The Perfect Jacket for Trail Running

"After a lot of research to find a rain jacket suitable for trail running, this is the best jacket I've found—and it's very reasonably priced for the quality! I tested it in the rain and in strong winds, and it held up really well; the breathability is top-notch—it doesn't feel like a sauna at all. The various design features—like being able to pack it into its own pocket, fastening it at the front with just a snap, or unzipping it from the bottom to access the bottom pocket of the hydration vest—are really great. The fit is perfect for wearing a hydration vest under the jacket and easily putting on or taking off the jacket if conditions change."

The Perfect Jacket

"I bought this jacket to run a 25K night trail run in the middle of March. It rained all evening, but I didn't feel the cold or the dampness at all with this jacket. It's really great."

Ariane X. (5/5)

isokore jacket

"I'm very happy with the jacket. It's very comfortable, warm, and waterproof. It runs a bit large, though, and it could use an inside pocket for a cell phone."

Stéphane D. (4/5)

Excellent jacket

"As soon as I bought it, I was able to test it in harsh conditions—in cold, windy weather below -3°C, then in light rain, and finally in the snow under my ski jacket—and I can confirm that it’s completely waterproof; the quality is top-notch. The reasons for deducting one star are as follows: - It’s difficult to roll it up into a bag, so it’s hard to do so while running; - I think it’s a shame there isn’t a small exterior or interior pocket; - There’s no reflective strip—it’s a shame the white lettering isn’t reflective either. . ."

Men's Jacket 15k

"I'm thrilled with this jacket. I've tested it in the damp weather of the North. It's very lightweight and comfortable to wear. It's excellent quality, and I love the color. My wife has the same one. The women's version is slightly different in color, so there's no risk of mixing them up! We highly recommend it!"

David C. (5/5)

Top quality!!

"A great jacket—I tested it in the rain, wind, and sub-zero temperatures. It has a roomy fit and runs a bit large, so I’d recommend sizing down for a more form-fitting look... Very satisfied with the quality and the fast delivery, but it’s a shame I had to pay for the return due to a sizing mistake..."
