shooter preference. Has been proven effective for everything from large caliber magnum rifles to shooting over 1,000 shotgun shells per day for several days in a row. This thing works! Whether you live for the shooting range and competition, shoot heavy magnums, enjoy hunting in the fields, or have an injury to protect, the EVO SHIELD will give you the pain free comfort and endurance you have been searching for.
