Excellent product, but a bit smelly
Got this free with my 800ml Ecotanka. After removing it from its plastic wrapping, I was it by a strong chemical smell. I've bought neoprene products before, but they've never had such a strong smell. The strap that comes with it was also quite stinky. After soaking everything in Ecostore laundry powder for about a week, and leaving it in the sun for about a week (while intermittently rinsing in soapy water again, the smell abated enough to use it. There's still a hint of eau de toxique about it, but it's tolerable. All a bit ironic from a company that has 'Eco' in its name.
Anyway, totally worth getting though. Have dropped my bottle a couple of times now and the extra padding has reduced the likelihood of dings. The strap isn't my thing, but I've slapped a couple of carabiners on the strap rings and the stitching is sturdy enough to support the weight of a full bottle on just one ring while you're walking around.
