Insulated Flask - Thermo Flask Hot & Cold ONE Light - With Fruit Filter - Leakproof - BPA-Free - 18/8 Stainless Steel - 0.55L

Wanted to keep drinks cold for gym, use pre and post events and while on indoor bike. After comparing moon cup, yeti, stigg came out top, have numerous of thier bottles. Fits into bike bottle cage and has a lock on the lid to prevent accidental openning. Drinks kept cold. Passed partners access to wash My only minor point against is the drink spout cannor be rotated, its placed to avoid lid and closure fixture , 10° movement idea and woulld be ideal for hot drinks, much be prefer "traditional" openning on sports bottles for cold drinks

Nice quality unit - feels like quality as it has a heavy feel and perceived robustness. I have not tried the extended capability of keeping drinks hot for hours as yet, the keeping cold part works perfectly. The changing of the mouthpiece angle has proven to be more difficult than expected so I’ve left it as delivered which is fine. Other than that a great (if small) unit - 550ml as advertised but it just seems small…will fit in backpack side pocket perfectly.

Got 2 of these now as my kids keep stealing them. Keeps liquids cold and hot for more than needed

Much better than the non insulated version. The bottle dents easily. The lid doesn't violently 'pop' when filled with carbonated water, unlike the non insulated version. Keeps water cool for many hours.

Great flask and the only one I could find that is certified for sparkling drinks/water. No leaks, well balanced and well made. easy to open and close whilst driving. It does open with a "pop" when sparkling water is used but makes you feel like you are opening a bottle of Champagne!

Nice solid item, drinking spout works well for me

The bottle itself is nice, but the design of the lid is very poor. It is difficult to disassemble and reassemble for cleaning. The whole lid assembly is held in place by small, rigid, plastic tabs that look like they will break easily. Also, the drinking lip is too small and is awkwardly positioned, too close to the flat part of the lid. I have an older, non-insulated SIGG bottle that I have been using for at least 15 years on my travels in many countries and on hundreds of hikes etc. It is simple, well-designed and looks like it will go on for many years to come. It is one of my most reliable pieces of equipment. I hope SIGG will return to making that kind of well-designed, long-lasting product. That was the original appeal of the brand.

Brilliant ice remains frozen for 24 hrs!!! Love this flash easy to clean and drink from open spout great brand
