About Birdline tees at Birdline Outfitters

What a Birdline tee is made of

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.

Choosing a tee for the field

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.

Sizing and fit

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.

Our promise: no ruffled feathers

30-day guarantee. No ruffled feathers — every Birdline tee is backed by it.

Any two tees ship free. Free U.S. shipping on any two tees.

Field Set pricing. Put three or more tees in your cart and each drops to its Field Set price: Signature from $34, Everyday from $24.

Fewer than 1% refunds. Across all Birdline sales, fewer than 1% of customers have asked for one — the tees arrive as pictured and fit as described.

Order the right size the first time. Every product page has a Find Your Fit guide with chest and length measurements for each size, so check it before you order.
