Objective: The goal was to measure how effectively each jacket blocked wind, a crucial factor for maintaining warmth and comfort on blustery running days. Wind resistance ensures the jacket can serve as a reliable barrier against harsh conditions.

Method: Jackets were tested in a wind tunnel at speeds ranging from 10 to 30 mph, simulating conditions runners often encounter. Volunteer testers also wore the jackets during outdoor runs on particularly windy days (15-25 mph wind speeds).

Outcome: The Salomon Men’s Standard Bonatti Jacket scored the highest in wind resistance (10/10), thanks to its advanced windproof membrane. The Montane Minimus and Baleaf Waterproof Lightweight Windbreaker also excelled (both 9/10). The Little Donkey Andy Insulated Thermal lagged slightly (7/10), likely due to its heavier fabric that allowed some air seepage.

Objective: Lightweight jackets are essential for running, as they minimize additional load and boost mobility without hindering performance.

Method: Each jacket was weighed and compared both before and after being worn in real conditions. Volunteer testers provided additional feedback on perceived weight during extended runs.

Outcome: Both the Montane Minimus Waterproof Jacket and Salomon Men’s Standard Bonatti Jacket scored top marks (9/10) for their featherlight designs, which felt barely there even over long distances. The Little Donkey Andy Insulated Thermal, designed for colder days, was significantly heavier and scored the lowest (6/10).

Objective: Durability tests assessed how well each jacket resisted wear and tear, particularly from repeated use, abrasion, and exposure to elements like rain or harsh terrain.

Method: Jackets were subjected to abrasion tests using coarse sandpaper to simulate backpack or long-term friction. Testers also ran through outdoor trails with dense vegetation, stones, and branches, recording signs of wear after 10 sessions.

Outcome: The Salomon Men’s Standard Bonatti Jacket and the Windrunner Hooded Windbreaker Anthracite showed excellent durability (9/10), resisting scrapes and maintaining structural integrity. The Little Donkey Andy and Proviz Reflect360 Running Jacket received slightly lower scores (7/10) due to visible stress on stitching and fabric after extended use.

Objective: Breathability is critical to prevent overheating and excessive sweating during high-intensity runs. The aim was to assess how well the jackets allowed air circulation and moisture vapor to escape.

Method: Runners wore each jacket during a 5K run in mild (60°F) and warmer (75°F) weather. Sensors measured interior temperature and humidity levels to evaluate how effectively heat and moisture escaped.

Outcome: The Salomon Men’s Standard Bonatti Jacket stood out again with high breathability (8/10), owing to its strategic venting zones. The Montane Minimus also performed well (7/10). However, heavier options like the Little Donkey Andy Insulated Thermal and Proviz Reflect360 Running Jacket struggled in warmer weather due to limited ventilation (6/10).

Objective: To examine how efficiently the jackets managed perspiration and kept testers dry during strenuous activities.

Method: Jackets were worn in a controlled setting while testers ran on treadmills under simulated humid conditions (indoor temperature set at 80°F and 75% humidity). Time to moisture absorption and drying was recorded, and testers provided feedback on comfort.

Outcome: The Salomon Men’s Standard Bonatti Jacket led again (9/10), showing excellent moisture-wicking capabilities and quick drying times. The Baleaf Waterproof Lightweight Windbreaker also delivered above-average performance with a score of 8/10. The Proviz Reflect360 Running Jacket and Little Donkey Andy Insulated Thermal lagged with lower scores (6/10), as sweat tended to linger on the interior, reducing comfort over time.
