Excellent backpack, I can say that the materials are great and the vacuum seal is effective! I absolutely recommend it!

The bag is awesome, good quality and design, i recommend it warmly. The only issue is with vacuum pump tips provided. They are either too small which blocks the valve or too large.

All works perfectly, color is amazing, waiting forward for some weekend travels. Thank you for your clever product 🌸

Looks good, vacuum sealing was stable for the 2-hours test i tried

The backpack looks high quality. Buy a lot and allows carrying much more clothes without that function. Used on Ryanair without problems. I'm considering getting another one. Ryanair's focus is on rigid ones. If they weigh mine, it would have a problem, but visually it is so small that there is no problem.
