Logically speaking you could consider either (a) addressing the cause of your sweating or (b) just manage the symptom itself. I think most people would go with route (b), and on this forum that means more kit!
(A) ADDRESSING THE CAUSE OF YOUR SWEATING
I think the obvious causes of sweating are (1) it's hot outside, (2) the batsman is nervous/ adrenaline is pumping, or (3) you were just made that way.
(1) Now bear with me on this, I did see a program on the BBC I think where they were trying to cool down sportsmen/ women in the most efficient way to maximise their performance and endurance. What they found was that by cooling their hands they could cool the rest of their bodies and core temperatures far better than any other technique. So for added benefits, how about keeping 2-3 pairs of gloves in a cooler box with your drinks and ice packs. Sounds naff but might be a worthy and relatively cheap experiment. Alternatively keep your hands cool with cold drink before the innings!
(2) Not sure you would want to reduce your nerves or adrenaline though if you're nervous to the point of being sick, as I have seen, then you could go down the beta-blocker route as many people use for driving tests, and reportedly so snooker players or darts players may use to keep their hands steady. It only controls the physical symptoms of stress, and not the mental ones, and it would have to be bad to warrant seeing your doctor about, and it's debatable whether he/ she would agree to prescribe in that circumstance unless it was affecting other activities of daily living. Plus beta blockers do have side effects, potentially brewer's droop amongst other things! Other options are relaxation techniques. There are some in PitchVision I think.
(3) If you're made that way (sweaty), then go to plan (b).
(B) MANAGING THE SYMPTOM, i.e. SWEAT
(1) As has been said above - and as would be popular on here you could just buy more kit- gloves, inners, forearm sweat bands
(2) Try Anhydrol roll-on to your palms over a period of weeks to reduce your sweating
(3) If you're spending £200 on gloves - have you considered IONTOPHORESIS and even Botox to your hands? Not saying I would, but just asking the question.
In summary, try Anhydrol roll-on or experiment with cooling hands/ gloves pre-use
Perhaps I should have just said that at the beginning.
