Performance Tested by Ultra Runners
“When you start to heat up, you need to manage that yourself. You can do this by allowing air into the jacket by opening the zip and using the ventilation popper or taking off layers (think hats and gloves which can easily be removed and slipped into the pockets of the Exmoor Pro as well as baselayers).
During the Arc of Attrition 100 mile race, I ran through sunshine, rain, gales and freezing temperatures and throughout the whole race I wore one baselayer and one waterproof shell. I managed my temperature throughout but taking off gloves, hats and venting my jacket. It was simple, effective and most of all, my chest and arms were the only bits of my body that was still “comfortable” by the end!”

How much does it weigh?
From just 214g for men’s S.
What is it made from?
100% nylon recycled from ocean waste, with an ultra-thin 3-layer hydrophilic membrane and a PFC-free C0 DWR coating.
How waterproof and breathable is it?
The Exmoor PRO has a 20,000mm hydrostatic head rating (waterproof) and a 50,000 MVP rating (breathability).
Your jacket is treated with a durable water repellent (DWR) layer that causes water to 'bead' on the surface rather than soaking in. DWR treatments slowly wear out over time which can cause it to start absorbing water and lose breathability.

How do I wash it?
Please follow the washing recommendations below.
Preparation: Close all zips/Velcro, empty pockets, and pre-treat stains if needed. Run an empty wash first to clear residue.
Washing: Machine wash on a gentle/delicate cycle (30°C) with a specialist waterproof detergent like Grangers Performance Wash. Do not use normal detergent, fabric softener, or bleach.
Drying: Tumble dry on low heat or line dry. Low heat tumble drying can help reactivate the DWR coating. Avoid high heat.
Reproofing: Over time, reproof with a product like Grangers Repel to restore water beading. Or use Granger 2 in 1 which both cleans and reproofs your jacket!
How often: Wash only when needed, if dirty, smelly, or when water stops beading on the surface. Frequent washing shortens the life of the DWR coating.
How long will the DWR coating last?
The PFC-free DWR treatment provides long-lasting water repellency, but it will wear over time. Follow the washing instructions and reproof as needed to maintain optimal performance.
What size should I choose?
The Exmoor PRO is designed with enough stretch for layering over a baselayer or light mid-layer. Choose your regular running jacket size. Size up if you prefer a looser fit or want to wear multiple layers underneath.
Is the jacket suitable for ultra running and long-distance trail runs?
Yes! The Exmoor PRO 3L trail running waterproof jacket is designed for long runs, ultras, and multi-day adventures. Lightweight and packable, it meets most mandatory ultramarathon waterproof jacket standards.
Please check the mandatory race requirements for your specific race.
What weather conditions is it suitable for?
With a 20,000mm hydrostatic head rating and DWR coating it’s ideal for heavy rain and snow and high pressure, making it a specialist lightweight waterproof jacket. This combined with a exceptional 50,000 MVP breathability rating means on warmer days and hard efforts you will remain comfortable and not claggy from sweat inside the jacket.
Can I use it in winter or cold weather runs?
Absolutely. With a breathable waterproof running shell, it keeps you dry while allowing sweat to escape, making it ideal for winter running and unpredictable UK weather conditions. Layer over a baselayer or light mid-layer for extra warmth.
How packable is it? Can I fit it in a running vest or backpack?
The Exmoor PRO is highly packable and folds into its own pocket. It fits easily into running vests, waist packs, or backpacks, making it perfect for ultras, trail runs, and multi-day adventures.
The WrapSnap stow system allows you to quickly store the jacket around your waist like a bumbag so you don’t have to keep stashing it in your pack during changeable weather and showers.
Does it have ventilation features for regulating heat?
Yes, the jacket features ventilation poppers for temperature regulation during climbs or high-intensity efforts. Combined with a high performance, hydrophilic, extremely breathable 3L membrane, you stay comfortable on long runs.
Is the jacket PFC Free?
Yes, the jacket is made from 100% recycled ocean waste nylon and uses a PFC-free C0 DWR coating, giving you a high-performance, eco-conscious running shell.
Does it have storage pockets?
Yes — hand pockets to allow you to carry gloves, hats, gels, or small essentials while running. You can also pack the jacket away into one of these hand pockets into a nifty pouch.
Can I adjust the hood and cuffs?
The adjustable hood and thumb loops provide extra coverage and comfort in harsh weather, while anti-slip shoulders help keep the jacket in place during long runs.
Is it suitable for men and women?
Yes, the Exmoor PRO comes in men’s and women’s specific fits - not unisex! Designed for trail and ultra runners with enough room for layering over baselayers or light mid-layers.
How should I store it when not in use?
Store in a cool, dry place away from direct sunlight. Avoid compressing the jacket for long periods, as this can affect the DWR performance.
Can it be used for other outdoor sports?
While optimised for trail and ultra running, the jacket also works for hiking, fastpacking, and general outdoor activity thanks to its lightweight, breathable, and packable design.
