I have been a fan of Right Guard for quite sometime, it seems that the products do exactly what they say on the tin.

This Extreme Sport addition to the product line works harder to keep back sweat at those times your body is physically active. It even works well during the day when you're not doing strenuous exercise so it's got the best of both for each situation. Though the smell isn't brilliant, it's sort of sweat and musty (though it's not too obvious) it's something that can be put up with briefly until the smell dies down after half an hour or so.

Right Guard have always competed on price and at around £1.50 you can't go wrong. Just the other week I saw an offer on two of these for £2, that's even less that what you could pay for other brands.

The only downsides with this product is that they seem to run out rather quickly, and I'm not quite sure why. Perfect if you need that boost to prevent you sweating out in the field.
