Our long sleeve t-shirts are built for everyday adventure and year-round wear. Made from premium heavyweight organic cotton, they offer comfort, durability, and just the right amount of warmth—perfect on their own or layered over your favourite tee. Whether you’re heading out into the hills, keeping it casual at the pub, or looking for something smart that still feels relaxed, these long sleeve tees are the kind of wardrobe staple you’ll keep coming back to.
Every shirt is ethically made from GOTS-certified organic cotton and screen printed by us in our Dartmoor National Park workshop. The result is a clean, structured long sleeve that holds its shape, wears beautifully, and reflects the care that goes into every piece we make. As a certified B Corp and 1% for the Planet member, we're all about thoughtful design with purpose. These long sleeve t-shirts carry the outdoor spirit that inspires our brand—versatile enough for travel, camping, work, or just staying warm..
