I'm normally 3XL and bought a 6XL to ensure it covers my usual Damart (grade 5) thermal vest and my Spar staff freezer fleece. Not tried it on whilst wearing those yet but seemed it would be just right although may need to discard the fishing waistcoat in favour of a small shoulder bag to carry my bits and bobs (forceps, styptic pencil, smartphone remote, shot, etc). Did find my USB 500000mAh power pack wasn't up to the job (faulty/dead and now binned) nor did my handwarmer/power packs hold enough charge to operate it BUT I did obtain a new 20000mAh one from Argos (£30) which I have had running,bwhilst on a coat hanger, on the blue setting (coolest?) for 12 hours and was still going strong.....😊😊 BTW mine is a £50 from Amazon jobbie and has separate heat controls (buttons) for full front and full back heating.....

f0r me id have worn it under a fleece , next to t shirt for two reasons , one its nearer the body ,two your fleece over it would hold the heat in better

The truth is brands overcharge. And it's not ok. We should have good products for normal prices, not either okeish or good but expensive or cheaply made but cheap.

I used something identical last winter it was brilliant like you I found sizing very silly certainly go two sizes bigger very warm under your fishing coat or wind proof hoodie still going strong this winter £20 can’t go wrong

I hear people complain when it’s too lose because the heat actually escapes. Prob better off with it a little light then lose

I have one of these very impressed, not warn it fishing yet but work outside on a fishery and it's been bang on 👍👍

wow brilliant.

Would it not be better to put the vest on first?

my light keeps flashing red, white and blue and does not get warm. What am I doing wrong?

battery power pack is extra £15 plus --- not inc. so its £35

Looks great but It’s not safe in rain, fine in most cases but you need to keep it dry

Bought one gilet like it, a thermo fusion brand one from ideal world and it didn't last me one year. Problem was the wires connecting the power button came off. Bought a new power button from ali express hoping I could fix it to no avail as the wIres were so flimsy so ended up throwing the gilet in the bin. Would never buy one again especially as most of what I see are cheaply made in china. They are great n warm when they working tho.

Is it safe in rain over a tracksuit ?

Hi do you have a link?

Maybe a link to what you bought would have been an idea

do u have to connect it to a power bank or can u straight connect it to an charger with a plug

Can it be connected directly to a transformer?

Can you check how many heat zones there are but I purchased one of these in the pictures it shows four but mine only has two

How long would the battery last on full power?

Does it still work mate? Anybody owned one of these for a while?

I paid £15 from ebay with free postage and packing and I'm XL but had to get a XXXL and even that was small so I told the seller and he said it would cost to much to send back so he gave me half my money back
