Surprisingly Great Quality

I mainly wanted to try out the pocket but was pleasantly surprised by how comfortable the underwear material was. I personally think the thighs can be tighter so the pocket stays closer to my body and doesn’t move around as much when I’m running. That’s just personal preference though. Overall 10/10 would purchase another pair.

Thanks for the thoughtful review! We’re glad you enjoyed the comfort and material quality. We truly appreciate your feedback on fit and pocket stability during movement — it helps us continue improving. Thanks again for trying PREDICTION!

I love the pockets

I love the pockets. I think it should be a little longer going down your legs and the waistband should be a little wider all in all very comfortable fit very soft, cool and I am pleased with it for now, but I do need some upgrade. Make them a little longermake the way Make the waist a little wider.

Thanks a lot! Glad you like the pockets and comfort. Your suggestions are very helpful as we continue improving.

Luxury Fabric, Perfect Fit, Unreal Quality!

I cannot say enough good things about the AD ASTRA Dual Pocket leggings from Prediction! The quality is absolutely incredible — the fabric feels luxurious, holds its shape perfectly, and looks just as amazing after multiple washes. But let’s talk about the real win here: these leggings make your butt look phenomenal. The fit is so flattering and sculpting, I get compliments every single time I wear them. Perfect length too — not too long, hits just right! The dual pockets are a game changer as well — actually functional and don’t ruin the sleek look. If you’re on the fence, just buy them. You won’t regret it. 10/10, already planning to grab another pair!

Thank you so much!
This truly means a lot to us. We’re glad you’re enjoying the fit, feel, and overall performance and especially that the pockets are making a real difference. Really appreciate your support.

Love them. Super comfortable and perfect fit for me. The built in pocket is very handy for medication that I don’t want to carry in my pants pocket.

Thanks for your review! We’re happy to hear the fit is great and the pocket has been useful for you.

Is there an opening in the front for exiting when bathroom necessitates?

Team PREDICTION

Thank you for your interest in our product. Ad Astra does not have a traditional front fly opening. It is designed with a smooth front for comfort and structure, and many customers find it easy to use.
