I’m really happy with this hoodie! I spent weeks comparing all the heated coats and hoodies on amazon before deciding on this one. The customer service was fantastic when asking when my size would be available again. Within 10min they responded. It turned out they had one left and sent me the link to purchase it through amazon.This hoodie is very well made and true to their sizing chart. The material is thick and comfortable. The hood itself is a good size which is a plus. I really like having two inside zipper pockets as well.As for the battery I have had no issues and it lasts all night on one charge. I’ve gotten 4hrs on just high setting and up to 10hrs alternating from medium and low settings. I did purchase a second battery so I can always have one charged ready to go. It’s great you can use any power bank that’s a 5V 2.1A output for this reason. The battery that comes with it is lightweight and not bulky. I don’t really notice it much when wearing it.I was worried it wouldn’t get hot enough but this thing really does heat up nice. I usually put it on high for a few minuets then switch between medium and low the rest of the night unless it’s extremely cold, then I’ll leave it on high.Overall this was a great buy and I’m very happy with my purchase. It’s been below zero here most nights and I’m able to work outside comfortably.
