Ettinger has designed a compact hunter’s flask of stainless steel, covered in waxy chestnut hide leather to protect your fingers from the cold metal. It comes with 4 small cups that fastens under a leather strap. Each cup can hold about 30ml (1oz). With each flask comes a stainless steel funnel for easy filling. It is a must for that fishing trip or mountain hike where a little something can be needed to stay warm.
