Does the river call you when you're at home sitting on the couch like it does me? I reach for this each time it does, it seems to bring me closer with each sip. This 30-oz travel tumbler has been laser-etched with our Blackwater Paddle Club logo. BPA-free and constructed of stainless steel, double-walled vacuum-sealed, rust-proof, and sweat-free design. This tumbler is designed to keep drinks hot or cold all day depending on your needs.
