The quality of the bottle is fantastic, the laser etching is very nice, the ability to keep liquids cool is great (we’ve just been through 30 degree heat in UK). The downside is that even though I’m not a weight weanie but when filled it’s a brick and then you realise it holds very little for the same size bottle. The other point to make it my mistake but due to the nozzle/straw design being different due to not being able to squeeze the water out, if you put it in bag make sure to lock the cap off else you’ll end up with the entire contents inside your bag and nothing in your bottle.
