Originally I bought a different cool underlayer, but I sent it straight back as I wasn't happy with the quality. The RST tech-x is perfect! I've been wearing it underneath heavy PPE clothing for work and it has done it's job. Very comfortable to wear, also have the rst matching bottoms. Yet to ride in hot weather, but equipped with a mesh jacket I'm sure I won't be getting cooked. 5* service from SBS as always.

Great for a hot day

Close fitting but not tight. Sizing is true to normal clothing size. Really makes a difference on warm/hot days and stops that 'sticky' feeling when taking your gear off. Product is well made.

Product Specification


It's no wonder that the RST motorcycle clothing range is now one of the most popular ranges of bike kit in the UK. Their continued investment in racing, with a particular focus on BSB, has meant a constant development of product, which has translated directly to their road range. With the help of some of the biggest names in the BSB paddock, such as Tommy Hill, John Kirkham and Stuart Easton, RST have pushed the boundaries of what can be delivered through a brand that remains amazingly good value for money.
It also helps that the Derbyshire based design team are passionate about what they do; rigorously testing all RST clothing themselves. The team insist on riding all year round, despite the British weather, in order to put the RST textile range through its paces, and the fact that the team are keen track day enthusiasts, provides helpful real world testing of the RST leather range too. Their continued passion for design and innovation is highly apparent in this year's range and when you add to the mix the constant stream of positive feedback from our customers, it's easy to see why we have always covered the entire range of RST motorcycle clothing, and will continue to do so.
