T-Shirt Size Comparison

DACHS T-shirts use high-quality heavy cotton with a unisex slim fit. The sizes can surprise people because the profiles align with our cycling clothing, but the fabric is much less stretchy.

We usually suggest men size up, as our T-shirts are shorter than many high-street brands (especially compared to modern oversized T-Shirts.)
For women, the unisex cut is less waisted for a modern look, and many women prefer to size down for a tighter fit.

Please remember not to feel offended or weird ordering larger sizes — the sizes refer to the T-shirts and they simply step up from XS. They do not define the body size of the people who wear them!
