IXON Underground Seamless Baselayer Trousers | Men's Motorcycle Base Layer

Day in, day out under leathers or a textile suit, the right base layer makes an enormous difference — and the IXON Underground Seamless Baselayer Trousers for men are built precisely for that job. Constructed without seams in a close, athletic cut from a nylon-elastane blend, they sit invisibly beneath your riding kit, move with your body and eliminate the pressure points and friction that standard underwear creates.

Key Features

• Seamless construction eliminates chafe and pressure points in high-wear areas
• Close, athletic fit sits flat under leathers or a motorcycle suit without bunching
• Nylon and elastane blend provides genuine stretch and freedom of movement
• Lightweight and unobtrusive — adds virtually no bulk under close-fitting kit
• Suitable for road riding, trackdays and circuit use
• Designed specifically as a base layer beneath motorcycle clothing

Everyday Comfort Worth the Investment

Most riders discover the value of a proper motorcycle base layer the hard way — after a long motorway stint in standard cotton underwear that has bunched, chafed and distracted them for the final hour. The IXON Underground solves that problem without any fuss. It is an uncomplicated, well-made piece of kit that simply does its job every time you gear up.

The seamless construction is the detail that matters most here. Where conventional garments have overlocked seams running along the inner thigh and crotch, the Underground has none. The result is a surface that stays smooth and neutral against your skin for the duration of the ride, whether that is a commute, a weekend tour or a day at the circuit.

Close Fit for Sporty Riding Positions

The Underground is cut for a genuine close fit — not merely slim, but body-following. Under a tight leather suit or a form-fitting textile trouser, it adds no discernible extra layer. There are no folds to create pressure points and no excess material to gather at the knee when you adopt a committed riding position. Riders who spend time on the pegs or leaning forward on clip-ons will notice this most clearly.

The elastane content in the fabric allows the trouser to move with the leg through every angle the riding position demands — shifting weight, putting a foot down, stepping over the bike. It recovers its shape immediately and stays in position throughout.

Seamless Comfort Under Leathers and Riding Trousers

The Underground works especially well in the following situations:

• Under leather one-piece or two-piece suits
• Under race suits on trackdays
• Under close-fitting sports motorcycle trousers
• On long touring stages where comfort over many hours matters
• On circuit where concentration cannot be broken by discomfort

Any rider who has previously relied on ordinary underwear under their riding kit and found it wanting will immediately appreciate what a purpose-built seamless base layer returns in comfort over the course of a full day.

Fitment & Compatibility

The IXON Underground Seamless Baselayer Trousers are designed for use as a base layer beneath all forms of motorcycle clothing — leather suits, race suits, textile trousers and sports motorcycle trousers. They are intended for men and are available in sizes XS through 2XL to suit a full range of builds.
