We compared two popular 1 litre Tritan water bottles: the wide-mouth Nalgene and the CamelBak Eddy+.

What we looked at

Material, opening and cap design, leak-proofing, markings and cleaning, and price.

The verdict

If you want a wide mouth for ice cubes or energy powders, ml and oz markings and a loop-top cap that clips to a rucksack, the Nalgene is the classic hiking bottle, at £18.37. If you would rather sip through the CamelBak Eddy+ cap, described as spill-proof when drinking and leak-proof when stowed, with a two-finger grab handle, it is £24.99.
