Keep your Pump Sack 20L inflating fast with a simple care routine. Learn how to clean, dry, store, and spot-repair the roll-top pump so it stays ready for every trip.

Quick answer

Rinse the Pump Sack 20L with plain water after trips, dry it fully inside and out before storing it loosely, and check the roll-top closure and seams for wear. That routine keeps the pump easy to roll and protects your sleeping pad from trapped moisture.

Why the roll-top design changes how you clean it

The Pump Sack 20L is a roll-top pump, not a sealed stuff sack. Air enters through the open top, and you roll the sack toward the valve to push air into the pad. That means the inside collects condensation and grit over time, and the roll-top edge takes repeated folding stress. Clean the inside, not just the outside, and pay attention to the closure area where creases form.

What to avoid when cleaning and storing

Skip harsh detergents, bleach, and machine washing. They can degrade the lightweight fabric and coatings that make the sack packable. Also avoid storing the sack compressed in a tight bundle for months; permanent creases along the roll-top can weaken the seal and make the pump harder to roll smoothly.

Step-by-step Pump Sack 20L care

Rinse after each trip: Turn the sack inside out and rinse with plain lukewarm water. Do not use soap or detergent unless the manufacturer approves it. Common mistake: washing only the outside and leaving condensation and grit inside. Rinse the inside, not just the shell.
Dry completely before storage: Hang the sack open in a shaded, ventilated spot until the inside and outside are fully dry. Avoid direct sunlight for long periods. Common mistake: rolling it up damp, which traps moisture and can lead to mildew. If you feel any dampness, keep drying.
Check the roll-top and seams: Inspect the roll-top edge and seams for small tears, pinholes, or delamination. Run your fingers along the folds to feel for weak spots. Common mistake: skipping this check until the pump fails on a trip. A quick feel for rough spots catches most wear early.
Store loosely, not compressed: Keep the sack in a loose bundle or hang it in a gear bin. Do not store it compressed under heavy items. Common mistake: cramming it into a tight stuff sack for months, which sets creases along the roll-top. Loose storage protects the roll-top fold lines.
Repair small issues promptly: For pinholes or small tears, use a patch or repair tape suitable for lightweight fabrics. Clean and dry the area first. If the roll-top closure is torn or delaminating, contact the manufacturer for guidance rather than relying on a field fix. Common mistake: patching over dirt or moisture, which prevents the repair from bonding. Clean and dry before any patch; structural damage needs professional help.

Product facts

Pump Sack 20L: The Pump Sack 20L is a roll-top pump that snaps to your pad's valve and inflates it by rolling air toward the valve. Because the sack pushes air directly into the pad, keeping the inside clean and dry helps prevent condensation and debris from reaching your sleeping pad.
