The worst thing about a dust storm is all the crap that gets into your lungs. Not good. Give me rain, hail, lightning, anything, but leave me out of a dust storm thanks.

I wear cotton. It holds water. When I step into the air conditioning, I have to strip it off within a few minutes, or I'll freeze.

I've started carrying a bandanna around to tie around my mouth (like an old west bandit) with the hope it filters the worst of the dust particles in the storm. I will see how effective it is in the next few days.

I tried not to ride in dust storms and usually rode home after the winds calmed down anyway; but I did carry a bandanna just in case. And on weekend rides I started out in the early morning so I could be finished by 1:00 at the latest. Even then the biggest problem if your riding before the wind starts is those dust devils, it's not a pleasant feeling if one crosses your path while on a bike; and some of those are fairly large-large enough to rearrange your porch furnature if one came through! imagine how that would feel on your bike! So if I saw one heading towards the road I would slow down to let it pass to the other side of road. But when those damm dust devils kick up then you have tumble weeds running about because the dust devil tore them out of the ground. It was not a pleasant place to ride; in fact it was while living there I stayed off the bike for 5 years mostly due to burnout from the racing I had done for 10 years prior, but also from the crappy weather. I hated that area can you tell? Also when you sweat the sand sticks to your body...nice huh? This sand is very fine sand in that region; I knew a guy who lived in Lake Los Angeles and had a new home with the usual dual pane windows-the sand would pile up on the inside window sill and the windows were closed! and this would happen every day when the wind blew-which was nearly every day. You also don't want to get a road bike into the sand along the sides of the road because your wheels will cut into the sand throwing you off.

The cotton shirt thing does not work; you need to get the sweat to the surface so that it can evaporate away, but even then those 100% polyester super dry razzle dazzle shirts still get wet with sweat because of the high temps and that water does try to keep you cool while riding.
