I initially posted this helmet for general information on another post but since finding more information on it and its history i feel it would be less confusing to post it on its own. (MODS, feel free to delete previous post if necessary). The helmet in discussion is on the left.
This helmet was produced by Kirsa and although Russian prodcued, were issued to the Czech Republic to pay off a debt. Aswell as such helmets being sent, 6 Mi-35 combat helicopters were presented.
"This is the Russian-made Kirasa BSh-E helmet, manufactured by "Kirasa" in Perm.
In July 2003 a set of 2000 such helmets (alongside with other equipment) was supplied by Russia to Czech Republic to repay its debt. It is likely the helmets were delivered with vz.95 and snow covers. Two sizes were supplied, 1st in 54-57 cm and 2nd in 58-62 cm.
The shell is very similar in shape to Schuberth m826 and is made of Aramid fiber fabric and organic matrix using prepreg technology. On the back rim, there is a producer marking, stating in cyrillic "Kirasa BSh-E-1".
Liner is very similar to that seen on Sestan Busch BK3. On the pictured helmet, the chincup is made of two straps, but more common is the plastic chincup variation.
There is also a Czech sticker inside of the shell, stating that the useful life is 5 years (when the ballistic protection is guaranteed). With delivery in 2003, no helmets are supposed to remain in usage with Czech army. "
The above information was found on the following website: Composite Helmet, Ballistic helmets, Military helmets CZECH helmet, Kevlar helmetcomposite helmets index which i believe a member of this forum is responsible for, so thank you
This helmet is the 54-57cm with the two piece chin strap and not the chin cup variant.
Thanks for looking
