Light Up Hat

This beanie hat has an inbuilt headlight.

The hat itself is basic woollen beanie hat, but in the turnup, there is an LED light.

The headlight is activated by a button in the middle and pops out of the frame for USB charging.

The hat is very convenient no hands needed light for finding things or putting up a tent at night and somewhat less bulky than head lights, the downside is you can't adjust the angle so have dip your head further than a head light. 

The only other downside I see is warm summer use but yet to experience that. 

This light is not going to blind people or bring down planes, but it's bright enough to be very useful.

I got this or these hats (1 Grey and 1 Black one) as a gift from friends for Christmas

Russian Headgear

This is sold as Russian Tank commanders hat or helmet

A quick bit of research would suggest however its a paratroopers helmet worn by the airborne division of Russian Army during parachute drops. The Russian airborne division is heavily mechanised and they do drop vehicles with people inside them unlike most other armies, so perhaps it's both.

I normally consider helmets as a rigid head covering, this one, however, is a soft helmet, heavily padded in the ribs to protect you against impacts with hard surfaces.

The helmet is not mine and normally left at the entry stair to the owner's attic room which has many low beams so is ideal headwear.

Cossack Hat

This is a Russian army cossack hat

Made from sheepskin, this tall cylinder of fur is joined at the top with a fabric circle emblem.

This hat is also known as a Papakha in Russia however there are two different styles of Papakha, this one is the Papaha, the other is the Kubanka which is a shorter version, but basically the same.

The Cossacks were an independent nation which got integrated into the Russian nation, not in a good way, so the Cossack army fought against Russia, for Russia, played both sides, helped and hindered the Germans WWII, helped and hindered the Americans in WWII, helped the British fight communism and much more.

The Cossack Army ceased to exist after World war II, however, a law was passed just before the end of 20th Century as the Soviet Union ended allowing Cossack to exist again and they now deal with local Administration. 

They still wear this style of hat 

Camo Ushanka

This camo pattern ushanka is probably a perfect hunting hat, however never been hunting so could be worst hunting hat ever for all I know.

Also for some reason the double ear flaps I find make this hat a little comical, but they may have a purpose, perhaps to protect the ears for the noise of the gun or just extra ear warmth.
