Each have their benefits and drawbacks. Nalgene bottles are made from the sturdy Tritan plastic. Light and shatterproof, with a high capacity and easy-fill wide-mouth. They aren't fireproof so cant be used to boil water or cook in. The SIGG bottles are aluminium with an internal plastic coating and a finely threaded cap I've found to be delicate and prone to thread stripping. The Aluminium bottles are sturdy but ding and damage easily. They also do not support cooking or boiling due to the lining.

Combining time tested design with the high-strength to weight ratio material results in a light weight yet durable mess–kit. Perfect for those counting grams on the trail and people who break gear, like me. Both Canteen and cup can be heated and used to boil water or cook food.


The canteen has a jutting rib around its mid-line which corresponds to the lip of the cup, to seat it. when nesting the cup lid is obviously left out, but I found that any pouch i could fit the canteen and cup in will also fit the lid in the bottom, ready to deploy to be a lid your cup for bean or noodle cooking. I don't know wat purpose that rib serves, except to possibly prevent rattle between mug and canteen on maneuvers.
I found the canteen had an off-flavor from manufacturing so I needed to give it a good wash and rinse out. Kraken rum worked nicely. The mug didn't have any such problem and cooked several meals without issue, and relatively non-stick and was easily cleaned.
Over-all I am really happy with this set, they're light, rugged as all get up, cook well and not bulky at all. I really like the traditional form factor and compact design for considerable volume capacity.
