It'll look funny, a guy on a new-age MTB wearing a caveman-style backpack. It even has leather holders for a shovel and a pick-axe. According to your descriptions of your commuting route, those could come in handy! ;-) Yup. Will be on one of those routes again later this week :-) -- Regards, Joerg http://www.analogconsultants.com/ |

Yeah, so? It's happening under the straps, right? You sweat there, and straps can cause the irriitation, and can block the sweat glands, which is what causes pricly heat. Try an antiperspirant on the parts effected. It also happens (though to a lesser extent) when not sweating at all. What did help a bit was covering the straps with plastic wrap (like Jeff suggested) under the cotton sleeves my wife already made for them. I tried that out yesterday. Only thing is, that concoction makes me look like a bum. Have to figure out something decent-looking. -- Regards, Joerg http://www.analogconsultants.com/ |

I don't have any bright ideas exactly where to locate the water bladder, but pressurizing provides more location options.

Maybe one of these: http://www.homedepot.com/s/garden+sprayer with a modified hose and coupling. I don't care about that. I could mount a spigot and just use it to refill my handlebar bottle. But there's hardly any space on my MTB. http://archive.fujibikes.com/archive...modelyear=2013 Some day I wan't to use what little space there is in the bottom triangle for a decent battery and tool compartment. On my road bike there's tons of space. The nice thing about the backpack is that I do not have to plan ahead. I can just hop on either bike, whatever is better suited for the ride. -- Regards, Joerg http://www.analogconsultants.com/ |

So, that tells you that you're reacting to something that comes out of the strap (or the foam inside it). Cut 'em off, sew something else on. Or buy a different pack. -- sig 62 |

Goodness! 85% more safety with the cans plus the original 85% safety of the hard hat equals 170% safety.... One world live forever :-) -- Cheers, John B. |
