At last, time for Smarter Backpacking
As many readers already know, I have been quite busy this fall with my first book in English. I am happy to say that it is now available at Amazon. But books are a plenty, so what's with this one?
Weight on your feet
In several books, including the soon to be published Smarter Backpacking, I have written that it is five times as energy consuming to carry something on your feet, compared to carry it on your back. This makes some people irritated, so I have collected some of the scientific articles that support this rule of thumb. Read and judge for yourself.

Breathability of fabrics
Gortex is of course the king, but there are many pretenders. And quite a few of them have adopted the suffix -tex. In a feeble attempt at humour I call all these 'waterproof/breathable' fabrics 'Mextex'. Not popular with some people who do not think you should treat such a serious subject in such a frivolous way. But how breathable are these fabrics, and others used in outdoor gear? I've consulted Chris Townsend on the subject.
