01

Stays Dry

Breathable, moisture-managing fabric moves sweat off your skin through a full moto, instead of soaking it up like cotton.

02

No Chafe

Ergonomic, chafe-free seams and 4-way stretch that moves with you on the pegs, in the seat and through the whoops.

03

Stays Put

A long leg that covers the inner thigh under knee braces and pants, and a waistband that doesn't roll or ride up.

Raced In MXGP Before It's Sold

Nested was started by two cousins, Camden and Bryn. Camden races MXGP for the Triumph Racing Factory Team, and every pair is worn and raced by him first. If it survives a professional race weekend - the heat, the mud, the 30-minute motos - it earns a place in the range.

This season that kit was on the top step: Camden's first MXGP overall win, and an overall victory in the sand at Arnhem. Read our story.

Why Riders Chafe - And How Good Underwear Fixes It

Motocross is hard on skin. You're standing, gripping with your knees and sitting back down hundreds of times a lap, in heavy pants and knee braces, sweating the whole time. Three things cause most of the rubbing:

What To Wear Under Your Riding Gear

Motocross Underwear FAQ

What underwear should I wear for motocross?

A snug, long-leg boxer brief in a moisture-wicking stretch fabric. The longer leg covers the inner thigh where pants, seat and knee braces rub, and a fabric that moves sweat away keeps you from chafing over a full moto. Avoid cotton: it holds sweat and gets heavy. Read the full guide.

Do Nested boxer briefs work under knee braces?

Yes. The long leg sits between your skin and the brace straps, so the straps rub the fabric rather than your leg. Pair them with knee-brace socks for full coverage.

How do they stop chafing?

Breathable, moisture-managing fabric with 4-way stretch and ergonomic, chafe-free seams. The pair stays in place instead of bunching, which is what causes most rubbing on the bike. More on chafing.

What size should I get?

Go by your waist first: XS fits about 60 cm, S 64 cm, M 68 cm, L 72 cm and XL 76 cm. As a rough guide by height and weight: XS 155-165 cm / 45-52 kg, S 165-170 cm / 52-60 kg, M 170-175 cm / 60-67 kg, L 175-180 cm / 67-75 kg, XL 180-185 cm / 75-87 kg. Between sizes? Take the smaller one for a race-day compression feel, the larger for everyday comfort. Every product page has a size finder.

Are they only for motocross?

No. They are raced at MXGP level, but most riders wear them every day too: training, the gym, enduro, mountain biking and work.
