This Halulite is the larger capacity version which holds 568ml and it nests with a 1L Microlite bottle and can take a 110g fuel canister for easy packing and storage.
GSI Outdoors says:
The lightweight, rugged hard anodized aluminum cup/pot is designed to fit over a standard 1 Liter water bottle with folding bail handles for compact storage. Holds 20 fl oz of liquid and weighs only 2.6 oz.
GSI Outdoors' Halulite 20 fl oz Aluminium Bottle Cup weighs in at just 78g with folding handles, internal graduations and a good capacity. This cup is large enough (568ml or 20 fl. oz.) to enjoy a big drink from without having to top it up constantly. Other cups at this weight will either cost a significant amount more or will hold a lot less fluid. It's handy that you can easily fit a full pint in this cup if you deserve a reward at the end of a long day.
The folding handles and simple design mean you can easily pack this cup in your rucksack and the use of aluminium means it's strong enough you don't have to worry about it once it's in your pack. This version is designed to nest with a 1L Microlite bottle or store a 110g gas canister so packing it with the rest of your gear is easy and the space saving is great.
