The RH+ Kinox base layer has become one of my favourite go-to products since summer has (intermittently) arrived, as it feels comfortable and shifts moisture really well.
It's mostly polypropylene (78%, if you're taking notes) with the remainder polyamide (nylon) and elastane. Sometimes polypropylene can feel scratchy but not here – this is comfy stuff.
The fabric itself is very stretchy thanks to the elastane, and the mesh construction gives even more stretch so you get a close, form fit without tightness or ridges.
After reading some good reviews for various bits of Zero rh+ kit (to give them their full title) I was pretty excited about testing these Stretch Congtrol big tights. Having spent more than a few hundred miles in them over winter, in just about all possible riding conditions I'm a bit less excited. Unfortunately as Mat found with the Power Logic Olympic bibs from Zero these just come up a little short for the clearly premium price tag.
