It would be impossible to complete any mission without drinking water, and that is why we at US Navy SEAL Store sell Navy SEAL canteens. Our canteens are highly durable and fit perfectly into carry pouches. Our Navy SEAL canteen cover is what you'll need to securely carry your canteen along with you to keep it insulated offers you a great grip. If you ask any veteran of the Iraq War how important his canteen was to him when out on missions, he will undoubtedly tell you that without his trusted canteen, he may not have survived. When you are subject to 100 plus degree heat, dressed in a heavy uniform for hours on end, every drop of water is precious and nearly sacred. It is absolutely imperative that you carry a very reliable canteen-one that does not leak and one that will keep your water fresh. Our Navy SEAL canteens are built extremely tough. They can be dropped, bumped and thrown without doing any damage. As you know, when you're out in the desert, forest or climbing foothills in the mountains, you are very apt to drop your canteen. We also are proud to sell our Navy SEAL canteen cover which provides added insulation for keeping your water cool and also gives you a great grip when reaching for a drink with sweaty or wet hands. Choose from our plastic canteen or perhaps you'd rather carry our canteen that is made of rugged polycarbonate which also prevents the buildup of smell and taste.
