We’ve partnered with Cyclelogical to create some absolutely hilarious and awesome t-shirt designs. This is the “Hippo Birdy” shirt. Hippo Birdy, like Happy Birthday. Get it? Anyway, we think it’s awesome and makes a great birthday gift! And a portion of the proceeds of sales of these shirts goes to supporting our adventures, so you can get a cool t-shirt AND support us — win, win!
