Men's Protection Boxers - Day & Night

Made for drips and light leaks. Holds up to 150ml (5 fl oz). Soaks up fast and locks it in. Most guys handling leaks after prostate surgery, or with age, are well covered.

Look at the size chart and take your usual underwear size. Between sizes? Drop one down.

Wrong fit? We'll exchange them, even once you've tried them on.

Menvault relies on a 9-layer system, with each layer handling one job and handling it well.

The instant a leak occurs, the first layers soak it up and dry quickly, so nothing sits against your skin. No dampness. No irritation.

From there, the liquid is drawn deeper into the fabric and held inside for up to 12 hours. Bamboo fibers naturally tame odor. No added chemicals, no smell, no need to change straight away.

The final layers form a full barrier. Very little passes through and almost nothing reaches your clothes.

You stay dry, fresh and fully in control. Throughout the whole day, every day.

The first boxer brief designed from scratch for men with real leaks. A genuine boxer brief with 9 layers worked straight into the fabric. Front, back and inner thighs. Exactly where men leak. All 9 layers pressed into a thin build. Nobody can tell.

The 9 layers sit in three groups. Each group does one job. Together they make a complete system.

Step 1 — The Catcher (Layers 1, 2, 3)
The moment a leak starts, these layers take it up fast. Skin stays dry. No dampness. No irritation.

Step 2 — The Vault (Layers 4, 5, 6)
Locks the liquid deep inside and keeps it there for up to 12 hours. The bamboo layers naturally work against the bacteria behind odor. No smell. No changing through the day.

Step 3 — The Wall (Layers 7, 8, 9)
Nothing gets through. Your clothes stay clear.

Bonded straight into the fabric. They don't shift. They don't fall apart in the wash. Toss them in with any other pair. Put them on in the morning and forget they're there.

No. Thin, close-fitting and discreet. No bulk. No crinkle. No diaper outline. From the outside they read as ordinary underwear. Nobody notices.

Yes. Machine wash at 30°C (inside out), mild detergent, air dry, no fabric softener, no ironing. That's all. Cared for that way, each pair lasts up to 3 years.
