Category: packing underwear

This version of our classic 6” fly boxer briefs features a deep pocket to securely and comfortably accommodate a soft FTM packer. Combined with our oh-so soft stretch-blend cotton, signature stay-put waistband, and chafe-free mid-length coverage, these briefs ensure comfort and confidence all day long. Because the packer sits inside a pouch, STP use is not recommended.

Oopsie: we made this batch a bit small– we recommend sizing up one from your usual size.

Customer Reviews (4.6 / 5 · 5 reviews)

Chloe ★★★★★

The stretch-blend cotton is genuinely soft against the skin, and the stay-put legs mean I don't have to adjust anything during a full workday. The pocket sits snug without shifting, which is exactly what I hoped for.

George ★★★★★

The soft stretch-blend cotton is what sold me, and it genuinely feels like a second skin all day. That deep pocket sits so flush against me I forget it’s there, even during a sweaty commute.

Timothy ★★★★★

The deep pocket keeps my packer in place all day without any shifting, and the cotton blend is soft enough that I forget I’m wearing them. Even after a long commute and a workout, they stay put and don’t ride up. Finally, underwear that actually does the job.
