Thermos GTB Ultimate MKII Flask 900 ml

  1 of 8

  This is now the third we have bought as they are so good. Indestructible and excellent at keeping drinks hot for long days on the fells, kayaking, canoeing and open water swimming. The most efficient flasks available. Easy to clean thoroughly as the whole top unscrews. The only niggles are the silicon bands don't stay put, and if you damage the rubber seals, you have to replace the whole top assembly.

  Bought this primarily for work use and it does a great job at keeping my tea hot all day. The screw cap is a simple design and easy to clean which much better than other stoppers with fancy pop up caps. Overall a robust quality flask that does a good job of keeping things hot. Backed by Woodlores quality service and prompt delivery.

  This flask defies the laws of physics! I don't know how it's possible to keep drinks warm for 24 hours but this flask does it. Overall the size and shape allow it to fit in a small rucksack. The nozzle design is so easy to use I have poured coffee one handed. If you are looking for a new flask for whatever reason, this one may not be the cheapest but it is the best. I am considering buying another one of these.

  I have had some flasks over the years but nothing compared to this one, just buy it - you will not be disappointed.

  Since I got this I've been using it for going to work and also out door trips. I have to say I am super happy with this product. It is lightweight and keeps your drink at the right temperature for a really long time. I absolutely love this and I strongly recommend it.

  Excellent thermal insulation properties, clearly well made. We have three of these. Would consider something lighter, with similar robustness.

  A very well thought out flask. The 2 part stopper is far better than the push button types and they don't fill with gunk which can be hard to clean. Keeps my coffee pipping hot over 9 hrs while at work, even down to the last cup. Seems to be very robust, but only time will tell on that.

  Only received today but initial impressions of this flask are extremely good. Feels solid and strong but it's very light, basically as light as a regular water bottle. Screw top lid is simple, secure and makes a good seal. Easy to pour and take apart. Plastic mug fits securely on the top and also nests in a Zebra stainless mug perfectly. As for holding hot liquid. I put boiling water inside at 11AM today, it's now 8:30PM with the water still at scalding, tea brewing, burn yourself hot temperature. I've never had a proper Thermos before and thought it would probably do a couple of hours on a hike, but it would easily hold hot water through the day for freeze dried meals in the evening or overnight for a coffee/hot wash in the morning without getting another fire going. A Thermos is perfect for hot drinks on the hills in winter but for this weight and size, I think it'll be coming on quite a few trips in summer too.
