As a family we have been using SIGG bottles for three years now and they are a constant when we leave the house. We always have our water bottles with us, even if we're only popping to the shops, and I can't even begin to imagine how much money we've saved on not buying a bottle of water whilst out, let alone the environmental impact not buying plastic bottles has made. We have honestly not bought any plastic bottles of water in three years!
The SIGG Thermo is the newest addition to the range and something that I've been waiting for for a long time. It is their insulated drinks bottle, and is one of the best flasks we've tried. The bottles are made from high-quality 18/8 stainless steel and due to the double walled vacuum insulation, drinks are kept hot, or cold, for many hours.
And so to test this claim that the SIGG Thermo maintains its temperature for hours, we recently tested the 0.75l insulated flask we'd been sent to review whilst on holiday in Cornwall.
On the Sunday we decided a trip to Polzeath beach was in order, and my sister-in-law brought a Kelly Kettle with us so that we could make some hot chocolate. I filled the Thermo up halfway with cold milk (as I know The Boy can't handle hot drinks very well) and we sent off to make a fire on the beach.
The Boy helped make the fire and then we boiled up some hot water to make the hot chocolate. The milk that came from the Thermo was indeed still icy cold and it make it a lot easier for him to drink his warming drink on the beach.
This might not seem a very thorough test of the insulating capabilities but what I will say is that it is a very practical flask to use. The drinking cup can be stored on either the top or the bottom of the flask, but we kept it on the bottom mainly because it meant that we could clip the SIGG Thermo to our rucksack using a carabiner; it makes it a lot easier to carry around. My sister-in-law actually works in the outdoors and pointed out that the added bonus of it not fitting over the top of the flask is that when it's removed for a top-up, there isn't a steady stream of dregs trickling down the flask from the upside down cup! A definite bonus on a beautiful white flask!
To truly test out the Thermo we filled it full of hot coffee the next day when we visited The Eden Project. My husband made the coffee at 11am and we set off for the day. The SIGG Thermo holds three and a half mugs full of coffee which I knew would keep him going during the long day ahead and sure enough he sat down to have his first cup of hot coffee around 1.30pm. He then had another cup at four o'clock when we were recovering from the 33°C temperatures of the Rainforest Biome.
And finally when we returned home in the evening, and were unpacking our bag from the day at eight o'clock, he poured the last mug out. I'm not sure if you can see this image properly but the coffee is still steaming and was still almost too hot to drink; a full nine hours after it had been made!
I've never known an insulated drinks flask to work as well as this did, to still be producing a piping hot drink nine hours after it was first made is a pretty amazing feat. The fact that the SIGG Thermo is once again a beautifully designed bottle, free from harmful substances such as BPA or phthalates, practical in design and elegant to look at, comes as no surprise to me.
The SIGG Thermo is available in 0.3l, 05.l, 0.75l and 1l bottles, with prices starting from £19.99 for the smallest.
I was sent this product for the purpose of this review, my opinions are honest and unbiased.
