The first layer. The one that matters most.

The base layer does the quiet work
A base layer manages moisture and temperature against your skin — the difference between comfort and a cold, damp ride. Isadore was founded in 2013 by twin brothers Peter and Martin Velits, former Tour de France and Vuelta professionals who know how much that first layer matters.
Merino and synthetic, for every temperature
We offer base layers in both merino wool and technical synthetics. Merino regulates temperature naturally and resists odour for cool-weather and multi-day riding; synthetic mesh is ultralight and fast-wicking for hot days.
From summer heat to deep winter
The range covers the full spectrum — sleeveless mesh for high summer through to thermal long-sleeve layers for freezing conditions, so there's a base layer for every ride.
Made in Europe, built to last
Every Isadore base layer is made in Europe under strict social and environmental standards — quality you can feel on the first ride and the hundredth.
