As well as lights and blades I seem to collect bottles. I like to have my own reusable and reliable hydration source to hand. In my EDC bag, my desk at work, in my car and so forth. My usual go to bottles are my wide mouth Nalgene bottles and my venerable SIGG bottle.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.
A solution I found is the Heavy Cover US GI Style Titanium Canteen Mess Kit. Over the last hundred years or so the US GI style canteen mess kit has served millions of military service members as well as millions of outdoor enthusiasts. Originally made from tin, aluminium or stainless steel or plastic, the Heavy Cover model replaces this with titanium. The kit is comprised of a 37oz (1.1L) canteen with Tritan Plastic and Titanium Canteen Cap options and a nested Canteen Cup 23.7 oz (0.7L) and lid, also titanium.
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.
Made from 0.5 mm thick titanium, the Canteen with Tritan Cap weighs a slight 6 ounces (172 grams) and the titanium Cup Lid weighs a mere 4.8 ounces (132 grams). As well as being exceptionally light, titanium has the advantage of being biocompatible (BPA Free, nontoxic to the human body) provides a non-porous, non-stick material for easy clean up when cooking. being thin walled and a rapid heat conductor , less gas/fuel is needed and you get a faster boil time than with steel or other pot materials. It is anti-corrosive and will not rust. The mug has folding wire handles to assist in cooking and handling when hot.
The titanium cap of the canteen features a wide, thick thread to ensure ease of opening and removal as well as maintaining a tight seal and resistance to incidental damage. The lid itself features a titanium D-loop for clipping to a belt or pack, dummy-cording or perhaps even suspending over fire to boil water (beware steam and pressure build ups!) The canteen neck and mouth are quite wide which make for easy filling and drinking. The titanium cap sits quite high above the lip of the opening, I don't know why. It is hollow and floats, unlike the tritan lid which sinks like a rock. The titanium lid has a flat-folding wire lid loop for retention or for use as a float.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.
