If you are looking for a go-anywhere food and beverage container, then check out the range of products from Hydro Flask.

I have just got hold of the 21oz Standard Mouth version complete with insulated Sport Cap, and have been well impressed.Hydro FlaskI guess you could call this the middle-of-the-road size drinks companion, and is perfect for slipping into a day pack when you are heading for the hill, or planning a road trip. The slip-free grip makes it easy to manage, and the unique powder coat is scratch-resistant. What particularly impresses me, though, is the double wall insulation, which keeps beverages cold for a day – yes, that’s 24 hours – and piping hot for up to six hours, and warm for a further six hours.

The flask is made of Pro-Grade Stainless Steel, and, in hand, feels nicely weighted and clearly durable. So whether you anticipate wanting a refreshing cold drink after a breathless climb, or a steaming cup of tea after a powdery descent, the Hydro Flask will serve you well. It comes in a nice range of colours, too. £30, www.hydroflask.com
