RST Tech X Coolmax Baselayer Pants - Men's Moisture-Wicking Base Layer | 100221

Engineered specifically for motorcyclists who refuse to let sweat and heat compromise their focus, the RST Tech X Coolmax Mens Pant delivers a certified-performance base layer that actively manages moisture and temperature beneath any riding gear. Built from CP-U Fabric with a Coolmax Finish, this men's motorcycle base layer pant keeps you drier and more comfortable across every mile, season, and riding style.

Key Features

• CP-U Fabric construction with high-performance moisture-wicking properties draws sweat away from the skin efficiently
• Coolmax Finish enhances climate regulation and sustained comfort on long-distance rides
• Designed as a true first layer — reduces friction and improves comfort directly against the skin
• Versatile across warm-weather touring, cooler transitional riding, and daily commuting
• Jacquard RST logos integrated discreetly into the fabric for a clean, premium look
• Lightweight and functional enough for year-round use under leathers, textile trousers, or touring suits

Performance Fabric That Works Hardest When You Do

The RST Tech X Coolmax Mens Pant is constructed from CP-U Fabric, a performance textile specifically selected for its ability to transport perspiration away from the skin rapidly. Under the sustained heat and pressure created by a leather suit or textile riding trouser, ordinary base layers quickly become saturated and uncomfortable. The CP-U Fabric prevents this by moving moisture outward, helping to maintain a more stable microclimate against your legs throughout the ride.

The Coolmax Finish built into the fabric amplifies this effect. Coolmax is a well-established performance fibre technology engineered to accelerate moisture transport and keep fabric feeling dry even during high-output riding. In practice, this means the RST Tech X pant stays comfortable during aggressive track-day laps and equally during long touring stints where heat and humidity accumulate over hours.

The Right Base Layer Beneath Every Type of Riding Gear

This base layer pant is designed to be worn directly against the skin as the foundation of a layered riding system. It works equally well beneath:

• One-piece and two-piece leather suits
• Textile riding trousers
• Touring and adventure suits
• Track and race apparel
• Everyday commuter riding gear

Riders who cover significant mileage understand that the layer closest to the body has an outsized influence on overall comfort. A quality motorcycle base layer pant eliminates the clammy, chafing discomfort that standard cotton underwear causes under technical riding kit, and the RST Tech X delivers exactly that functional improvement.

Important Safety Note

The RST Tech X Coolmax Mens Pant is classified as a functional base layer only, not as protective clothing. It carries no CE armour certification and is not intended as a standalone safety garment. It must always be worn in conjunction with certified protective motorcycle trousers or a full riding suit that meets the relevant EN/CE standards. Its role is to optimise thermal comfort and moisture management within a complete protective riding system.

Fitment & Compatibility

The RST Tech X Coolmax Baselayer Pants are designed for male riders and are available in sizes S/M, M/L, and L/XL. Intended for use beneath all categories of motorcycle riding trousers and suits. No specific vehicle fitment applies.
