How I examined

I am no stranger to interval underwear and different “various” interval merchandise (The place my menstrual cup followers at?), so I jumped on the likelihood to write down this information. Once you’re in your interval, staying dry and cozy 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 dimension. That largely concerned loads of attempting them on, sporting them below pants to see how cumbersome or slim they have been and for those who might see panty strains.

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

I washed every pair of underwear based on the label and air dried. You may 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 vital to preserving the underwear’s absorbency — cloth softener or dryer sheets can go away a movie behind that does not enable moisture to move via.

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

I slowly poured that quantity of water over the gusset of the underwear to see how rapidly it absorbed and if any water leaked. I left them for half-hour after which checked to see how dry they have been after absorbing the water. Some have been simply as moist as once I began the check, others have 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 individuals expertise quick gushes all through the day. A number of the underwear I examined did not soak up the complete quantity of water immediately and/or leaked, however that does not imply they would not work on your interval. In case your move is regular over the course of a day, interval underwear may have time to soak up it slowly, which can reduce leaks.

When you move 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.
