What could be more satisfying than sitting around the campfire after the work is done with a tumbler full of beer (other beverages are available). What you don't want is glass - it'll break or plastic - you'll have to throw it away eventually and pollute the planet. Get yourself a stainless steel cup and it'll be yours for life.
The Pathfinder Stainless Steel Pint (it's an American pint by the way, or 16 US fluid ounces - 473 ml, slightly less than the standard British pint of 20 fluid ounces or 568ml) is food-grade 304 stainless steel. It is durable, versatile, and dishwasher safe, electro-polished and laser-etched for a clean, classy look that lasts.
