Nothing is worse than opening your pack to find soaked clothes and wet equipment during a hiking trip or any other adventure. That is why pack covers and pack liners are necessary when preparing to go for any excursion.
A pack liner will keep the contents of the pack dry, but not the pack itself or any goods kept in outer pouches. A pack cover will also not totally keep water out. However, a pack cover will keep the majority of the water out of the pack while also keeping the items in the outside pockets dry.
Pack covers and liners are most efficient when combined together. This way both the interior contents of your bag and the exterior of your bag will be protected from the rain. In this article, we will focus on the differences between the two and when to use them.
Pack liner vs pack cover – Key differences
Pack liners and pack covers are mostly used hand in hand. It all depends on the backpacker’s preferences and how much knowledge they have on gear protection. The table below shows key differences between pack liners and pack covers.
|Pack liners||Pack covers|
|They keep your internal gear dry, but your pack becomes wet.||They keep your packs dry, but your inside stuff becomes wet.|
|They are heavier||They are very light compared to liners|
|They are available at affordable prices||They are quite pricey|
|They protect gear that is already inside your backpack so everything else from the bag straps to the rear of your bag becomes wet||They protect external pockets, which carry my often utilized accessories.|
|Only protect the inner part of your backpack. Ensures stuff like food, and sleep clothes do not get wet.||Guard the pack against harsh terrain, mud, brush, pebbles, and so on.|
|Their only purpose is to prevent wetness||Can be used to rinse dirty undergarments as a privacy kilt and also as a temporary sink basin.|
The most obvious reason for using a pack cover is to keep your backpack and its contents dry. Food, electronics, clothing, a jacket, and a sleeping bag must all be kept dry to maintain their functionality.
Secondly, a pack cover provides an extra layer of protection for your bag, preventing tears and abrasions. Some backpacks are made of flimsier materials, and an accidental brush against a jagged rock, spiky stick, or thorn can pierce them.
Another reason to use a pack cover is that it can make you more noticeable if it is brightly colored. This is especially vital during hunting season to avoid being mistaken for prey.
Being more visible can also help others discover you in the event of an accident, as a brightly colored rain cover will be simpler to identify during a search and rescue. For these reasons, certain rain covers are made of bright and reflective materials.
They also protect anything attached to the outside of your backpack or within external pockets from getting wet.
Pack covers are particularly lightweight. They are less than 2 ounces in weight. Unless you count every ounce, the advantages of a pack cover outweigh the increased weight.
The downside is they add weight to the backpack and this may be quite disadvantageous to someone trying to achieve base weight.
Some pack covers have seams that run along the main body. These seams are factory sealed, however, the sealant will ultimately wear away. Water may leak into your bag as a result of this. You can, however, re-seal the seams yourself or purchase a new pack cover.
The rear part of your backpack (what presses against your back) is not, or is only partially, protected by a pack cover. This does provide a vulnerable location for water to enter your backpack, but with a few extra precautions (such as a waterproof pack liner), your contents should remain dry.
However, your shoulder straps and hip belt are entirely exposed, so if you’re storing anything in the shoulder or hip belt pockets, make sure they’re safe by storing them in sealable storage bags.

When to use a pack liner
Consider utilizing a pack liner while going on a long hike. They are less prone to tears, and if they do occur, they may be repaired with duct tape.
Volume is one of the characteristics that distinguish and adds value to a waterproof pack liner. It can fit everything in your other stuff sacks and more. It is usually large enough in an emergency to provide shelter or basic clothing.
There is no way to compensate for it in your backpack with other stuff sacks or equipment because nothing else comes close to matching its versatility.
