Our group of four to six people takes a yearly fly-in fishing trip on a remote lake in northern Ontario. I'm in charge of water filtration.

After news reports revealed that our trusty Nalgenes contained a hormone-disrupting toxin called bisphenol-A, or BPA, drinking out of anything suddenly seemed like a high-risk activity.

I'll soon be living in my tent for six weeks in Tanzania, and I’m looking for a lightweight, compressible, and not-too-pricey sleeping bag that will do well over that stretch of time.

Swooping through your first full-rail turn on a Hess surfboard requires a suspension of disbelief. This thing is made of wood? Hand-constructed from sustainably harvested poplar, cork, and amapola by San Francisco shaper Daniel Hess, it’s a piece of art as much as a performance wave-rider. Unlike the clunky wooden…

I have just acquired a Quest Starlight tent that’s in pretty good shape. But, the older fellow who sold it to me said that it likely wouldn't hold up to several days of rain.

I find mummy bags to be really confining. I understand the point, of course, but I'm a side sleeper, and I like to lay "can-opener-style." (You know, with one leg pulled up and the other straight.)

I want something that will show my cadence, heart rate, miles, elevation, average speed, and time, play my music, and set up tent (OK, not that last thing). Can you suggest a tool that does it all? Rich Spanaway, Washington

I took a nasty 300 foot slide on a hard-packed, black diond slope after slipping while snowboarding. On the way down I intersected with a tree and have lived to tell the tale. I would like some advice on an ice axe or smaller device that I could use to stop myself in the next hair-losing slide like that. Any ideas? Kirk Olivehurst, California

The new Vectrix, the only highway-legal electric bike on the market, isn’t perfect.
