Running Shirts
A running shirt has one job: disappear. No flapping fabric at pace, no wet cotton clinging to your back after 10K, no seams you notice at kilometre 30. Sunday Running shirts are made from lightweight technical fabrics that move with you and dry fast, in a clean, understated design that works on a Tuesday tempo run and on the start line.

What to look for in a running shirt
- Fabric. Technical polyester or a blend that wicks sweat and dries fast. Cotton soaks up sweat, gets heavy and chafes.
- Breathability. Perforated or mesh panels where you get hot — back, underarms — keep your core temperature down on fast runs.
- Fit. A slim fit doesn't flap at pace and doesn't rub. A race shirt should feel close to the body without restricting your arm swing.
- Sleeve length for the season. Short sleeves or a singlet for spring to autumn and race day; a long sleeve as a base layer or stand-alone top for cold mornings.
- Seams. Flat, minimal seams matter more the further you run.

Frequently asked questions
The Race Shirt is a short-sleeve, perforated, slim-fit shirt built for fast training and racing in mild to warm conditions. The Long Sleeve is a lightweight four-way-stretch top for cold mornings and cool race days. Many runners own both and switch with the season.
It's a lightweight layer, not a winter jacket: ideal on its own for cool conditions, and as a base layer under a jacket when it gets properly cold.
Slim and athletic — it sits close to the body so it stays quiet at pace. If you prefer a looser feel, order one size up. The size guide is on the product page.
Technical fabric needs to be washed after every run and dried quickly. Wash cold with a normal detergent, skip fabric softener (it blocks the wicking), and hang dry.
That's what they're made for. The Race Shirt is worn on start lines from 5K to the marathon; the Long Sleeve covers cold-weather races and early-season training.
