CURE: Add a short piece of velcroe to the existing one.
CURE: This happened to me with a medium liner, but not with a large liner. I simply took a pair og scissors, folded the liner horizontally, & snipped a small half-moon section out where my perferial vision was. Works fine.
For some people, there is a problem with too much space in the chin area due to decreased size from false teeth.
CURE:Put a small piece of 1/4" foam rubber directly in the chin area to take up the slack. Also, if you have the eyelets put in, simply lace the bottom two sets of eyelets, which will snug in at the chin area.
For some people, there may be a problem with the helmet sitting too low for good eye vision.
CURE: Again, put in the eyelets, and only lace the top 2 sets of eyelets, which will tighten the top of the helmet more & bring the field of vision up higher.
If you lace all 4 eyelets, you have to either remove the velcro completely [not suggested] or simply fasten the velcro & then have someone lace it up for you, as the lacing will be outside the rear pad. I have been using my Bogu & making personal modifications to suite my own features. It is very comfortable when fitted properly as it should be. I have done this with the intention that I don't plan on letting anyone use my Armor, as I have it just the way I like it,......get the point.
I hope this helps you, as education is the biggest part of the battle.
Sincerely, Paul Oliver.
