I tested the KETL RLT Merino Thermal Grid Hoodie through nine months of backcountry ski tours, cold hikes, and near-daily wear. It handled changing effort and repeated wear better than my lighter Patagonia R1 Air, but its 455-gram weight, poor wind resistance, and saggy hand pockets keep it from being the right fleece for everyone.

The HOKA Skyflow Jacket shines as a breathable layer for brisk morning runs and cool starts, but its light protection makes it a much tougher sell for harsh wind, rough weather, or bigger mountain days.

The Janji Zephyrunner is one of the better wind shells I’ve run in. It blocks enough wind to matter, breathes once the pace picks up, stays impressively quiet, and disappears into a vest. The catch: it wets through sooner than comparable running jackets.

The Patagonia Houdini Jacket is light, tiny when packed, and excellent at cutting wind, but it is not the do-it-all windbreaker its reputation might suggest. After hiking, backpacking, and running in it around Reno-Tahoe, I came away with a much more specific take on where it shines and where it starts to show its limits.

Some wind jackets feel great until you actually start moving. The KETL Breakwind stands out for balancing wind protection, breathability, and everyday usability better than most.
