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.
