Tent Waterproof Ratings, Materials & Why You Shouldn’t Spray Your Redverz

Tent Waterproof Ratings, Materials & Why You Shouldn’t Spray Your Redverz

When it rains, it pours — especially lately.

At rallies, on the road, and in customer inboxes, one question keeps popping up:

“What should I spray on my Redverz tent to keep it waterproof?”

The short answer? Nothing. Don’t spray it. Please.

Redverz tents are engineered to handle real storms — straight out of the bag. In this guide, we’ll break down what waterproof ratings actually mean, how Redverz stacks up against the rest, and why applying aftermarket sprays is not just unnecessary, but potentially damaging.

Hydrostatic Head: What It Really Measures

When we talk about waterproof ratings, we’re talking hydrostatic head — a measurement (in millimeters) of how much water pressure a fabric can withstand before it starts to leak.

A column of water is placed over the fabric. The height at which water begins to seep through determines its hydrostatic head rating.

Here’s a general guide:

Rating (mm)	Description
0–1,000 mm	Water-resistant. Good for mild conditions.
1,000–1,500 mm	Basic waterproofing. Typical 2–3 season tents.
1,500–2,500 mm	Resists rain, but may not last in a true storm.
2,500-3500 mm	High waterproofing. Handles heavy rain well.
4,000 mm+	Storm-ready. For serious downpours and exposure.

Where Redverz Stands

We don’t flirt with the minimums:

• Outer Flysheet: 4,000mm hydrostatic head

• Tent Floor: 10,000mm hydrostatic head

This goes far beyond “standard waterproofing.” These materials are built for real-world conditions — including flash floods, wind-driven rain, and the kind of weather we saw recently at the Lebanon Rally, where Redverz riders stayed dry even as the fairgrounds turned into a mud pit.

We use high-grade polyester with premium PU (polyurethane) coatings — engineered to last and perform without extra treatment. The result is a tent you can trust in any conditions.

Why Spraying a Redverz Tent is a Bad Idea

We get it. You want to protect your gear.

But Redverz tents are already fully waterproof. Spraying aftermarket coatings can actually:

• Damage factory-applied coatings like silicone, breaking down the surface.

• Void performance, are tents are pre treated with a beading agent, these sprays often damage this.

In short: don’t spray your Redverz. You’ll do more harm than good.

Tent Waterproofing Isn’t Just About Numbers

Waterproof ratings are a great benchmark — but they don’t tell the whole story. Here’s what else matters:

• Construction Quality

  Taped seams, strategic stitching, and smart panel layouts all contribute to weather resistance.

• Floor Strength

  Our 10,000mm floors handle pooling water and high foot traffic without giving in.

• Ventilation

  Keeping water out is great. But if your tent can’t breathe, you’ll wake up in a damp fog.

• Site Choice

  Even the best gear won’t save you if you pitch in a runoff path. Elevation and drainage matter.

Redverz: Built for the New Normal

Let’s face it: weather is changing. Fast.

Storms are more intense. Rain is heavier. Dry spells are fewer and farther between. Lightweight summer tents with 1,500mm flysheets aren’t built for this.

Redverz tents are.

They’re engineered to be storm-ready, right out of the stuff sack — no aftermarket tweaks required. It’s the kind of reliability riders trust from Alaska to Patagonia.

“It was by far the most comfortable, most reliable tent we have ever used.” — Bozo on a Bike Read the full review

Redverz: Designed to Withstand. Built to Last.

We’ll keep saying it because it keeps proving true:

When you’re out in the wild, your tent is your house.

It has to work. Always.

Whether you’re pushing through downpours on a rally or camped out in remote terrain under unpredictable skies, Redverz tents are trusted to keep riders dry, safe, and comfortable.

So if you’re wondering whether you need to spray it — don’t.

Your tent is already ready.
