Drying Wet Camping Gear at the Campsite and on the Drive Home
Start with the clock: 24 hours to mildew
Wet gear does not need to be dry before the drive home. It needs to be on a schedule. MSR's tent-care guidance puts the deadline plainly: it can take as few as 24 hours for mildew to start forming on a wet, crumpled tent, and that mildew stains, smells, and compromises the waterproof coating. Behind mildew runs a slower damage track — prolonged exposure to moisture causes hydrolysis, the premature breakdown of the waterproof coating, which leaves it soft, sticky, and no longer waterproof.
That clock turns a vague chore into three phases with a deadline. At the campsite, get water out of the gear and off its surfaces. On the drive, keep the wet gear from soaking the dry gear and let the vehicle do what drying it can. On arrival, finish the job the same day. A wet tent packed for the drive is not a failure — Cascadia Vehicle Tents tells its owners that packing a tent or awning away wet to travel home will not damage it, provided the wet gear is addressed as soon as possible at home or the next destination. The failure is the wet bundle forgotten in the car for three days.
At the campsite: triage by gear, not by order of packing
Pack-up usually runs in the order things are reached. Drying runs in a different order — insulation and sleep items first, because a damp sleeping system is the item that can least afford to stay wet, and wet gear gets isolated so it stops soaking dry items. Work the kit in this order:
| Gear | Campsite move | Why this method |
|---|---|---|
| Sleeping bag and insulation | Keep it in its waterproof protection until the tent comes down; if damp, air it unzipped in any dry window and pack it loose, never compressed while wet | Wet down must never be compressed, and a sleeping bag's loft is what traps body heat — compression damages it; synthetic insulation tolerates damp better, retaining heat even when wet |
| Socks and next-day clothing | Wring thoroughly, then roll tightly in a microfibre towel to pull out excess water; hang in the tent only if lightly damp, with ventilation wide open | The towel roll removes water wringing alone leaves; soaking-wet items hung inside a tent raise condensation instead of drying |
| Boots | Pull the insoles out to dry separately; stuff the boots with spare dry material and swap the stuffing every few hours | Insoles hold moisture against the boot's interior; no direct heat — fires and radiators can crack leather and melt adhesives |
| Tent and fly | Shake off, wipe down, and leave pitched or hung as long as the schedule allows; pack it last | Every extra minute pitched is water leaving the fabric before the 24-hour clock starts in earnest |
One prohibition covers the whole table: do not use a camp stove to dry gear. Flames and synthetic fabrics do not mix, and the same caution applies to propping boots at the fire's edge — the heat that dries fastest is the heat that damages adhesives and leather.
When the air will not take water: the contain-and-drive decision
Some pack-ups happen in air that cannot accept more moisture. Campers discussing exactly this problem note that in wet weather at 100% relative humidity, nothing outside will dry, even under an awning. Hanging gear out in saturated air is not patience; it is the mildew clock running while nothing improves.
The decision rule is simple. If surfaces are still gaining condensation as fast as they lose it — if the towel comes away as wet after an hour as it did at the start — stop drying and switch to containment: wring everything once more, isolate the wet gear in its own bag or bin, and drive. Contained wet gear with a same-day appointment at home beats gear hung hopefully in wet air for an extra three hours. What containment must never become is storage: damp gear sealed in a bag traps moisture, which is a transport arrangement for hours, not a place for gear to live.
The drive home: wet zone, dry zone, moving air
- Pack the dry gear first, while it is still sheltered. Sleeping gear and dry clothing go into the vehicle sealed before the wet shelter comes down around them.
- Strip the tent in the right order. Take all sleeping gear out of the tent first, then close the tent's windows and doors before folding it away — the closure keeps outside wet and dirt from being folded into the interior.
- Build a wet zone in the cargo area. One camper's working arrangement, reported from the road: a large towel spread over the plastic storage boxes in the back of the vehicle, with the wet things laid on it. The towel takes the water, the boxes take the weight, and the wet load stays in one defined area instead of migrating across the cargo floor.
- Let the vehicle's climate system work. The same road report found that running the heater and/or air conditioning while travelling does a good drying job on gear laid out in the wet zone. Lay items in a single layer where the space allows; a heaped pile dries only on its outside.
- Keep the zones apart at every stop. Nothing dry goes on top of the wet zone, and the wet bag is never opened to add a dry item found late. Found-late dry items ride in the cabin instead.
Success check on arrival: the dry gear comes out of the vehicle dry — not mostly dry, dry — and every wet item is in one place, ready to move straight to its drying position without a sorting session on the driveway.
On arrival: finish the job the same day
- Unpack the wet zone first, before the dry gear is put away. The mildew clock does not pause for unpacking the rest of the car.
- Pitch or hang the tent in a dry place with good air flow. A dry environment with airflow is what dries a tent or awning efficiently; a tent that cannot be opened where it sits may need to come off the vehicle or out of its bag and be draped or hung instead. Never machine-dry a tent; if it needs washing, hand wash with warm water, a sponge, and mild non-detergent soap, then dry it fully pitched or hung.
- Finish the sleeping bag loose. Unzip it and hang it — the manufacturer's guidance is to hang a bag for 24 hours to dry — and store it uncompressed, in a large bag that does not squeeze it or hung by its loop.
- Finish the boots at room temperature. Insoles out and drying separately, boots at normal temperature in low humidity, newspaper stuffing changed whenever it becomes damp, or a fan turned on them. No radiator, no fireplace, no heater — high heat weakens adhesives and ages leather early. Boots are then stored somewhere ventilated, not back in a damp or hot trunk.
- Store the tent loose and breathable. In an oversized breathable cotton bag or mesh duffel rather than its stuff sack, in a cool, dry place out of direct sunlight.
What success looks like before anything goes into storage
Run this check item by item before any piece is put away. The tent's panels, seams, and corners are dry to the touch with no cool patches, and there is no musty smell when a section is held folded for a moment. The sleeping bag is fully lofted, dry through its insulation, and stored uncompressed. Boots are dry inside at the toe, with the insoles dry and back in. Clothing has no damp fold left in it. Anything that fails its check stays out in moving air for another round — storage is only for gear that has passed, because the 24-hour clock that started at the campsite keeps running in the cupboard for anything put away damp.
