The warm jacket i am using from Ravean is men down heated jacket. it comes with the battery bundle. The jacket is pure magic. For those , or for people like me who lives around the super cold areas where the blood can turn ice, this jacket is a blessing
The jacket gives me access to control the internal temperature. there is a range in temperature which goes like -10° F to 55° F.
Along with this, there is a hood that can be removed and add as i like.
What i love is how light this jacket is, it doesn't make me feel suffocated weather and work so good.
To get the jacket warm again, there is a battery and charger too
