I needed a reliable flask for my coffee in the mornings for my commute, and I didn't want anything with an exposed lid. This Stanley flask is perfect for what I need, and it even keeps my coffee piping hot for hours, so I can sip it at my desk before clocking in.
I picked these up for rainy hikes and they're extremely light, flexible, have excellent breathability and rain protection. The price on wildhunter was great value for money too.
