Comfortable and absorbent
Very comfortable and absorbent. Happily surprised there is still the ability to use a pad with it.

BRING BACK THE OLD, LESS BULKY GUSSET!!
BRING BACK THE OLD, LESS BULKY GUSSET!! I have 7-8 pairs of the 4.5” period boy shorts with the old gusset. I live in them. I ordered more a year or two ago and immediately sent them back because of the new much bulkier and much less comfortable gusset. Will not buy again until it changes.

We really appreciate your review and continued support. We’re sorry this version of the First Line collection was not as comfortable of a fit as expected. Your feedback plays a big part in helping us refine our selections and we're excited to be debuting a new version of this First Line style early next year.

Not for front-bleeders!!
Hey, tomboyx team! You should include "not for front-bleeders" in the item description since you have not updated the gusset for us!
I wish I had seen the many reviews from OVER A YEAR AGO specifically attempting to inform this company that the gusset is an inch or two too short in the front. Unfortunately, is STILL being made at least 1.5 inches too short in the front today. If you are a front-bleeder, SKIP THESE or you will leak above the gusset because it is STILL TOO SHORT!! I have period underwear from other companies & ALL of them go at least 1.5 inches higher in the front. This is a MAJOR design flaw CONTINUING to be made by this company & I can't believe they've STILL not either changed it or put a "not for front-bleeders" warning in the item description.

Ok but not very comfy or secure feeling
I like the material, but the padding on the crotch part is really big and bunches up and doesn't really sit well.

Thank you for sharing these thoughts with us. The experiences of our customers with each of our designs is so pivotal to drive iterations forward.

Loving these!
My partner gave me a pair they no longer use and I’m so in love. Had to buy more! Best menstrual undies I’ve tried out of 4 other brands. So comfortable and cozy. Easy to clean.

Improved from originals
Fit is the same as my regular underwear with tomboy. 5'4" and 160 athletic build and I wear medium. The larger, more absorbent pad is great and so much nicer than the originals of this style. Very comfortable as all their materials are. Easy to wash and care for. Highly recommended
