Water Bottles & Flasks

Water bottles and insulated water bottles for the trail, the gym and the daily commute. Leak-proof stainless steel designs led by the ION8 range, plus military-pattern bottles from Kombat.

The main choice is single-wall or insulated. Single-wall stainless steel bottles like the ION8 leak-proof range are lighter and cheaper, and they hold cold water well for everyday carry and hikes. Insulated thermal bottles have a double wall that keeps a drink cold or hot for hours, which earns its extra weight on a long day out or a winter commute. Sizes run from a 320ml pocket bottle up to a full 1L, so pick by how long you are out and how much you drink.

Every ION8 bottle here is leak-proof, so it goes in a rucksack next to a laptop without soaking it. The Kombat US-Army and 58 Pattern bottles are the traditional military option, supplied with a mug and pouch that clip onto webbing, popular for cadets, airsoft and green kit setups.

Consider the cap too. A slim body fits a cup holder and a side pocket, a wider mouth is easier to fill with ice and clean. Add a camping stove for hot drinks at camp, or browse Mess Tins, Plates & Utensils to round out your mess kit.

Frequently Asked Questions

What is the difference between insulated and single-wall water bottles?

Single-wall stainless steel bottles are lighter and hold cold drinks well for everyday use. Insulated bottles have a double wall that keeps a drink cold or hot for hours, which suits long days out and cold mornings. Pick single-wall for weight, insulated for temperature.

Are these water bottles leak-proof?

Every ION8 bottle in this range is leak-proof, so it sits safely in a bag next to a laptop or paperwork. Always check the lid is done up fully before packing.

Can I put hot drinks in an insulated water bottle?

Insulated thermal bottles are designed to hold hot drinks as well as cold. Single-wall bottles are best kept for cold water, since the outside gets hot to hold. Check each product page for its intended use.
