Mavic Echelon Base Layer review

This Mavic base layer seeks to provide top quality thermal insulation under jerseys and jackets, to keep you comfortable whilst riding on colder days.

Cycling Weekly Verdict

This is a good base layer. It is light weight, comfortable and performs well in a wide range of temperatures. Whilst the wicking characteristics of the polyester fabric may be superior to merino wool, some cyclists (our tester included) may prefer a natural textile against their skin.

    Polyester doesn't feel as nice as merino wool

A quality base layer can significantly enhance cold weather riding comfort. In order to do this it needs to tread the fine line between keeping you warm, whilst preventing you from overheating and wicking sweat from the skin.

At 6'1 and 70kgs we found that the medium Mavic Echelon base layer came up quite large so you may need to go down a size to achieve a close fit. The warmth of this base layer was enhanced by Mavic's 'Air Dry' fabric which did a great  job of wicking sweat away from the skin.

We never felt cold whilst wearing this and it worked well in a range of temperatures. We have had some mild days this December, that resulted in us being slightly overdressed on some occasions. Above 10 degrees this base layer can get rather sweaty, but it remains comfortable and we didn't feel too hot.

We like the logo details, that are consistent with other Mavic kit and the rear of the base layer is cut lower to ensure your lower back remains insulated, but at £45 this base layer is not cheap. Although this base layer is comfortable, we still prefer the feeling of merino wool against our skin over the synthetic polyester used in this garment.
