I know that everyone is switching to stainless steel water bottles and canteens now because plastic will kill you. Will gave me a stainless steel one and I find that it scratches and dents pretty easily, though I still thank him for the gift.
However, after an experience yesterday while hiking with Joel (not the one who writes for this blog, he was riding a bike) and Johanna at Peoples State Forest. I think that Nalgenes still have their place.
This bottle:
Fell off this cliff:
No damage! It even spectacularly bounced off a rock and went like 20 feet up in the air. That's actually a post cliff-fall picture of the water bottle. I'm totally impressed. Stainless would have definitely broken.
I recently did the switch to a Sigg and I'm pretty disappointed with it. Once this kicks the bucket (I'm giving it maybe 6 more months) I'm going back to nalgenes.
ReplyDeleteI think as long as you don't leave water in them for three weeks, they won't kill you.

ReplyDeleteMore than six billion pounds of bisphenol A are produced each year1 and 95% of Americans tested by the Centers for Disease Control now excrete it in their urine.2 In laboratory studies, bisphenol A alters egg development in exposed fetuses and increases the risk of genetic damage in the next generation, thus providing evidence for multigenerational effects.3 In laboratory animals exposure to bisphenol A profoundly affects the male reproductive system, with adverse changes to the testes, testosterone and sperm production.4 It increases prostate and breast cancer risk, alters brain development, and causes earlier puberty and obesity. Researchers found that women with a history of recurrent miscarriage had higher blood serum levels of bisphenol A than women with successful pregnancies.5 All of our participants who submitted urine samples had bisphenol A in their urine, and more than half had it in their blood. The levels of bisphenol A in the blood and urine of our participants are within the range shown to cause effects in laboratory animal studies, including impacts on cell function.6
