Three pairs of our 9" packing boxers: one Black, one Pacific Teal, one Slate Blue. The 9" is the inseam, meaning the legs reach about 9 inches down your thigh, so they stay put and don't ride up.

SHIFT packing boxers are made for FTM, trans masc, and anyone who packs. Packing means wearing a packer, a soft prosthetic that creates a natural-looking bulge in the front of your underwear.

Inside the front panel is a built-in pocket that holds your packer in place, so it doesn't slide around while you walk, work, or lounge. You reach the pocket from the side. Not packing today? It doubles as an extra soft, moisture-absorbing layer.

Why a 3 pack? Three pairs bought one at a time cost $59.97. Here they're $49.99, so you save about $10 and restock the drawer in one go.

Materials & care: 95% cotton, 5% spandex (the stretchy bit) with a satin-soft waistband. Machine wash cold, tumble dry low.
