OXO Strive Advance Bottle
It’s got a narrow opening at the top to sip water. But the OXO Strive Advance Bottle also unscrews a bit further down at full width, making cleaning and filling with ice far more convenient — a clever design that’s logical but still surprisingly absent on almost all hard plastic bottles. Made of BPA-free Tritan, it’ll holds up to 24 ounces of fluids, marked at 4 ounce increments (and also in metric on the other side) so you know how much you’ve drank. It’s also dishwasher safe and boasts a stainless steel tether between the lid and the bottle to keep from ever losing the former.
