Don't know if I will get a bottle holder or not. but it would possibly be a good addition to the pack. Thanks for the resend.

Did you get it this time?

Yup I did and thank you. I wonder if the sidewinder would be more beneficial IF you got the room can handle the 1 pound weight. I been looking at it and found it for just a tad under 100.

That link I sent you has the sidewinder for $89

I would like to feel the build quality before I make any suggestions though. Combining electrical and mechanical seems like you are doubling the possibility of failure. But, it may be build like a tank.

I had thought of that, but HOPEFULLY the mechanicals ARE done right. Thanks again.

Plus, if you are going to carry something that big, you might as well go for a traditional filter. The whole point of the Steripen is to conserve weight and space, while giving up true filtration.

Yeah I had thought of that as well. Just trying to get around having to have two different devices. I figured you could always put a folded up bandana or coffee filters over the bottle mouth, plus it says it has a "Prefilter" not exactly sure how that works, probably a screw on cap.

For those interested in the steripen Sidewinder, here is a pic of the "Internals".

You can see the prefilter in this pic. It is the same as the one with the Sidewinder. It just screws on the mouth of the bottle and is only good to get the dirt out.


The good thing about the filter is that it prevents the untreated water from getting all over the mouth of the bottle. This is one of the criticisms of the steripen as it doesn't treat the water that dipping a bottle into a creek will get on you bottle.

I still suggest wiping the rim the best you can before treating the water inside.

I was wondering how they were addressing that. I just figured it would be better to use a separate bottle and pour the water into the one you were going to use the purifier on wheather it be the SteriPen or the sidewinder.
