RST Tech X Coolmax Men's Long Sleeve Base Layer Top | 100219

Hours in the saddle demand a base layer that works as hard as you do. The RST Tech X Coolmax Men's Long Sleeve Top is engineered for all-day comfort across changing conditions — keeping you dry, comfortable and focused whether you're threading through a summer commute or deep into a long-distance tour.

Key Features

• CP-U fabric construction with strong moisture-wicking performance to draw sweat away from the skin
• Coolmax finish enhances comfort by reducing clamminess and maintaining a drier feel against the body
• Long-sleeve fit designed to sit cleanly as a first layer beneath a leather suit, textile jacket or touring gear
• Supports balanced body climate in both warm and cooler riding conditions
• Jacquard RST logos provide a refined finish without adding bulk
• Lightweight and low-profile — adds comfort without restricting movement or adding unnecessary layering

All-Day Comfort Built Around the Rider

Comfort on a long ride starts at the skin, and that is exactly where the RST Tech X Coolmax Long Sleeve Top earns its place. The CP-U fabric is selected for its ability to manage perspiration actively, moving moisture away from the body so it can dissipate rather than sitting against the skin. On a warm summer morning or a humid afternoon run, that difference is immediately noticeable — less discomfort, less distraction, more focus on the road.

The Coolmax finish reinforces this by enhancing the fabric's natural wicking and comfort properties. The result is a base layer that feels genuinely pleasant against the skin across extended wear, not just for the first twenty minutes of a ride.

The Ideal First Layer Under Your Riding Kit

A well-chosen base layer transforms the way your outer riding gear feels. Worn beneath a leather suit, textile jacket or any form of touring or commuting outerwear, the RST Tech X Top helps regulate body temperature and reduces the friction and cling that can build up over long miles. In cooler conditions, it provides a comfortable thermal buffer; in warmer weather, the moisture management keeps the microclimate between your skin and your jacket far more tolerable.

This makes the Tech X Coolmax Long Sleeve Top a genuinely versatile piece — useful across seasons and suited to a wide range of riding styles:

• Touring riders on extended multi-day trips
• Daily commuters in variable weather
• Sport riders seeking a clean, close-fitting base layer under a race suit
• Anyone riding through mixed warm and cool conditions

Construction and Finish

RST have kept the design purposeful. The jacquard logos are worked into the fabric rather than printed on, preserving the smooth profile that a base layer needs to sit cleanly beneath close-fitting riding gear. There are no bulky seams or decorative elements that would create pressure points over long hours in the saddle. The result is a functional garment that disappears beneath your kit and simply does its job.

Note: the RST Tech X Coolmax Long Sleeve Top is a performance base layer and is not classified as protective clothing. It is intended to be worn as an underlayer beneath certified motorcycle protective outerwear.

Who It Is For

• Riders looking for a breathable, moisture-wicking long sleeve base layer for motorcycling
• Those who run warm and want to stay drier beneath their jacket on summer rides
• Riders who need a comfortable functional underlayer for cooler mornings
• Anyone wanting to make their existing riding kit more comfortable across longer distances
