TERMS GUIDE FOR TRAIL RUNNING WATERPROOF JACKETS
Membranes: Protecting Against Rain While Staying Breathable
Waterproof membranes, such as GORE-TEX and eVent, are vital for staying dry while trail running, but they offer more than just rain protection. These advanced membranes feature microscopic pores that prevent water droplets from penetrating, allowing sweat vapour to escape. This breathability is essential during trail running, where high-intensity activity generates heat and moisture. Without a breathable jacket, sweat would build up inside, leaving you damp, uncomfortable, and at risk of overheating or chilling when you pause or slow down. A quality waterproof jacket ensures you stay dry and comfortable, even during challenging runs in unpredictable weather.
Two-layer and three-layer membranes
You’ll often see terms like two-layer and three-layer membranes regarding trail running jackets. A two-layer jacket typically has a waterproof membrane bonded to the outer fabric with a loose lining inside, offering a balance of waterproofing and comfort. These jackets are lightweight and ideal for shorter runs or moderate conditions.
On the other hand, a three-layer jacket incorporates an additional protective layer, making it more durable and breathable—perfect for intense, longer trail runs in challenging weather. While three-layer jackets are often pricier, they’re a worthwhile investment for runners tackling demanding trails or racing in unpredictable conditions where top performance is key.
Hydrostatic Head: Understanding Waterproof Ratings for TRAIL RUNNERS
The hydrostatic head rating measures how waterproof a trail running jacket is by assessing the amount of water pressure it can resist before leaking, expressed in millimetres (mm). For instance, a jacket with a 10,000 mm rating can withstand a 10,000 mm column of water before water seeps through. The higher the number, the more waterproof the jacket.
For most trail running conditions, a jacket rated between 10,000 mm and 15,000 mm protects against moderate rain or light showers. If you’re running in areas prone to heavy rain or extreme weather, such as mountainous regions, consider a jacket with a rating of 20,000 mm or higher to ensure reliable performance and keep you dry on the move.
RET (Breathability Rating): Managing Moisture on the Trail
RET, or Resistance to Evaporative Heat Transfer, measures how effectively a trail running jacket allows moisture (like sweat) to escape. The lower the RET number, the more breathable the jacket. Ratings between 0 and 6 indicate excellent breathability, ideal for high-intensity activities like trail running, while 7 to 12 is suitable for most runs. Jackets with a RET above 20 are less breathable and better suited for low-intensity activities.
Breathability is crucial for trail running due to the heat and moisture your body generates during intense effort. If your jacket lacks sufficient breathability, sweat can build up inside, leaving you damp and uncomfortable. This can cause you to overheat while running or feel chilled during breaks, especially in cooler weather. Opting for a low RET rating jacket ensures you stay dry and comfortable, even during demanding runs on warm or humid trails.
Packability: Keeping Weight Down for TRAIL RUNNERS
When you’re trail running, every gram matters. A lightweight, packable, waterproof jacket is essential because it can be stashed in your running vest or belt without adding bulk or weight. Packability is key since weather can change quickly on the trail, and having an easy-to-carry jacket ensures you’re always ready for sudden rain or wind.
However, there’s often a trade-off between weight and durability. Ultralight jackets are great for speed and packability but may sacrifice some durability compared to heavier options. Depending on your trail running needs, you might prioritise an ultralight jacket for races or long runs or choose a slightly heavier and more durable jacket for rugged trails or harsher weather conditions.
Generally, a trail-running waterproof jacket should ideally weigh between 100 and 250 grams (3.5 to 9 ounces). Aim for the lower end of this range for competitive runners or those covering long distances. For tougher trails or more durable options, weights up to 300 grams (around 10.5 ounces) are manageable without compromising packability.
PFC-Free DWR: Water Repellency
Most trail-running waterproof jackets feature a DWR (Durable Water Repellent) coating that allows rainwater to bead up and roll off the surface, preventing the fabric from becoming saturated. This outer layer is critical for keeping the jacket lightweight and breathable during wet runs. Traditionally, DWR coatings included PFCs (perfluorinated compounds), which harm the environment. Fortunately, many brands now use PFC-free DWR, which offers the same performance with a lower environmental impact.
For trail runners, this eco-conscious shift means you can choose a jacket that aligns with your values without compromising performance. Remember that DWR coatings can wear off over time, especially with regular use or washing. Reapplying a DWR treatment with a suitable product is simple. It ensures your jacket performs at its best, keeping you dry and comfortable on every trail, no matter the weather.
