These underwear are very soft! The fabric is very breathable, which seems like it will be ideal during that time of the month. I purchased a single pair at the same time as this set and everything came packaged together about a month after purchase (Shipping has been slow in Canada due to the pandemic and they still came within the suggested delivery date). I purchased size 3XL and have a 38” hip, normally wearing a US Medium. I would suggest if you have “thick” thighs to go up a size as the leg holes might be a little tight. Will update with reliability of leakproof.
The packaging is small and neat. Underwear colours are rich, fabric is super soft to the touch. I can't wait to test it's effectiveness to prevent leaks.
