PlanetBox Glacier Chug Water Bottle

Recommended

The same insulated 10oz bottle as the Glacier but with a steel screw cap - you drink off a bare steel rim, so silicone never touches the water.

The verdict: Silicone only

Two materials, and the split between them is better placed than on most bottles: 304 stainless for the body and the screw cap, LFGB silicone for the cap gasket, the collar, the cap tether and the base boot. Because the cap is steel and there is no straw or spout, the mouth you drink from is the bare steel rim of the bottle - so unlike its flip-straw sibling, no silicone sits in the drinking path at all, and the only silicone touching water is the gasket. PlanetBox's own spec line for this one goes further than it does anywhere else and calls it a plastic-free product outright.

Lead safety: Tested lead-free

Double-wall vacuum bottles are sealed at the base with a solder dot, which is where lead has historically turned up in this class - Lead Safe Mama found a leaded solder dot on a PlanetBox water bottle, which the company reportedly removed after being contacted. PlanetBox's bottle FAQ states that its insulated bottles use SAC solder (tin, silver and copper), a standard lead-free alloy, and this bottle is one of them. Note the weaker chain than on the Glacier: that model carries "Lead-free solder" in its own spec line, whereas the Chug's spec line omits it, so the claim here rests on the brand-level FAQ rather than the product page. Either way it is a manufacturer statement, not a published lab result, and this bottle has not been independently XRF tested.

A 10oz insulated bottle about 7 inches tall, built for drinking rather than sipping - unscrew the steel cap and the whole mouth is open. The cap stays attached by a silicone tether, which is the detail that makes it work for school: there is no separate lid to put down and lose. Cold for up to ten hours, and rated for cold drinks only. The lid, collar and boot all come apart for washing, and the wide opening means you can actually reach inside.

Pros

  • Nothing but steel in the drinking path - no straw, spout or plastic lid
  • Tethered cap cannot be lost, and there is no mechanism to jam
  • Wide steel mouth is genuinely easy to clean and takes ice
  • Cheapest way into this line, and often discounted heavily

Cons

  • 10oz is small, and a chug opening empties faster than a straw
  • Cold drinks only; not rated for warm liquids
  • An open mouth spills more readily than a spout if knocked over while drinking
  • Few reviews so far, and the early Amazon rating is middling
