Yes. It has a knob-adjustment / ratchet sizer thingy on the back of the inner strap.
The above answers are correct, but they forget to mention that you must first fold the tabs in half, so that they are inserted into the slots with the narrow side in first.

I used the Sthil version for decades and the Echo for a little more than a year. Debris on or in the screen has never been an issue. The breathability is great, and I've never felt like my vision was impaired. I think the biggest plus are the ear muffs. Surprising how much more fatigued you get without ear protection.
Yes it can be removed .
The Echo Safety Helmet System is made in Taiwan.
1. Hold safety helmet with inside facing up and the front pointed away. Place the suspension in the helmet with seat band facing away and nape strap facing up; insert one suspension tab into its shell slot. With thumbs on top of tab, press firmly until the tab snaps fully into place. Repeat procedure for each tab. 2. Adjust to head size (fasten firmly to the wearer's head to ensure maximum protection) A. Slide Lock (standard suspension) Insert the numbered end of the nape strap through the guide tabs of the adjustment end engaging each set. Proper fit is achieved by aligning desired size with the raised marks on the center guide tabs. To disengage the locking teeth for larger head-size adjustment, squeeze the area marked "PRESS" while pulling the numbered end. Release at desired size. B. Mega Ratchet (ratchet knob suspension) Turn the ratchet knob counter-clockwise to adjust the open suspension. Place the helmet on head and tighten the ratchet knob by turning clockwise until the helmet is secure and comfortable. DO NOT OVER-TIGHTEN Hope this helps!
