You might wish to read this alongside my post on gussets as in particular I’ve covered external double gussets there in more detail. There are a few different options for the style of leg elastics on nappies. Effectively they are all the same, so don’t worry about which one to get. This is more a quick breakdown in case you’re wondering what other cloth users are talking about.
Standard elastics
The most common. These will feature on most nappies. Normal offer decent containment and are hopefully gentle on little legs. Some will also feature an internal double gusset, again see my gussets page for more on that.
Rolled elastics
A personal favourite of mine. Normally much gentler on the legs, so less sock marks. Can often mean you just need to double-check the legs to ensure the elastic has rolled inwards and nothing is sticking out.
Semi-rolled elastics
This is one I’ve recently discovered. I’d call it something of a hybrid of the above two. From the small sample which I have used, the elastics are very gentle like the rolled elastics. They roll in when worn, but don’t require the same due diligence of checking that everything has rolled in correctly.
