HydroJug Traveler vs Stanley Quencher (40 oz)

What does each brand say about leaks?

HydroJug's FAQ: "Yes, completely – when the straw is in the down position. It's not splash-resistant or spill-resistant. It's leakproof." (HydroJug). Stanley describes its lid as including "a full-cover top to resist splashes" (Stanley). Stanley's Amazon listing calls the full-cover position "added leak resistance" (Amazon listing). Reviewers report that it can leak when tipped: OutdoorGearLab wrote that it "is not leakproof, even when fully closed" (OutdoorGearLab), and Good Housekeeping wrote that it "still leaks when knocked on its side and should be held upright" (Good Housekeeping). We didn't find an independent leak test of the Traveler, so its leakproof claim is HydroJug's own.

Do both fit in a car cup holder?

Both makers say so. HydroJug says all Traveler sizes "are designed to fit standard car cup holders" (HydroJug) and lists a 3.04 in base for the 40 oz (HydroJug). Stanley lists a 3.1 in base and says sizes up to 40 oz "will comfortably fit most car and truck cupholders" (Stanley). See which 40 oz tumblers fit a car cup holder.

How do their temperature ratings compare?

HydroJug's 40 oz product page says "Keeps cold up to 24hrs / hot up to 6hrs" (HydroJug). Stanley's 40 oz product page shows "11 Hrs" and "2 Days" (Stanley). Stanley's page for a limited-edition version of the same 40 oz Quencher H2.0 FlowState labels these as "11 HRS COLD" and "2 DAYS ICED," and adds "7 HRS HOT" (Stanley). Neither brand explains its test conditions on these pages, so treat these as each maker's own ratings.

On insulation, Stanley lists "Double-wall vacuum insulation" (Stanley). HydroJug's 40 oz product page lists "Double-wall vacuum" in its specifications, while the same page's description and HydroJug's Traveler collection page say "triple-wall" (HydroJug product page, HydroJug collection page).

How do you clean each one?

HydroJug says most Travelers are dishwasher safe, "top rack recommended," and that "Some prints and designs are hand wash only" (HydroJug). Stanley lists the Quencher as "Dishwasher safe" (Stanley). Good Housekeeping advises taking the Stanley lid's pieces apart to clean them, because mold can develop on the silicone if it isn't cleaned and dried properly (Good Housekeeping).

How do their sizes and lids differ?

Stanley lists the Quencher 40 oz at 3.54 × 5.43 × 11.02 in and 1.18 lb (Stanley). HydroJug lists the Traveler 40 oz at 3.9 × 6 × 9.84 in and 20 oz (1.25 lb) (HydroJug). By those figures, the Traveler is 1.18 in shorter. The Traveler has a circular flip straw with a flip tab that covers it (HydroJug). The Quencher has a rotating three-position lid with a straw opening (Stanley).
