Why Code of Silence

Engineered for the Hunter Who Refuses to Compromise

Ev Tarrell spent 30 years building hunting apparel at Cabela’s. When he left, he had one goal: design gear specifically for the serious treestand bowhunter who can’t afford to make noise. Every fabric choice, every seam, every zipper pull is engineered around one question — is it silent enough?

    COS does it again!

    I hunted with the fairwinds line last deer season and absolutely fell in love with the COS line. Really wanted to get my hands on the ultivent Bamboo shirt for early season and it did not disappoint. I live in Texas and we are in the high 90s during the day. Wore the shirt first time Aug 13 for a treestand, Bow Hog hunt and the shirt worked and felt wonderful in the morning with Temps in the mid 80s. I highly recommend and look forward to supporting COS for the long run! Ya did it again COS! Great job! Ps i normally wear a Large but went with a medium and plan on hand washing and air drying to reduce shrinkage. As of now the medium is perfect fit but if you plan on machine washing and drying i would recommend your regular size and follow the instructions.
