In 2016, our journey kicked off with the first generation STP Boxer, showcasing a hanging sling pocket attached to the band. With the arrival of our 2nd generation in 2018, we introduced remarkable improvements to the slinging pocket featuring an elastic trim that stretches to different sizes, ensuring greater compatibility of your equipment and also allowing the packer/STP cup to sit either inside or outside the interior pocket, depending on your preference.
The STP Boxer has evolved again! The 3rd Gen Hybrid combines the incredible comfort and perfect fit of the beloved TRUHK boxer with the valuable insights from the 2nd generation STP Boxer.
By merging the best of both worlds - the sought-after STP Jock and the super soft TRUHK - we've created a product that offers unparalleled flexibility, freedom of movement, and rock-solid stability. In combination this 2 piece set is the ultimate fusion of style, comfort, and functionality - allowing you to mix and match larger packers and STPs with ease.
Looking to pack with an extra small packer? Then make sure to check out our Top Loading Boxers or Shift Boxer Packers, tailored specifically for that purpose. With their minimal design and deep pockets, you can trust that the packer will stay securely in place, giving you a confident and worry-free day.
MATERIALS & CARE:
- 95% bamboo, 5% spandex.
- Machine wash cold, tumble dry low.
