AMKs’ BPA-Free S.O.L. Survival Water Bottle

AMKs’ BPA-Free S.O.L. Survival Water Bottle – The Only Bottle That Can Save Your Life Even When It’s Empty!

The recent admission from SIGG that the aluminum bottles it had produced prior to August 2008 contained the chemical Bisphenol A (BPA) has once again put into sharp focus the safety of all water bottles. There is one way, however, you can be sure your next water bottle does not contain BPA or any other potentially harmful chemicals — that’s to select one made from stainless steel, like AMK’s new S.O.L. Survival Bottle.

Made of tough food-grade, 201 stainless steel, the BPA-free S.O.L. Survival Bottle will not dent nearly as easily as aluminum bottles, which contain inner linings which, if broken, can leach chemicals that can potentially contaminate water. AMK’s S.O.L. Survival Water bottle will hold up to 750 ml of water, but its much more than just a liquid container.

Unlike most water bottle manufacturers, which emblazon the exterior of their bottles with a logo or design, AMK used this otherwise ignored real estate to offer valuable information on everything related to water and hydration.

Printed on the outside of the bottle are a multitude of tips and facts — ranging from the useful (“How to find Water in the Desert”; “How to Purify Water”) to the novel (“Number of years it takes for a plastic bottle to decompose”; “Number of plastic bottles thrown away each hour”) — which lend the S.O.L. Survival Water bottle an added level of utility not found in competitor bottles. In reality, it truly is the only bottle that can save your life — even when it is empty!

The S.O.L. bottle is also safe to boil water in and comes with a sturdy screw top and carabiner, allowing you to attach it to your backpack for your next outdoor excursion.

Backcountry Grub: What’s Safe to Eat and Drink?p

In October, a solo climber on Washington’s 12,276-foot Mount Adams fell on Suksdorf Ridge, and broke his ankle. It’s just what every climber fears: being alone on a high mountain with a disastrous injury. Unable to walk, he dragged himself down the snowfields. After five days and nights, he was found at 6,200 feet suffering from frostbite and dehydration. He survived on creek water and an eclectic mix of creepy crawlers: ants, centipedes, spiders, mushrooms, and berries.

Sooner or later, if you spend time outdoors, you may find yourself without food or water on a wilderness outing; hopefully it’s just a short distance to your car and you are uninjured. But in survival mode, if you are lost and injured, you may need to eat and drink from the wilds.

You can live several weeks without food. But you won’t last much past five to seven days without water, even fewer if you are in the desert or at high altitude. Finding water is a paramount priority.

Drinking from creeks, like the Mount Adams climber, is probably a risk worth taking in prolonged survival situations. Yes, you can get protozoa infections like Giardia and Cryptosporidium, as well as bacteria and viruses. However, it takes just one day for you to begin to become incapacitated from dehydration.

When you find a source, ideally you should have a means to purify water before drinking. That means boiling, filtering, or chemical treatment. I carry water purification tablets for emergencies: they are compact, light, and easy to use.

Remember, when in the mountains, eating snow can cause hypothermia, because you need to use vital calories to melt it in your mouth first. So you should carry a lightweight backpacking stove to melt water. When in the desert, locating water can be extremely difficult, so if you find a source, consider staying put until you are rescued. If you do get a gastrointestinal infection from drinking backcountry water, see your doctor A.S.A.P.

As for food, if you can’t identify it, don’t eat it. You can get seriously ill from toxins and infections. My friend Greg Davenport, a survival expert, said critters with eight or more legs like centipedes and millipedes are often toxic. He recommends sticking to insects, which have some nutrition, but not much. A typical 100 gm (3.5 ounce) serving of fish, for example, yields 22 g protein, 1g fat and 0g carbos. The same weight of crickets yields 13 g protein, 6 g fat, and 5 g carbos. But that’s a big pile of crickets to scrounge for.

Wild plants—leaves, roots, bark, nuts, seeds, and berries— can be energizing or deadly. Use caution: even a small bite can cause stomach pain, nausea, vomiting, diarrhea, and rashes. Mushrooms can kill you. Davenport said aggregate berries, like thimbleberries, raspberries, and blackberries, are generally safe to eat. Purple, blue and black berries, such as wild huckleberries and cranberries, are 90% edible. Red berries are about 50% edible, so it’s probably best to avoid those, as well as any berry white, green or yellow, which are not edible.

Remember: always take enough water and food (an extra bottle of water and a few extra energy bars) to spend at least one unexpected night in the wilderness. And stash some water purification tablets in your survival kit.

MYTH: You need to boil water for ten minutes to make it safe to drink.

FACT: Any water brought to a boil, even at high altitudes, is safe to drink.
