Steen Luxury Bamboo Boxer Briefs with Fly and LastDrop Technology™

Most boxer briefs stop at "comfortable." These go one step further, with a discreet, built-in barrier that keeps the last drop exactly where it belongs, so you can get dressed once and forget about it. And now with a fly, so you don't have to pull the whole thing down.

The fly, without the compromise
Adding an opening to leakproof underwear is the part most brands get wrong. Ours is a horizontal fly, which opens with one hand and closes flat, and the LastDrop™ membrane runs uninterrupted behind it. You get the convenience of a fly with none of the protection traded away.

The last drop, handled
LastDrop Technology™ is a thin, breathable layer built into the front panel. It catches and locks away the moisture that ordinary underwear lets straight through. No wet spots, no second glance in the mirror, no changing trousers at two in the afternoon. You won't feel it's there. Neither will anyone else.

Bamboo viscose that feels like nothing at all
95% bamboo viscose, 5% elastane. Bamboo viscose is finer and smoother than cotton against the skin, and it moves moisture away from the body instead of holding it, which is also why these stay fresh through a long day. The elastane gives four-way stretch, so they move with you and snap back to shape wash after wash.

Details you'll notice by not noticing them

  • Wide covered waistband that won't roll or dig in

  • 6 cm inseam that stays put, with no ride-up

  • Contoured pouch for support without pressure

  • OEKO-TEX® Standard 100 certified

The details
Material: 95% bamboo viscose, 5% elastane. LastDrop™ membrane: 100% TPU
Inseam: 6 cm
Colours: Black, Blue, White
Sizes: S to XXXXL.
Care: Machine wash at 30°C. Tumble dry low. Skip the fabric softener, since it coats the fibres and reduces absorbency. Don't iron over the membrane.
