This is the “shoulder-strap Tritan bottle” used by Backpacking Light founder Ryan Jordan. Ryan spec’d this bottle with a thinner-walled Tritan plastic than what you’ll find in Nalgenes and other (heavier) water bottles. At 35mm, the opening is still small enough for easy glugging, but much easier to fill in lakes and stillwaters than narrow-mouthed 28mm bottles.

The 3.2-ounce weight can be lightened up a little (0.3 ounces) by removing the metal cap shell.

The 20-ounce capacity is perfect for shoulder strap or hip belt use or easy retrieval from backpack side pockets.

Tritan plastic is heat-tolerant, making it a great option for hiking with hot coffee or soup without leaching bad plastics into your food. In addition, Tritan is a highly inert material, which makes it great for storing flavored drinks, soups, coffee, tea, or alcoholic beverages without taking on the taste and smell of the contents.
