Pros: reusable, saves money, pretty, comfortable -feels like just undies, customizable for flow
Cons: can be bulky, cost more than other cloth pads,
If you've not used cloth pads before, I'd certainly suggest GladRags or similar.. mainly because these types you can alter the thickness to suit your personal output.
They can be used with no filler as pantyliners or with 1 or more fillers to accommodate your flow heaviness. The customizable nature of them are great for females switching to cloth because there is a slight learning-curve to the amount of cloth is needed to absorb properly... it is Not the same as using a "regular" pad. Normally a cloth pad does not need to be s thick or bulky as a standard pad.
Cloth pads tend to be much more comfortable... it feels like underwear against your skin rather than the plasticy/non-cloth feel of single-use pads. Also, no mishaps of adhesive areas getting twisted and sticking to you. -That sweatiness and/or chaffing that occurs at times with the plastics of other pads isn't there when using cloth.
They also definitely save you money over time.
The cloth patterns are varied and are just more pleasant to have to look at and use than standard pads.
