Price is very high as compared to quality of the product
Hello Kousatav
Thank you for your valuable review. We are sorry that you were not satisfied with the product.Trek 100 Ultra compact cap is a new innovative solution of the issues that we face with a trekking cap like the size of head and where to keep while we're not wearing it. the manual tying system fits any head size and since it is compact it can be kept in the pocket of your trek pant while you are not using it.
I hope the information helps.

Brilliant idea. Saves running/walking with sunglasses on all the time, the cap is so light that I've taken it everywhere. Takes a little practice to get the hang of tying it different ways but it's worth it. It will be very useful in the summer.

What makes my cap eco-friendly?
The cap's fabric is 90% recycled polyester, made from recycled plastic bottles.
Compact design
The cap's visor is made from thermoplastic elastomers (TPU), which combine the elastic properties of elastomers and the mechanical properties of plastic. The result is a sturdy, flexible, shatterproof visor!
How do you measure a fabric's quick dry capacity?
The product is machine washed 3 times then line dried, then we immerse it in water and measure how long it takes to get back to its pre-wash weight. This cap scored an impressive 4 out of 5 stars, returning to its pre-washed weight between 80 and 120 minutes after immersion