FEATURES TO LOOK FOR IN A TRAIL RUNNING WATERPROOF JACKET
Lightweight Design
When you’re trail running, every gram counts. A lightweight jacket ensures you can carry it easily without adding unnecessary bulk. Look for jackets weighing 100 and 250 grams, balancing protection and packability.
Packability
A packable jacket is a must for trail running. Choose one that compresses into its pocket or a small stuff sack, making it easy to stow in your running vest or belt. This feature is invaluable for dealing with sudden weather changes on the trail.
Articulated Fit
Freedom of movement is key on the trails. Jackets with articulated sleeves, gusseted underarms, or a slim, athletic fit are ideal for running. They allow you to move naturally without excess fabric flapping or restricting motion.
Ventilation Features
For intense runs, extra ventilation is a game-changer. Look for jackets with underarm zips, mesh-lined pockets, or strategically placed vents to boost airflow without sacrificing waterproofing.
Reflective Details
Safety is critical, especially in low-light conditions. Jackets with reflective accents or logos improve visibility during early morning or late evening runs, ensuring you’re seen on trails or roads.
Pockets for Essentials
Trail runners need easy-access storage for small essentials like gels, keys, or a phone. Look for jackets with water-resistant chest or side pockets positioned to avoid interference with a running vest or pack.
Hem and Cuff Adjustments
An adjustable hem helps seal out wind and rain, while elastic or Velcro cuffs keep sleeves snug around your wrists. These features ensure a secure fit, even during fast-paced movement, and stop rain from sneaking in.
Waterproof Zippers and Seam Sealing
To stay truly dry, ensure the jacket features waterproof zippers and fully taped seams. These details prevent water from seeping in through vulnerable areas, keeping you comfortable in heavy rain.
How to Care for a Waterproof Jacket For TRAIL RUNNING:
Washing and Reapplying DWR
Proper care for your waterproof jacket is essential to maintaining its performance, extending its lifespan, and ensuring it stays effective against the elements. Here’s a guide on why this is important and how to do it right.
Why You Need to Wash and Reapply DWR
Modern waterproof jackets rely on two key components: a waterproof membrane (such as Gore-Tex®) and a Durable Water Repellent (DWR) coating on the outer fabric. Over time, the DWR layer can wear off due to friction, dirt, and oils, leading to a phenomenon called “wetting out.”
When a jacket wets out:
- Water no longer beads off the surface and instead soaks into the fabric.
- While the waterproof membrane prevents water from penetrating, the soaked fabric can feel heavy, and moisture from sweat or condensation
may accumulate inside, reducing comfort. - This is often mistaken for a faulty jacket, but it needs proper cleaning and re-treatment.
By washing your jacket and reapplying DWR, you reactivate its water-shedding capabilities, ensuring it performs as intended. Regular care is particularly important for modern waterproofs using PFC/PFAS-free DWR, as these environmentally-conscious formulas may require more frequent maintenance.
How to Wash and Reapply DWR
- Prepare Your Jacket
- Empty all pockets and fasten zips, Velcro, and flaps to prevent damage during washing.
- Check the care label for any specific instructions.
- Wash with a Technical Cleaner
- Use a specialised tech wash (avoid standard detergents, as they can leave a residue that reduces performance).
- Wash on a gentle cycle with cool water, as per the care label.
- Dry Your Jacket
- After washing, tumble dry on low heat if the care label permits. The heat helps reactivate the DWR to some extent. If tumble drying isn’t recommended, air dry thoroughly.
- After washing, tumble dry on low heat if the care label permits. The heat helps reactivate the DWR to some extent. If tumble drying isn’t recommended, air dry thoroughly.
- Reapply DWR
- Use a spray-on or wash-in DWR treatment, following the product instructions.
- For spray-on products, focus on high-wear areas like shoulders, cuffs, and the hood.
- Once applied, use low heat in a tumble dryer or iron in a warm setting (with a cloth between the iron and jacket) to set the treatment.
Why Early and Regular Care Matters
We recommend washing and reapplying DWR to any new waterproof jacket right from the start. This habit ensures the fabric is clean and the water-repellent finish is at its best, helping you achieve peak performance from day one. Periodic maintenance prevents wetting out, improves comfort, and prolongs the life of your jacket.
Caring for your jacket also supports responsible outdoor practices by reducing the need for replacements and ensuring your gear remains eco-conscious.
