Great service and product.
I ordered Hiro trausers and am really happy with them. Already had Hiro light and wanted another pair but unfortunately they weren’t available in my size, so decided to try Hiro instead. It was super fast delivery, I’m really happy with the product- they look great, feel maybe not as free and airy as the HIRO light but still very comfortable and stretchy. This is my second time ordering from 3rd rock and I would do again. Already recommended the website to my friends.

Great!
Love the durable fabric and the color, but the waist runs a bit small despite the rest fitting perfectly per the sizing chart. Still usable as long as I don’t eat a big meal! Please make in more colors!
