How I examined

I’m no stranger to interval underwear and different “different” interval merchandise (The place my menstrual cup followers at?), so I jumped on the probability to jot down this information. Once you’re in your interval, staying dry and comfy are the highest priorities, so I judged each pair of those underwear via that lens.

I first examined all the above underwear for match, to find out if they’re true to measurement. That largely concerned loads of attempting them on, sporting them beneath pants to see how cumbersome or slim they had been and if you happen to may see panty traces.

Subsequent, I examined the absorbency to see if it lived as much as the claims. Since it might take me properly over a yr to check every considered one of them whereas on my interval, I developed an simply repeatable methodology in my dwelling lab (additionally referred to as the kitchen).

I washed every pair of underwear in keeping with the label and air dried. You’ll need to wash your interval underwear earlier than you put on them for the primary time to take away any starch or different chemical substances used within the manufacturing course of. Air drying is essential to preserving the underwear’s absorbency — cloth softener or dryer sheets can go away a movie behind that doesn’t permit moisture to cross via.

Subsequent, for every pair, I checked what number of tampons’ price of fluid they’ll maintain and transformed that quantity into millimeters. This isn’t actual as a result of there’s some variation in tampons throughout manufacturers, however on the whole, one common tampon can maintain 5ml of liquid.

I slowly poured that quantity of water over the gusset of the underwear to see how shortly it absorbed and if any water leaked. I left them for half-hour after which checked to see how dry they had been after absorbing the water. Some had been simply as moist as after I began the check, others had been dry sufficient to comfortably preserve sporting. 

I’ll caveat that this isn’t an ideal check. Menstrual fluid normally leaves your physique slowly over the course of some hours, although some folks expertise quick gushes all through the day. A number of the underwear I examined didn’t take in the whole quantity of water instantly and/or leaked, however that doesn’t imply they wouldn’t work to your interval. In case your circulate is regular over the course of a day, interval underwear may have time to soak up it slowly, which can decrease leaks.

In the event you cross a number of clots throughout your interval or expertise repeated gushing/flooding, interval underwear may battle to soak up fluid and preserve you feeling dry.
