There is an enemy that we often don't even notice in everyday life. It is odorless, colorless and harmless at first glance. But anyone who has ever spent a cold night in a tent with a soaking wet sleeping bag knows this: Water can be the biggest enemy of your equipment.
It's not the raging sea or the torrential river that can ruin your equipment, but a sudden downpour, an incorrectly packed rucksack or condensation in your tent. Electronics break, clothes get soggy, matches are unusable. A scenario that is annoying in everyday life, but extremely dangerous in an emergency situation.
But the good news is that with a few simple measures, almost everything can be packed in such a way that it stays dry - even when the rain is lashing down outside.
Why water protection is so important
Water is life, yes. But water is also a destroyer if it gets into the wrong places. Wet clothing cools the body down, soaked supplies go moldy, electronic devices are often dead after a few drops.
There is a saying in the prepper scene: „If you have two, you have one. If you have one, you have none.“ Applied to moisture, this means that if you don't have double protection against wetness, you risk being left empty-handed at the crucial moment.
Basic principles: How to keep equipment dry?
Before we go into details, a few guiding principles that always apply:
Protection in layers. One large waterproof bag is good, several small ones are better.
Redundancy. Secure important items twice - e.g. put electronics in a zip bag first, then in the backpack liner.
Adaptation to the application. A kayak tour requires different measures than a hike in the fall.
Regular inspection. Even the best cover is useless if it has holes.
Methods and materials at a glance
There are many ways to keep equipment dry. Some are simple, almost banal. Others require special material.
| Method | Advantage | Disadvantage | Suitable for |
|---|---|---|---|
| Zip bag | Very affordable, flexible | Limited shelf life | Small parts, electronics |
| Drybags (waterproof pack sacks) | robust, reliable | slightly more expensive, weigh more | Clothes, sleeping bag |
| Garbage bags/contractor bags | extremely affordable, versatile | tear more easily | Backpack liner |
| Waterproof boxes | Stable, also protect against impacts | heavier, bulky | Electronics, documents |
| Impregnation (sprays/wax) | Permanently water-repellent | Limited effect in continuous rain | Clothing, shoes |
Step by step: How to waterproof your equipment
1. secure the rucksack
The rucksack is the heart of the equipment - and the first place where water can get in. Rain covers are standard, but often not enough. Better: line the entire interior with a robust garbage bag or liner. All the pack sacks are stowed in this. This will keep the contents dry even if water seeps through every seam.
2. clothing and sleeping bag
Textiles are sensitive. In the worst case, a wet sleeping bag can be life-threatening. Therefore, always pack it in a separate drybag. Spare clothing should also be packed in waterproof bags - sorted by function (e.g. „warm“, „rain“, „sleep“). This way, you will know immediately where to go in an emergency.
3. electronics
Cell phones, GPS devices, power banks - all of these are sensitive helpers, but also Achilles' heels. Double-walled strategies help here: first in a zip bag, then in a waterproof box or drybag. If you want to be on the safe side, add small silica gel packets to absorb residual moisture.
4. documents and maps
Nothing is more annoying than a map that turns to mush when it rains. It's best to store them in transparent pockets or laminating pouches. For ID cards and papers, it's worth using special document pouches that are not only waterproof but also resistant to creasing.
5. supplies and fuel
Store food in plastic tins or zip bags. Matches in waterproof containers (e.g. empty film cans with a rubber seal). Tinder can be easily transported in small zip bags or tubes - it will only stay dry if you treat it like a treasure.
Two lists for practical use
Essential basics for water protection:
Zip bags in various sizes
2-3 drybags (different colors for order)
Robust bin liner as a backpack liner
Waterproof cover for cell phone
Rescue blanket as emergency wind and rain protection
Practical extras if you're serious:
Silica gel packs against residual moisture
Waterproofing spray for tents and clothing
Waterproof box (e.g. Tupper or Pelicase)
Replacement rain cover for the rucksack
Spare bin liners for flexible use
Mistakes to avoid
Only rely on the rain cover. It keeps water out, yes - but not against continuous rain or when the backpack is lying on wet ground.
All in one bag. If it falls into the water, everything is immediately wet. Better: several small fuses.
Use cheap materials for too long. Zip bags with holes are no longer waterproof helpers.
Underestimate moisture from inside. Condensation in the tent can be just as destructive as a rain shower.
A picture in your head
Waterproof protection is like a castle wall. Rain, fog, dirt - it all bounces off as long as the walls are watertight. But even a small crack is enough for moisture to seep in, unstoppably. That's why protection is not about perfection, but about layers, redundancy and regular checks.
Personal experience
I remember a tour in the fall when we were surprised by a sudden downpour in the mountains. Everything was soaked within minutes. Only the sleeping bag stayed dry - thanks to a drybag. The feeling of slipping into something dry at the end of the day was not just comfort, it was salvation. It was then that I realized: Waterproof protection is not a luxury, but a kind of insurance.
Conclusion: dryness is safety
It sounds banal, but it's essential: making your equipment waterproof not only ensures comfort, but also survival. Whether it's rain, snow or simply the moisture from your own breath in the tent - wetness is everywhere.
The good news: protection is not expensive, not complicated. A few bags, a bit of organization, a clear plan. You can turn your equipment into a fortress against the water.
And perhaps that's the best thing about it: the next rainy night loses its terror. Instead of fear of getting wet, there is the reassuring knowledge: Everything important stays dry.
