Waterproof Ratings and Breathability Explained
A golfer’s guide to the Tindall 2.0 System
Understanding golf waterproof ratings helps you choose rain gear for passing showers, steady rain and long rounds in inclement weather. This guide explains waterproof and breathability ratings, compares 5K through 20K performance levels, and shows where the Tindall 2.0 System (20k/30k) fits.
What is a waterproof rating?
A waterproof rating measures how much water pressure a fabric can withstand before water begins to penetrate. It is expressed in millimeters, often shortened to “K” for thousands.
In a laboratory test, fabric is exposed to increasing water pressure. A 20,000mm—or 20K—rating represents resistance to pressure equivalent to a 20-meter column of water.
A higher number generally means greater resistance to water pressure. It does not measure rainfall amounts or guarantee a specific number of dry hours on the course.
Waterproof ratings at a glance
| Waterproof rating | General protection | What it means for golf |
|---|---|---|
| 5,000mm / 5K | Basic | Light showers and brief exposure. |
| 10,000mm / 10K | Moderate | Intermittent rain and changeable conditions. |
| 15,000mm / 15K | Good | Steadier rain and longer periods outdoors. |
| 20,000mm / 20K | High | Heavy rain and prolonged exposure during wet rounds. |
These ranges are general guides. A garment’s seams, zippers, openings and condition also affect how well it protects you.
Why construction matters
Waterproof fabric is only part of the equation. Rain can find its way through unsealed stitching or poorly secured openings, regardless of the fabric’s rating.
The Tindall 2.0 Jacket combines 20K waterproof protection with a three-layer waterproof laminate, fully sealed seams and a waterproof front zipper. Adjustable cuffs and a drawcord hem help secure the fit, while a drop-tail hem adds coverage.
Together, these details support protection when a passing shower settles in for the round.
What is breathability?
Walking fairways, climbing hills and carrying clubs generate heat and perspiration—even when it’s cool outside. If that moisture builds up inside your clothing, you can feel damp without rain ever getting through.
Breathability describes how readily moisture vapor passes through fabric. It is commonly measured as Moisture Vapor Transmission Rate, or MVTR, expressed in grams per square meter over 24 hours: g/m²/24h.
Higher numbers indicate greater moisture vapor transfer when tested using the same method. Unlike waterproof ratings, breathability ratings are not measured in millimeters.
Breathability ratings at a glance
| Breathability rating | General level | What it means for golf |
|---|---|---|
| 5,000g/m²/24h / 5K | Basic | Lower activity levels and rounds with limited walking. |
| 10,000g/m²/24h / 10K | Moderate | Comfortable-paced walking and everyday play. |
| 15,000g/m²/24h / 15K | Good | More active walking and rolling terrain. |
| 20,000g/m²/24h / 20K | Very good | Brisk walking, carrying clubs and hillier courses. |
These are broad guidelines. Humidity, temperature, pace, fit and the layers underneath all influence how breathable a garment feels. No breathable shell can guarantee that you will never perspire or feel damp.
Where Tindall 2.0 fits
The Tindall 2.0 Jacket pairs 20,000mm waterproof protection with 30,000g/m²/24h breathability—or 20K / 30K.
The first number describes resistance to water pressure. The second describes moisture vapor transfer, exceeding the breathability range shown in the chart above.
For golfers, that combination addresses both sides of wet-weather comfort: protection from rain outside and moisture management inside. Soft, flexible construction and articulated sleeves support natural movement from address through follow-through.
Paired with the Tindall Rain Pant, the jacket forms the Tindall 2.0 System for wet-weather rounds.
Waterproof, water-resistant and water-repellent
These terms describe different types of protection.
| Term | What it means |
|---|---|
| Water-resistant | Resists some moisture, but may allow water through during sustained or heavy rain. |
| Water-repellent | Encourages droplets to bead and roll off the outer surface. This finish alone does not make a garment waterproof. |
| Waterproof | Uses a protective fabric, coating or membrane to resist water penetration. Overall protection also depends on garment construction. |
Beading is useful, but it does not tell the whole story. A water-repellent surface and a waterproof barrier perform different jobs.
Dress for the full round
Your layers should match both the forecast and how you play.
- Mild and rainy: Keep underlying layers light to manage warmth while walking.
- Cold, wet and windy: Add an insulating layer beneath your shell, leaving enough room for a comfortable swing.
- Showers moving through: Keep waterproofs accessible and put them on before your clothing becomes soaked.
- Persistent rain: Wear jacket and rain pants together, and secure cuffs, hems and closures.
Try your layers together before heading out. You should be able to rotate, reach and swing comfortably without fabric pulling across your shoulders.
Keep your rain gear ready
Regular care helps maintain performance. Dirt, body oils and wear can affect the outer fabric’s ability to repel water. If the surface becomes saturated, it may feel cold or clammy even while the waterproof barrier continues working.
Follow the garment’s care label for washing, drying and any recommended treatment. Let your rain gear dry fully before storing it, and check periodically for damage around seams and closures.
