Hi Jim
There are some reviews of the Borneo trip in the Reviews section. I did a review following my trip in May 2016. You do not really need any warm clothes whilst there but obviously you will need something warm when you travel to Borneo and on your return journey back home as it will be chilly here in November. Take a waterproof if you have one or you can easily buy a cheap 'throwaway' poncho whilst there. I personally did not take any mossie spray, but if you are the one who gets bitten then do take some. Also take any prescribed medication. I usually also take paracetamol, strepsils, cold remedies, immodium, plasters etc. There were no hygiene problems encountered by me. This is a lovely trip and you will have an amazing time. Quite a few of us also did the Singapore add on.
Regards
Jaya
