At PATER et FILIUS, we reinvented the good old boxers to offer men a perfectly fitting and visually appealing piece of underwear. The collections, all engineered designs, either printed or plain cotton poplin, feature leisure trousers and two types of boxers. They add a dash of colour to your intimate outfit. They are bright, bold and unique. They are not for the conventional.

Poplin Boxers.

Regular (but by no means standard.)

Our regular boxer shorts are the perfect fusion of briefs and boxers, offering you the best of both worlds. They are loose and comfy like boxers with a more flavorful cut to accentuate the profile and backside while bringing you the snug, supportive fit of briefs. No crumpling whatsoever, no annoying creases – they are perfect under a suit even if your meeting seems to last a lifetime.

Short (and sweet.)

If you are more of a denim aficionado, our short boxers will ensure a sharp silhouette in those jeans while keeping everything in one place. In fact, the short boxers offer the same features as the regular ones, but sit lower on the hips giving you just enough fabric to cover all the essentials (but not much more). Their shorter leg makes them comfortable to wear under just about anything.

Poplin Leisure trousers.

The fastest way to make yourself relax.

You’ll love these thin-legged, super comfortable trousers – for leisurely lounging about as well as sleeping in. Wear them any way you want (yes, naked too!) – they bring you the same signature-cut comfort and smooth lining as our boxers.
