Worked great
Worked just as expected. Kept hot stuff pretty hot for a few hours. The one tricky issue is that the outside is slippery and hard to grip. I spilled a bit my first attempt to pour hot water into a cup. I set the velcro attachment strap just loose enough to slip my hand through to secure the bottle to my hand for pouring.

Well Made
I was excited to have received my Hyperlite insulated water bottle pouch. I have not had a chance to use it yet as our temperatures have not been cold enough to need it. It looks great, is well padded and fits my Nalgene bottle perfectly. I am looking forward to testing it out soon.
