Durable, and no weird taste
I have a couple of these for carrying water around on hikes and road trips. Water tastes good, and I put juices and drink mixes in them, and there is no after taste. I've never noticed any metallic taste in the Siggs but have noticed it in the Klean Kanteen bottle I also own. KK's screw top squeaks bad when you twist it. Not so on the Siggs. I love the solid feel, and the aesthetic factor of the Siggs. I have dropped mine a few times on the concrete with a little water in it, and got nothing other than a few dings.
