I already had a 24oz thermoflask bottle and decided to upgrade to a bigger one. I got the 40oz one and honestly it's amazing. It's the perfect size to make sure you drink enough water, keeps my water cold for many hours too. It's definitely more sturdy than the 24oz one. Overall great product, big fan of thermoflask, 100% recommend.
It works great. I went with the 40z to avoid having to refill often. 4 large ice cubes keeps the water cold for about 6-8 hours. Ice cubes left in it empty overnight are still frozen by morning. It's not the most extreme insulation on the market but it's a good compromise with being thinner/lighter which makes it perfect for daily use, filled once or twice throughout the day.
A real upside to this design is the 2 tops it comes with. Both are high quality and clever design, unlike many cheaper canteens for sale. The straw spout is fully capped with a softer material that's nice to drink from. But most useful is the handle design. You can comfortably drink and carry from the narrower cap, even when it's completely full, without having to ever touch the wider body. So you've got great control over the bottle no matter what you're doing. It also gives you leverage to open and tighten and the cap so there's never any leaks. This is perfect for people with smaller hands, though the keyhole shaped handle will fit any size hands. It's VERY clever and much more functional than the pivoting strap design on most other canteens.
The caps were the big reason I chose this over others and it really does make a difference when I use it every day. It's the main reason I want to leave a review, since some designer made a pretty noticeable improvement with that clever trick.
For someone else that complained about the noise, the straw has a pretty high flow rate which is usually nice. To avoid any noise you just have to drink more slowly, like you're sipping through a regular straw. But the second included cap is general purpose, and has a latch mark on the swing-back cap so it won't flop forward while you're drinking or pouring.
Me gustó demasiado el color, también que trajera las dos tapas es una súper buena opción, esta algo pesado y ahorita por la cuarentena no lo he sacado ni nada, pero en mi casa me ha servido demasiado, tomo mucha agua y es lo que quería, se me hace súper práctico, bonito y cómodo. De igual forma, el agua si se mantiene fría como por 8 h que es lo que he probado, adjunto una foto comparándola con una calculadora científica para ver el tamaño jajaja, el mío era el de 700 mL
Nice looking bottle, its sleek and the 24oz is the perfect size for me. I was really disappointed with the fact that this doesn't keep my water cold for too long as i've heard it does for other people. The ice melts quickly and turns to room temperature within a few hours (2-3).
The lid that you unscrew to drink from also smells really bad no matter how many times i wash it and it really bothers me. The lid with the straw also doesn't work well, every time i take a sip i get air bubbles and not enough water comes through, which also makes a really loud noise. Although its a nice looking bottle, i don't recommend it.
