Most Birdline tees are printed on heavyweight garment-dyed cotton in a relaxed unisex fit. The fabric, fit and care for each design are listed on its product page.

Birds notice movement and contrast long before they notice you. Muted earth tones — olive, sand, stone, bark — blend into cover; skip white, which reads as a flash of movement from across a field. Matte garment-dyed cotton doesn't catch the light the way technical fabrics can. Start the morning in a heavyweight tee and carry a light mid-layer for when the sun clears the treeline.

Birdline tees are a relaxed unisex fit with room to move. Every product page has a Find Your Fit guide with chest and length measurements for each size, so you can check before you order.
