Insulated bottles test

Guy test tons of things. Test for hot and cold temperature retention and durability.

Good review, thanks for posting.

We’ve been happy with our Hydro Flask bottles. They have a few small dents but the lids are very durable and leak proof. They keep things cold on a hot day and hot on a cold day. We don’t use HDPE (high-density polyethylene) bottles much any more. About the only time is when we’re bicycle riding because the stainless bottles don’t fit well in bike frame bottle holders.
