I've just received the bag recently, but I haven't had a chance to test it yet. So I can't give an opinion on its effectiveness. I'll do a reddit as soon as I've tested the product!
But the quality of manufacture is there and the bag seems to be of high quality!

Dobrý den, rád bych si koupil polštářek. Vy nemáte žádný ve vašem portfoliu. Proto bych potřeboval vědět typ ventilu na vaku, abych si k tomu mohl koupit adekvátní polštářek.
Dobrý deň, ďakujeme za Vašu otázku. Ventil na vaku nie je konkrétne štandardizovaný. Pri výbere vankúšika využite prosím fotografie produktu na produktovej karte. Prípadne kontaktujte naše zákaznícke centrum na [email protected], ktoré Vám následne bude vedieť zaslať na požiadanie detailnejšie fotografie ventila. Váš ZAJO tím
