I bought the $85 Vargo titanium water bottle to see if it was worth it. The answer? It's complicated. Here's my review.
The CrazyCap 2 ($59, 1.9 oz/56 g) is an ultraviolet water treatment device that takes the form of a bottle cap. At first glance, this little multi-use item seems like the perfect invention for ultralight backpackers on the fly. But how does it perform in the field with its bottle compatibility issues?
