Things to avoid doing in heat:


Drink water early and often.

have had my rallye 2 for 2 years, it's been in daily use the whole time. i find it great and would buy it again - from footpeg riding in central australian summer to rainy commutes in the city, it does the trick. it's what i'm taking trans africa too.
only drawbacks, apart from price:
- like any goretex, it doesn't let moisture out if it's humid weather.
- no water proof pockets, but for those wet commutes i wear a rainsuit over it anyhow.

i would not buy the goretex liner again though. it works fine but was expensive and i've since figured out that my goretex shell jacket works well under it. this allows me to avoid doubling up on gear too.
cheers,
andy.
