Hidden Flask Infinity Scarf

The FlaskScarf looks like an ordinary lightweight infinity scarf in navy and white chevron or a solid color, until you find the zipper. Tucked inside is an 8 oz bladder with a bite valve, so a sip is just a gentle bite and no unscrewing. Double loop it and the bulge mostly disappears under the fabric.

It makes the most sense for a tailgate on a cold afternoon, a long day at a game, or a gift for someone who enjoys a bit of mischief and wants something they can actually wear. Check the rules before you go, since many stadiums and festivals don’t allow outside drinks, and keep your sipping to what you’d be comfortable doing in public.

The drawback is the setup. You need to fill it and remember the collapsible rubber funnel, because pouring blind is how you end up with a wet sleeve. It’s also a light scarf, so it won’t stand in for a proper winter layer, but as a fun accessory with a secret, it does its job.
