Waterproof backpack or water-resistant backpack, are they the same? You may have the same question like most of us. Well, there are a few differences between the waterproof backpack and water-resistant backpack in material, production technology. Let's talk about them separately.
Waterproof backpack means the backpack can be submerged. So if a backpack is labeled waterproof, which means you can take it anywhere or even diving since this backpack can completely submerge in the water with keeping inside dry. A waterproof backpack is usually made of heavy duty PVC or TPU coated fabrics. Those fabrics have good waterproof features that can stop water getting in at most harsh conditions. You can take the waterproof backpack to kayak, raft or cross a river. In production technology a waterproof backpack is fully welded seams by high frequency not sewing and taped, which means the seams can bear too much water pressure without pop up. And even the zipper—a zipper used on waterproof backpack must be a waterproof one. The zipper is usually welded to the backpack in order to keep the water out. Some backpacks are welded with air-tight zipper in order to gain better waterproof performance. Airtight zipper is much better than the water-tight zipper.
Motxilles-resistents a l'aigua
Les motxilles-resistents a l'aigua només són a prova d'-esquitxades. Només poden protegir el vostre equip de la pluja o les esquitxades. Les motxilles-resistents a l'aigua solen estar fetes de niló o polièster, que simplement es teixeixen-con un recobriment aplicat a l'esquena. A mesura que passa el temps, el recobriment s'esborra. En tecnologia, les motxilles-resistents a l'aigua es cusen i es col·loquen amb costures. Les cintes poden aparèixer a mesura que passen els temps.
Així que podeu tenir una idea de com triar una motxilla. Si vols fer caiac, ràft o cross river has de triar una motxilla impermeable. Si només voleu descobrir la ciutat o fer senderisme durant el cap de setmana per oci, n'hi ha prou amb una motxilla-resistent a l'aigua.
