In detail: Contigo Free Flow Autoseal Insulated Bottle 720ml
Contigo built its name on Autoseal technology, a push-button that lets you drink and reseal the bottle with one hand without ever risking a leak. The Free Flow Autoseal 720ml applies this principle to a vacuum-insulated 18/8 stainless steel double-wall bottle, suited to the office as much as travel or sport.
Thermal performance follows suit, with claimed cold retention of up to 29 hours and hot retention of up to 10 hours, plenty for a full day without a refill. Being 100% leak-proof once the button is released is reassuring for carrying in a bag, even lying on its side, a point that often trips up more basic push-button bottles.
A safety lock prevents the button from being accidentally pressed in a pocket or bag, while a protective spout cap keeps the mouthpiece clean between uses. A built-in handle makes carrying easier, a detail appreciated for daily on-the-go use.
The Contigo Free Flow Autoseal 720ml suits anyone who prioritises everyday opening convenience without sacrificing the thermal performance expected from an insulated bottle.

Our tester's verdict: Guillaume Hoarau
Used daily at the office and then tested over several runs, the Free Flow Autoseal first wins over with its one-handed opening: a genuine comfort when the other hand is holding a phone, handlebars or a dog leash. The push-button takes a little getting used to at first but quickly becomes second nature. The 100% leak-proof claim held up without issue inside a backpack, even lying on its side. The claimed 29-hour cold retention proved solid over a full day, water staying cool even left in a car through the afternoon. The 720ml size, neither bulky nor too small, suits varied daily use. The only downside is the built-in handle, handy for carrying but adding a touch of bulk compared with a sleeker bottle. A solid choice for anyone who prioritises everyday practicality.
