Contigo AUTOSEAL West Loop

The Contigo West Loop is ideal for the user who prioritizes superior temperature retention and wants easier lid maintenance. If you need your coffee hot for 13 hours or water cold for 28 hours, this mug excels. Its top-rack dishwasher-safe lid is a bonus for busy individuals, even if the body needs hand washing. This is also a more budget-friendly option for those seeking high performance without the premium price, provided car cupholder fit isn't an absolute guarantee.

Contigo Byron Vacuum-Insulated Stainless

The Contigo Byron suits the daily commuter or traveler for whom guaranteed car cup holder compatibility is a non-negotiable feature. With a 2.8-inch base diameter, it ensures a snug fit on the go. While its insulation (7h hot, 18h cold) is respectable, it's chosen more for its road-trip readiness and durable stainless steel build. If you prioritize ease of transport in your vehicle and are willing to hand wash the entire mug, the Byron justifies its slightly higher price for this specific convenience.
