Converted for packing by Bullet Briefs. Bullet Briefs offers three styles of packing inserts.
The Free-Ball insert features a lightweight nylon/spandex top with a fabric ring to place the packer shaft through for front fly access. An elastic ball cage is attached at the bottom to hold the ball pack securely in place.
The All-In-One insert consists of a lightweight, nylon/spandex pocket which opens midway down the back and features a fabric ring in the front side. The packer inserts through the back opening. Based on personal preference, the shaft of the soft pack may be left in the pocket, or extended through the front hole for fly access. The ball pack slips into the lower portion of the pocket for security.
The third and most popular design is called the Jock Pocket. Similar to the All-In-One insert, the Jock Pocket features a fabric ring in the front side to extend the packer shaft for front fly access, if desired. This insert, however, is a top-loading pocket. There is no back side access, so this insert is not suitable for STP use. We use a variety of brands to fill this item. Hanes, Dickies, Jockey, or other cotton, cotton blend. With or without fly, depending on the band or style. There are no hard rubber c-rings in any of the three designs. Patent pending. If you are using the boxers for STP, please mention this in comments as we will choose from boxers that have a working fly.
