It is National Handbag Day today, and the fastest-rising bag searches this week are not about a new silhouette — they are about keeping one dry. The "handbag raincoat" idea keeps resurfacing for a reason: rain is the quickest way to age a bag. It darkens leather unevenly, leaves water rings, and on a woven surface it settles into the gaps between strips. Here is what actually works, material by material.
The short answer
Protect before, act fast after. Treat real leather with a pH-balanced waterproofing spray before the wet season starts. If a bag does get soaked, empty it, blot it (never rub), stuff it to hold its shape and let it air-dry upright at room temperature. Never use heat, and never leave a wet bag sealed inside plastic.
Why woven bags are a special case
A woven bag's surface is a lattice, not a sheet. Water does not just sit on top of it — it runs into the gaps between strips, and the cut edge of each strip is unfinished, so it takes on moisture faster than the face of the material does. That is why the rules below are mostly about keeping water out of the gaps, and letting it escape slowly if it does get in. Our full care guide covers cleaning; this article is about the wet-weather half.
What rain actually does, by material
| Material | In light rain | If it gets soaked |
|---|---|---|
| Woven cowhide (top-grain) | Rain darkens the surface and can leave water spots | Blot, stuff, air-dry upright 24–48 hours away from heat; condition only once fully dry |
| Woven PU (vegan leather) | Wipes clean; handles light rain best | Blot and air-dry; no conditioning needed |
| Microfiber lattice | Quick-drying; reshapes while damp | Blot, reshape by hand, air-dry |
| Straw / raffia-effect paper straw | Least rain-tolerant — dislikes soaking and can distort | Shake off, blot, dry flat and shaped; carry something else on wet days |
| Cotton crochet | Absorbs and sags when wet | Blot, dry flat away from sun; machine-wash only if the product page allows |
None of these materials is waterproof, and no woven bag should be described as such. PU is water-resistant — water beads on the surface — but it can still enter through stitching and an open top. For the longer explanation of what each material is, see our guide to the four woven bag materials and the cowhide guide on top-grain versus split.
How to protect a leather bag before the weather turns
- Use a waterproofing spray made for finished leather. Look for pH-balanced and alcohol-free formulas. Test it first on a hidden spot — the base of the bag or the underside of a strap — and let that dry fully before you judge it. Spray in a ventilated room or outdoors, apply thin even coats rather than one heavy one, and reapply once a season.
- Keep it off the ground. A bag that lives on a cafe floor or a train floor picks up the worst of the day's water and grit.
- Use the closure, and carry it close. A zip or magnetic top keeps the opening aligned and stops rain running straight into the bag on a wet commute.
- Consider a cover for the worst days. Purpose-made rain covers — the "handbag raincoat" format — and simple drawstring covers both do the same job. A foldable tote already in your bag works too. What does not work is wrapping the bag in a sealed plastic bag for hours, which holds humidity against the surface.
- Rotate. Give a damp bag a day off rather than carrying it wet again the next morning.
If your bag does get soaked: the 24-hour routine
- Empty it completely, open every zip, and remove a removable lining or pouch.
- Blot — do not rub — with a dry towel. Rubbing pushes water further into the weave.
- Stuff it loosely with acid-free tissue or a cotton pillowcase to hold the shape. Never newspaper, which transfers ink.
- Air-dry it upright at room temperature, away from radiators, hairdryers and direct sun. Leather needs 24–48 hours.
- Reshape while it is still very slightly damp if it has lost its form.
- Condition only once it is completely dry. Conditioning damp leather traps the moisture you are trying to remove.
Water stains and darkening
When water dries unevenly you get a ring or a darker patch. Let the whole bag dry completely first, then apply conditioner lightly and evenly — rubbing a damp spot only spreads it. Some people even out an old water ring by lightly damping the whole panel so it dries uniformly; if you try that, test on a hidden area first, and be ready to leave it alone, because most water marks fade with time and a light conditioning.
What not to do
- No heat. Hairdryers, radiators and hot cars dry leather too fast and crack the edges.
- No plastic bags. Sealing a damp bag traps humidity and encourages mildew.
- No alcohol wipes or bleach-based cleaners. They strip the finish, and on unfinished weave edges they cause permanent darkening.
- No over-spraying. Pooled waterproofing in the gaps collects dirt and can leave a cloudy film.
- No machine washing of anything woven, except cotton crochet on a product page that explicitly says the yarn blend allows it.
Choosing a rain-friendly woven bag
Short of a cover, material and closure do most of the work. A zip-top PU bag wipes clean and keeps the opening shut: the Box woven PU top-handle bag is 19 × 12 × 12 cm, closes with a zip and weighs 0.55 kg, and the Lune crescent is the same idea as a crossbody. A flap helps too — the Line baguette. In genuine leather, a zip is still the safer call, which is why the Mini Crescent cowhide bag is the one to reach for. Open tops and open weaves — a Market tote or an open-weave bucket bag — are the ones to leave at home when the forecast is bad.
FAQ
Can leather bags get wet?
They can survive it, but not without consequences. A short shower on finished leather is usually fine if you blot and dry it properly. Prolonged soaking is what causes uneven darkening, water rings, stiffness and weakened stitching — and a waterproofing spray lowers that risk considerably.
Is PU leather waterproof?
No. Woven PU resists water: rain beads on the surface and spills wipe away. But water can still get in through stitching and an open top, so treat it as water-resistant rather than waterproof, and dry the bag after a soaking.
Does a handbag raincoat actually work?
The cover idea works; the execution matters more than the brand. Anything that keeps rain off the surface and lets air circulate afterwards will help. What does not work is sealing a bag inside a plastic bag, which traps humidity against the material.
How do I dry a wet leather bag?
Empty it, blot it, stuff it loosely with tissue to keep its shape, and air-dry it upright at room temperature for 24–48 hours. Never use heat, and do not condition it until it is completely dry.
Will one rain shower ruin a woven straw bag?
Not necessarily, but straw and paper straw are the least rain-tolerant materials we sell — they dislike soaking and can distort. Shake off the water, blot it, and dry it flat in shape. On heavy-rain days, carry something else.
If you would rather not think about it, the practical split is simple: woven PU for wet weeks, woven cowhide for everything else — a spray on the leather once a season, and a zip on whatever you carry.
