What exactly does HydroJug claim?
That quote is from HydroJug's Traveler FAQ (HydroJug). The 40 oz product page lists a "Leak-proof lid" and says the Traveler is "completely leakproof with the straw down" (HydroJug). The Amazon listing uses both "leak proof" and "leak resistant" (Amazon listing).
Has anyone independently tested it?
We didn't find a published independent leak test of the Traveler while researching this guide, so the claim above is HydroJug's own. We'll update this page if one is published.
