Thus far, my favorite period pants!
I needed something that could get me through a 3 hour commute (with no access to bathrooms) which includes a hike up a steep hill.
I have already overflowed out of overnight/heavy/long disposable pads during said trip, and frankly I'm tired of it.
I wore this pant for five hours, including an hour long walk and they still hadn't soaked the whole pad yet (there were still dry areas at the front and back of the padded part). I'm amazed at how much these pants absorb!
I have another brand of period pant that was soaked and sticky after less than 5 hours.
Flux pants are by far my favorite, and are the only brand that offers a pant to hold so much liquid.
The heavy flow line has several styles to choose from, whereas my other period pants only had one style of heavy flow (at the the time I bought them).
Flux are also the most comfortable and soft period pants I have found.... even the stitched seamed areas are soft (most others are scratchy!)
I am watching for a sale so I can fill out my period pant stash using only Flux (and ditch the other brands)
And international shipping only took about 3 weeks via Royal Mail, which was surprisingly fast. I also appreciated that tracking information was provided.
