our word for it.
I'm really excited that I received the garments and was able to use them for training. it is super impressive, I was really mind-blown.
I am also interested in trying the calf sleeves so I will plan on ordering those as well.
Thank you so much for your help, and congratulations on such a cool product. I am really excited to continue using it when I'm training.

We are really happy with the sports bras so far! They feel very comfortable to wear, and we barely notice them during the sessions, which is impressive considering how much more weight we are wearing.
We have only tried them 3-4 times so far, but we are looking forward to testing them more.
We will get back to you with more detailed feedback once we’ve have tested more.

Now I’ve received the shorts and wow, what a material! I recorded an audio file with my thoughts when I opened the package and tried them on for the first time.
It really feels like there’s great potential in this material.

I used them for a few days before the holidays and it was easy to forget they were there after a few minutes, only after I removing them I truly felt the change.
Breathable and slightly tight atm I am happy with my purchase.
