Our Merino Sleeveless Summer Baselayer is built on the same premium wool blend using Australian merino as our short and long-sleeve base layers, in a streamlined sleeveless cut. Natural temperature regulation and odour-resistance carry across changing intensities. The sleeveless construction strips bulk from under your jersey and opens airflow across the core, keeping you cool when the mercury climbs and dry when intensity rises. A trusted layering piece that pulls double duty — performance underwear on race day, second skin for all-day comfort.
