Does everyone wear only syntethics and wool then?
Why does it get wet?
If you sweat so much that you get wet you wear too much clothes and move to fast. If the shirt gets wet you change it, just like you do whe nyour socks gets damp.
Your clothes will only do 30% the rest is experience and knowledge.
I think you are okay wearing cotton depending on which layer of clothing it is. A base layer should not be cotton because it will get wet from sweat where your bergen comes into contact with your back, even when moving slowly, and then the garment won't dry unless you take it off and dry it. When the sun goes down you will be cold. I suppose it depends on climate.
If you sweat so much that you get wet, besides wearing too many clothes, it can also be because of the ambient temperature and the humidity. No matter how few clothes you wear, or how slow you travel, you will sweat buckets, rather like a sauna, if you are in a hot place.
It may rain hard forcing you to put on your waterproof, but it may still be 35 degrees.
There may be a river to cross. A synthetic will dry faster than cotton. Synthetics are also lighter in weight and remain warmer if wet, due to the above.
Even when driving, your shirt will be wet in the summer from sweating.
It's true, experience and knowledge play the biggest part, but the person will be more efficient if using the correct equipment. If he's cold and wet, his morale will be low.
Going back to Mear's kit, subtle advertising and sponsors has a lot to do with the vast array of items used during his program. It's all good kit of course but even if the programs are shot over several weeks, if it was you or me I'm sure we'd still end up using the same gear because we simply don't have the amount he does.
