Whether you’re going camping in the winter, kayaking through white water rapids, or trekking through the rain, you’ll need a waterproof backpack to keep your belongings safe and dry.

Many people protect the contents of their bags from water by lining them with plastic bags (or two) or by using commercially available waterproof pack liner.

Most outdoor gear shops and department stores sell pack liners, which are very inexpensive. Even if they do, you should think about how useful they are in keeping your bag dry.

The advantage of using these bags is that they are designed to keep water out. Sure, it won’t keep your bag dry if it gets wet, but even if it’s drenched, the contents will stay dry. The only issue you should be concerned about is that packing your stuff correctly and effectively might be difficult, especially with the added bulk or additional layer of the pack liner.

If you don’t want to spend money on a pack liner, you may instead utilize huge plastic bags. You may also employ heavy-duty garbage bags that you can get almost anywhere. The overall look of the bag will also be enhanced by using a hat or other accessories. However, make sure you get a good seal around the bag’s neck. You may accomplish this by compressing the bag’s opening, folding it over the twist, then tying it in place with a good strong know or two.

You will need to be sure that the cover is either attached before you go out on your journey or if it’s a bigger backpack, add it when necessary so there won’t be any problems later on. If not, they may get damp from condensation inside of your pack, which would defeat its purpose altogether, making your belongings wet.

A rain cover is a good idea for any backpack, no matter its size or the conditions you’re heading into. You should be able to find one that fits perfectly with little trouble at all outdoor clothing shops and major department stores. If not, there are also cases where they may have covers of specific backpacks available.

However, don’t make the error of thinking a dry bag can be used in place of your regular backpack. Dry bags are only useful as a secondary backpack because they have just one major compartment.
