Mavic's open mesh polyester baselayer for hot weather is so light you hardly feel it’s there. It’s stretchy enough to give a close ﬁt and all the seams are ﬂat-stitched so they feel comfortable next to your skin.
Although the back is extended, one tester could have done with a bit more length to keep well covered. Worn under a short sleeved jersey, it wicks sweat really effectively without getting heavy, while all those holes let plenty of air ﬂow through to keep you cool and comfy. A great fabric.
It’s also available in sleeveless (£23) and long sleeve (£35) versions.
