Sheath underwear were born out of a need to put a barrier between shaft, balls and thighs, to create a space for cis men’s junk to be separate & supported.
Luckily, this design is also great for packing!
The Sheath 4.0 features a 3.5 inch inseam, an athletic-style waistband along with the dual pouch technology. The Dual Pouch includes a pocket to support the balls of your packer, a circular seamed hole for the shaft to sit through and a fly for quick access. This also comes in handy if you are using an STP.
Sheath underwear is made from a 92% Modal and 8% Elastane fabric blend. Modal is a semi synthetic material made from the beech tree. It is an antimicrobial, breathable, and very flexible material. It is very soft, drapes well, resists creasing, and has a smooth lustrous finish.

For the best fit with, it will depend on our build and if your weight fluctuates. The Sheath team recommend that If you're an athletic slim body type, with thinner thighs and smaller butt, keeping to your usual size would be better. Especially if your weight stays pretty steady. If you're on the thicker side, with larger thighs and butt, a larger size would work better. The underwear should fit like a second skin, they should fit snug but not tight.
Keep in mind that, although Sheath are great for packing, they aren't specifically designed for packing. If you are after a packing underwear which is made specifically for packing, check out the Spareparts Pete range.
