    Not feminine

    They have great quality, but they are too boxy and masculine.

    Have changed my life. Have ordered a second pair. Just live them. I was very skeptical, but am a believer now. Wash up great! Love my underwear as well. So glad I didn't buy Everdries.

    I love my Dream Boxer

    I love the Dream Boxer I bought. It is supremely comfortable all night long and I can sleep all night knowing that it is leakproof and will absorb any leaks, since I tend to leak a little while asleep. Best of all, I can wear the boxer with an oversize t-shirt instead of a nightgown and wake up feeling good in the morning. I'll probably buy another soon.

    Love!

    My period is short and heavy. If I’m tossing and turning during the night, there might be some leakage so I looked for something like this that was super absorbent but also comfy. Plus because they are boxers it’s not seen as a period products just with appearance. I’m typically a medium in underwear so I sized down to a small so there would be no gaps and no chance of leakage. Definitely absorbent enough but I might go down another size because it’s just the tiniest bit loose. I don’t think I really looked at the specs when ordering so make sure you do! I’d definitely recommend though and am probably going to buy another in the near future.
