The Outdoor Bottle has the capacity of 1000 ml/550 ml of liquids. It is made of BPA-free Tritan™ that does not interfere with water and does not change its flavor. Apart from that it's a highly durable material that withstands low and high temperatures from -10 up to 90°C. Wide mouth prevents the liquid from freezing easily, makes it possible to draw water from any source and fix meals by stirring. The bottle has an integrated seal mounted in the cap. The Outdoor Bottle is compatible with other Helikon-Tex products: the Camp Cup and the Essential Kitbag®.
