Dry Bag

A roll-top dry bag keeps spare clothes, electronics and food genuinely dry when a rucksack or boot can't — the difference between a warm night and a wretched one.

Dry Bag

Why it matters

Wet kit is more than an annoyance — a soaked sleeping bag or spare layers can turn a cold night dangerous, and damp electronics or matches simply stop working. A dry bag is a waterproof barrier you pack the important things inside, so a downpour, a river crossing or a leaking boot doesn't ruin what keeps you safe.

Because it rolls flat when empty and comes in sizes from a few litres up, it earns its place in almost any kit. It also doubles as a way to keep dirty or wet gear away from clean, and a large one can even carry water in a pinch.

When to use it

Use it to protect anything that must stay dry — spare clothing, a sleeping bag, first-aid supplies, phone, matches and food — during wet-weather hikes, kayaking, camping or car travel. Line the inside of a rucksack with one and your whole pack becomes effectively waterproof.

Features to look for

A roll-top closure

A proper roll-top rolled three or more times and clipped is what makes the seal waterproof. Zips alone rarely keep out sustained rain or submersion.

Welded, not stitched, seams

Heat-welded seams stay watertight; stitched seams let water wick through the needle holes over time.

The right size and a strap

Pick a size for the job — 5–10L for essentials, 20L+ to line a pack — and a shoulder strap or lash points make it easier to carry or secure.

Common mistakes

Under-rolling the top

One fold isn't enough. Roll the closure down firmly at least three times before clipping, or water will find its way in.

Overstuffing it

Cram it full and you can't roll the top properly, breaking the seal. Leave enough slack at the opening to roll and clip cleanly.
