THE VERDICT
The LEM Flow is a newcomer on the mountain bike helmet scene and hits the sweet spot between safety, comfort and value. It proved itself to be a comfortable helmet for extended rides and the ventilation was excellent on high-humidity days. However, the adjustable/removable visor is feels flimsy and felt like it could snap off with minimal pressure.
FULL REVIEW

Comfort

The LEM Flow’s key to comfort feature is the straps. The side straps are composed of one thin strand of webbing to make the straps comfortable. They laid flat on one tester’s cheeks and stayed secure on rough trail. Straps are spaced far enough apart at the helmet junction to not touch or chafe our tester’s ears.

The medium-weight padding is moderately plush and perforated. It performed admirably in absorbing sweat and mitigating forehead drip and one tester experienced no pressure points or discomfort, even on extended all-day rides.

Ventilation

The LEM Flow offers nineteen large air vents with the largest in the front to ensure a big gulp of air intake. An air channel and four generously-sized rear vents allowed for good airflow. One tester noticed that riding on warm, humid days, his head wasn’t entirely soaked.

Features

The LEM Flow size large measures 14.25 inches from ear to ear and 16.75 inches from front to back for generous head coverage. A bug-mesh liner molded into two of the front vents mitigate entry from flying insects. However, the bug mesh is only in the front two vents so technically bugs could enter from the rear—not likely while riding but possible on slow climbs or while stopped. The LEM Flow’s visor is adjustable and easy to fully remove without using tools. Some testers felt that is was a bit flimsy and felt like it might break off with just the wrong nudge of pressure.

Fit

The LEM Flow’s glove-friendly LEM FS2 fit system brings a secure, easy, on-the-fly customizable fit with micro-adjust dial fit system is simple and fast to adjust and can be done one-handed while riding. The ear straps are fully adjustable. 

One tester commented that fit was better than he had expected, even commenting that he has been through five helmets in eight years and always had to make several padding adjustments to get the right fit with each one. He stated that the LEM Flow fit perfect right out of the box.

Straps are adjustable at the ear and spaced far enough apart at the helmet junction to not touch or chafe testers’ ears.

Weight

With excellent head coverage the LEM Flow size large weighted in at only 11 ounces (317g), making it the lightest of all the helmets in the test.
