I wear these all the time. Helps with cramps but also chronic back pain and discomfort.

The back could be 3" higher to cover more of my lower back, but they do a good job. The shorts are advertised for "period pain". I wanted something to go walking in when the weather gets cold. I still have to try out the heating function. They are very stretchy, so having a penis isn't a problem.

Here's what my wife told me.

I was surprised at how comfortable they were and how quickly the heating element heated up. It was infinitely better than having to hold a heating pad and I will be recommending them to others. They're also cute.

Honestly, I have been suffering from period cramps since I first started my period and only resort to taking Midol at my breaking points, however, now that I have discovered these amazing miracle shorts I'm going to be able to handle each month with more ease now!! I cannot believe these weren't made sooner and I'm so in awe of how well these shorts and the heating capabilities perform. My first two days of my period typically are the most pain I experience, so having these shorts are definitely going to be so handy!!

Sufro mucho de cólicos desde chica, en esos días no podía hacer absolutamente nada más que estar tirada en mi cama y esto me ayuda muchísimo, es un excelente producto y la calidad es increíble

They have definitely made a difference during my periods. I will never go back to heat pads!

These shorts are so perfect for the time of the month! I have really bad cramps and these help soothe the pain with ease

highly recommend, these shorts are a total game changer for period cramps or staying warm.. everyone woman needs a pair!! such a good gift for yourself or your loved ones🤍

I got my shorts (XL - I’m normally a size 14), and they are AWESOME! Where has this been my whole life? They heat up so quick and provide so much relief (or just a luxurious lounge). I know what I’m gifting my friends this year.

These shorts are a life savor for me! I struggle with bad cramps and these heated shorts do just the trick! Also, they are washable! So you can reuse them! Odor resistant! And they stay heated for 2-4 hours! Truly amazing! Lastly super comfortable to wear!

These are so comforting to wear. I found the sizing accurate. They are comfy and cosy and have made wfh, sitting at my desk all day so much bearable. What an awesome analgesic. Thank you so much.

Stop what you're doing. Like, stop even reading the reviews, and go buy yourself a pair of these shorts...NOW. I'll wait....

Okay seriously though... these shorts are not only incredibly comfy to just wear, they are a legit built in heating pad. SO easy to use and I love the convenience of not having to be stuck in bed attached to an electrical cord. I can just pop in the battery, hit the button and go about my day, all while enjoying the soothing heat for both my cramps and lower back.
Trust me, you want to grab a pair!

I recently got the Sundaze period shorts. I liked that it was like a heating pad that you could wear around the house. It makes periods a little more bearable.

I love how stretchy and soft these are! They are very sensory friendly, and not too heavy at all with the battery pack. They heat up very fast, and definitely help with my back aches and cramps <3 I highly recommend, especially if running errands! I love that you can just wear some baggy jeans over these, and also purchase a secondary battery pack to extend your use!

These are a game changer for period cramps and pain! I wore them skiing to keep my bum warm too! Honestly recommend to anyone who needs period relief!
