I’ve been fan of SIGG bottles since I was a teenager (which was a very long time ago): they’re sturdy; last a lifetime and they look pretty cool too! I’m an outdoorsy, ‘busy’ type of person and my SIGG products have travelled the world with me, turning heads wherever I go. The latest addition to the family is the Thermo, an insulated bottle that keeps drinks hot or cold (depending on what you put in them). This is due to the high-grade 18/8 stainless steel and the vacuum-insulation used to make the Thermo.
I was sent the SIGG Thermo 0.5L mug to review and I wasn’t too sure what to expect. I’ve always used a traditional flask when out for a day and a screw top thermal mug to take a brew away with me in the car. At 0.5L the Thermo certainly has the capacity of a decent sized hill walking flask but I wasn’t sure if it would keep my coffee as hot for as long. The Thermo definitely looks the part: it’s slim, cool to the touch and has a lid which is really easy to hold. I took my Thermo everywhere, and I mean everywhere…
I’m in the Royal Fleet Auxiliary (RFA) and have just been through all my Basic Training for Seafarers courses. I took my Thermo to lectures, to the lake whilst doing lifeboat training and I also tested the cold properties of the Thermo when doing my firefighting.
I played around with the thermal properties of the Thermo, following the instructions to the letter (preheat the Thermo with boiling water prior to filling with drink) and also throwing caution to the wind and NOT preheating it. When I did it properly, I made a brew at 0845 and got bored of waiting for it to get cold at 2215. In all fairness I did leave the lid on tight , only opening it occasionally over that time and whilst the coffee wasn’t steaming hot at 2215, it was still a very drinkable brew. When I made my brew maverick style, again at 0845, my coffee was still drinkable at 1500. That’s a better performance than my traditional flask and way better than any thermal screw top mug I’ve ever owned – they usually keep a drink warm for about 2 hours. As for the keeping water cold, it also performed very well indeed – definitely welcome after coming out of a burning container wearing full fire fighting kit!
The Thermo mug has a removable tea strainer, which does what it says on the tin. I made some green tea and it worked pretty well, I didn’t test it with loose leaf tea so I can’t comment on whether the strainer is fine enough for that but it definitely works well for using tea bags. No messy fishing it out of the mug!
I work hard and like to play equally as hard and I took my SIGG Thermo to Northern Ireland with me to provide a hot, home made brew wherever I went on my road trip. It really was the perfect companion on my trip, slim, unassuming and keeping my drink hot for hours. It was something special to have a coffee on the Giant’s Causeway! My friends who’ve been with me whilst testing the SIGG Thermo have tried to whisk it away on several occasions – it’s definitely a bottle that’ll turn heads!
I’m not sure that I would take the Thermo 0.5L away as a flask on the hills as I like to pour out my coffee and drink it from a mug BUT the larger sized Thermo bottles actually have a mug. Given the performance of the 0.5L I am sure the larger SIGG Thermo’s would be excellent pieces of kit for a day on the hills. I am more than happy to say that the SIGG Thermo 0.5L is the perfect companion for work and play, and I highly recommend it.
The SIGG Thermo is available in 0.3L, 05.L, 0.75L and 1L bottles.
