Collapsible Water Bladder 10L

10 liters of drinking water stored flat in a corner. Expands only when you fill it.

When it matters

• Home water main rupture or contamination: municipal advisory means taps are dry or unsafe. Bladder stores boiled water from reserves or collected rainwater.
• Evacuation with transport: fill it at last safe source (friend's well, gas station fountain), fold it into pack, carry 10 liters to new shelter.
• Shelter-in-place with rationing: gravity system needs a raised container; bladder hangs from rafter, feeds downward through filter.

What it does

• Bulk water storage when mains fail (boil first, store safely)
• Transport from distant source to basecamp shelter
• Paired with gravity filter as top-feed container
• Non-obvious: emergency shower or wound rinse (small cap allows controlled pour)

Built to last

Food-grade plastic but NOT a long-term storage vessel (UV and oxygen migration). Rotate water every 6 months. Seams are weak if dropped full; handle carefully.

Where it fits your kit

Home 72-Hour layer. AquaStraw Field Filter: Straw pre-filters drawn water before bladder storage; or bladder feeds emergency drinking if treated separately. Gravity-Feed Water System: Bladder hangs as top chamber; system processes downward through filter into collection container.

Specs

• Capacity: 10 liters
• Materials: Food-grade polyethylene
• In the box: 1x bladder

Field notes

• Before first use, rinse thoroughly—new plastic has manufacturing oils. Fill/drain 2–3 times with clean water.
• When hanging for gravity filter, support the seams with rope harness, not just the top cap. Seams fail under full-weight stress.
• Mark fill level with tape on the side so you can ration (e.g., 5L morning, 5L evening).

FAQ

Q: How long can I store water in this? Up to 6 months if kept cool, dark, and sealed. Plastic degrades in sunlight. Replace water seasonally.

Q: Can I put hot water in it? Not immediately after filling with cold. Rapid temperature change can warp seams. Fill with warm to moderate-temp water only.

Q: Will it puncture easily? It's durable for normal use, but sharp objects and drops will damage it. Don't overfill (pressure ruptures seams).
