Why a pack liner still matters
Updated October 5, 2026
Pack the liner
Put it inside the main compartment around the quilt and clothes. A cover alone channels water into the back panel on some packs.
Heavy rain
In a storm, the shell you are wearing is not the shell your bag is wearing. Stop and check the liner before the pass, not after the bag is wet.

Waterproof roll-top
Hyperlite Mountain Gear Southwest
The Southwest is a roll-top DCF pack for hikers who already pack like they own one. There is no trampoline back and not much forgiveness if the load is heavy or sloppy. Rain stays out better than it does in a standard nylon pack, which is the reason to pay for it. If you want lid pockets and organization, the Osprey Atmos AG 65 or the Gregory Baltoro 65 will annoy you less. If you want a lighter framed pack while you are still learning what to leave at home, the Gossamer Gear Mariposa still has a hip belt and a less harsh carry. The Southwest isn't sold on Amazon US, so there is no buy button for it here. We don't swap in a different pack.
Who should buy it. Experienced hikers in wet country whose kit is already simple enough for a roll-top.
Pros
- Highly water resistant
- Light for the fabric
- Simple roll-top
Cons
- Expensive
- Uncomfortable when overloaded
- Few pockets

Best cheap organization
10-liter dry bag
Most backpacks are water resistant, not waterproof. Rain plus a stuffed lid is how down gets wet. A cheap dry bag around the bag or quilt is the fix. Test the roll at home. No-name seams vary, so do not trust one with a phone you cannot replace.
Who should buy it. Every backpacker.
Pros
- Protects the bag
- Cheap
- Doubles as a stuff sack
Cons
- Seam quality varies
- User error on the roll

FAQ
Is a DCF pack enough?
It is better. A river crossing can still fill it. A liner is cheap.
Where do wet clothes go?
Outside the liner, in a separate bag.
