How To Re-Waterproof Your Ski Jacket

Updated: Jun 6, 2019

Over time, ski jackets can lose their water-repellency.

Waterproofing doesn’t last forever.

Whether from rubbing against a dirty car while straining to reach the ski rack, or spilled apres-drinks, a dirty jacket will stop repelling water. Luckily, it’s easy to clean and re-waterproof your ski jacket so you can get back to schralping pow.

The trick is to clean your jacket first.

Most times, it’s dirt and crud that are covering the water-repellent coating, making your jacket soak up water.

Quick tip: If you have stubborn stains, pour a little Tech Wash on them and scrub with a soft-bristled brush before washing.

Here’s how to clean.

  1. Place jacket(s) in washing machine. If you only have one jacket, maybe ask a friend if they want a clean jacket too. They can owe you.

  2. Add Nikwax Tech Wash. In a top-loading machine, add three full caps (150ml) for 1-3 garments or five full caps (250ml) for 4-6 garments. In a front loader, it’s best to add no more than two garments with two capfuls (100ml) of Tech Wash. Special note: If you live in an area with hard water, toss in an extra capful of Tech Wash. If you have an HE machine, use about half the recommended amount so you don’t suds up the place.

  3. Sit back with a good book and a glass of wine/beer/hot cocoa as the machine runs its course.

  4. More often than not, this single cycle will be enough to have revitalized your jacket.

A clean jacket is better at repelling water (and snow)!

But my ski jacket still isn’t waterproof!

That’s ok. Don’t panic. Over time the water-repellent finish can wear off. When that happens, it’s time to add more waterproofing.

Here’s how to waterproof.

  1. Clean first. Always clean first. Use Tech Wash like before. Then…

  2. If you have a top-loading machine, let the machine fill, then add a maximum of 3 garments and 300ml of TX. Direct Wash-In. Run a heavy/warm cycle.

  3. If you have a front-loading machine, add a maximum of 2 garments and 200ml of TX. Direct.

  4. Follow the manufacturer’s instructions as to whether your garment should be line or tumble dried. Nikwax does not require heat for activation, so you’re good to go either way.

  5. Put your jacket on and admire your waterproofed duds in the mirror.

There you have it!

Now you’re ready to hit the slopes again and laugh at the soggy fools clustered around the fire pit.

Or, maybe you can tell them about taking care of their ski jackets and spread the dryness.
