what is size 4 ? size 2 ?

Always started numbering their "sizes" in addition to their normal naming structure. For example size 4 is their regular overnight pad while size 5 is their heavy duty overnight pad. I've summarized the Infinity sizing below: Size 1 - Regular (wings) Size 2 - Super (with and without wings) Size 3 - Extra Heavy Flow (wings) Size 4 - Overnight (wings) Size 5 - Extra Heavy Overnight (wings) I hope this helps!

Our Infinity Size 4/Overnight pads are approx. 11.8'' long.

does anyone know if they make these in a size for and how well do these work for heavy flow?

Sizes 4 & 5 are for heavy flow & overnight. Size 5 is supposed to be able to hold slightly more than size 4,, but I’ve never tried size 5 so I can’t confirm if that’s accurate. Size 4 does work for me for heavy flows, BUT in my opinion the suggested amount of time it should “last” before having to change it (I believe it’s 10 hours) is a huge overestimate, I would say on a heavy flow day it should last maybe 4 hours (when awake & active) and may last you overnight but will possibly leak when you sit or stand up… but that can happen with any pad regardless of brand or size. These do stay snug & in place, are a good length & are very comfortable to wear, as well as being unnoticeable through clothes. I’ve never had any separation of layers as mentioned by another commenter & Ive been using these for years.

Are these in a box so people don’t know what they are?

They came packaged in a plain brown corrugated Amazon box.
