Did you think that the best part of Memorial Day weekend was going to be the extra day for watching Netflix? Think again — or should we say, THINX again? The menstrual underwear company is having a rare sale — everything is 30% off! — and it wants you to “treat your V” by skipping tampons and using absorbent undies instead, all in honor of Menstrual Hygiene Day (yes, it’s a thing).

According to the company’s website, THINX uses technology (exactly why we need more #womenintech) to offer “anti-microbial, moisture-wicking, absorbent, and leak-resistant” panties for that time of the month, and they really do work!

These are some of the items on sale this weekend:

The Training Shorts are on sale for $45.50! (Usually they’re $65.) They come with built-in absorbent underwear, so you can just throw ’em on and go for a jog when Aunt Flow is visiting.

The Hi-Waist period panties are on sale for $26.60 (they’re usually $38), and they hold two tampons’ worth of blood! Because it’s all about the blood, really.

The Hiphuggers will work on your HEAVY DAYS! And now you can get a pair for $23.80 (instead of $34).

Comfy Boy Shorts are available for $27.30 (normally $39).

And the brand’s period-proof Leotards are selling for $42 (normally $60).

And there’s even more good stuff on the site!

Happy Memorial Day weekend, Menstrual Hygiene Day, and THINX sale, everyone.
