Go the Distance in Knobby's Long Leg Underwear

If your day involves deadlifts, long drives or thighs that have never once got along with a short inseam, the long leg trunk is the cut you have been missing. A 23cm inseam stays put instead of creeping north, flatlock seams sit flat against the skin so nothing rubs, and the ergonomic pouch keeps everything supported and cool. Knobby prints them in artwork you will actually want to be caught in, and our Undie Club drops a fresh design at your door every month so the drawer never runs dry.

Buy Men's Long Leg Underwear Online from Knobby

Every pair is designed in Australia, cut from breathable fabric and built to survive the wash cycle far longer than the servo three-pack you are currently wearing. Not sure whether you sit between sizes? The size guide on each product page walks you through it in plain measurements. Order a pair, or let the Undie Club surprise you with a new design each month and skip or cancel whenever you like. If they are not the comfiest men's underwear you own, our returns and exchanges are refreshingly painless.

FAQs

What is long leg underwear best for?

Anything where a shorter cut would ride up: training, long days on your feet, long drives, or simply having thighs that rub. The 23cm inseam sits well down the leg, so it stays where you put it instead of bunching at the top.

Will Knobby's long leg trunks ride up?

That is the whole point of the cut. The longer inseam and four-way stretch fabric hold the leg in place through squats, stairs and sprints for the bus, and the flatlock seams mean there is no thick edge to dig in when they do move.

How do I choose my size in the Long Leg?

Go by the size guide on the product page rather than the size on your jeans label. If you are between two sizes, most people prefer the larger for the long leg, since the extra length is doing the work of staying put.
