WHAT EXACTLY IS AN “IN-MOLD HELMET”?
An in-mold helmet is a helmet constructed with a manufacturing technique where the foam interior liner of the helmet is “blown in” while the hard exterior shell is still in the manufacturing mold.
- Light Weight. By fusing the liner to the shell during construction, the outer shell can be very thin and light weight.
- Well Vented. With an in-mold helmet, the manufacturers are able to create many more vents, and locate them all around the helmet, while at the same time retaining the structural integrity of the shell/liner combination.
- More Interesting Shapes. With in-mold construction, the helmet can have distinct angles, shapes, and certain features that make the helmet much more interesting and unique.
While in-mold construction was originally limited to high-end helmets, in-mold helmet construction now appears in many mid-to-high-end helmet models across bike, skate and snow helmets. If you want a very light weight helmet, with generous venting and unique styles and angles, then an in-mold helmet can be just right for you.
