Hmmmm. My last race a couple weeks ago it was really hot so I decided to go
out without the Nomex underwear, just the multi-layer suit. After reading
that story I may never do that again (my previous season I did four races in
100+ weather with full gear on -- not so bad really, especially when impound
greets you with a cold washcloth and a cup of water).
Got no answers on cool shirts. Never tried one. But I've always made sure my
bottom layer (regular underwear and socks under the Nomex undoes) was 100%
cotton, not polyester. I understand the cotton layer is worth another 3-4
seconds of protection.
Arm restraints ... me too. Always wondered why they didn't just put metal
D-rings on them. I saw someone put the cloth loops over the ends of the
shoulder harness, so I tried it. Didn't like it. I decided that was harder
to get loose then when I hooked them on the lap belt. My cuffs slip on, like
yours, and I wear them up around the elbows and will slide off easily (but
in an emergency escape that's an extra move). Makes me wonder about the guys
who have them sewn to their driver suits. BTW, you can get window nets that
are a finer mesh instead of inch-wide straps.
