I know a guy who wears them doing outdoor manual labor and he says they definitely help. Just a fan but it evaporates sweat to cool the body. But if you’re not doing manual labor, you can just wear shorts, t-shirt and sandals, which might be just as cool.
I’m not sure how noisy they are so might be kind of odd if you’re in a crowded place. I guess you can try one out at the store.
If there is a freon heat pump like an actual AC has, it would need a backpack sized Li Ion battery to go with it to get an hour or so of operation.
They are just fans.
My husband uses them and they’re a godsend (he’s in construction, working outside). He particularly loves the Burtle brand.
One comment mentionned sound. There are 3 fan speed levels, the slowest one is like humming, the fastest makes some noise, but nothing that would surprise people.
They just recently released the futons with built-in fans. I wonder what those are like.
The guy that runs the yakitori truck near my place wears one. We were chatting about it the other day and he said it’s been great so far.
Yes they really do work. I was sceptical at first but it’s like carrying your own personal fan around with you all day long. I wouldn’t necessarily advise going outside in the middle of the day and doing heavy manual labour then, that’s what siestas are for, but they would give you a degree of protection even then.
I use the Burtle Aircraft range and you really do get what you pay for. Several friends bought cheaper brands and ended up going with Burtle in the end. As far as I can see most Burtle jackets are aluminium lined which helps reflect a good amount of heat from direct sunlight. The air layer being blown over you inside the jacket cools you down and provides another layer of insulation from direct sunlight.
I like the full sleeve versions with a hood but if you prefer short sleeves or vest type that may suit you better. Burtle batteries and fans are a tad expensive but they are good quality made in Japan not cheap knockoffs from China. Many Burtle jackets have a mesh pouch in the back you can place the soft gel packs you put in the freezer for extra cooling.
I wish they’d make a crotch and arsecrack version…
I’d recommend a PCM cooling vest–it’s good for at least an hour, and it’s going to make a much bigger difference. I got a thermapparel one–it’s pricy, but I think it’s worth every sen.
They do work! I have a vest and a full tsunagi/jumpsuit – the vest actually works better for me, it’s possibly just a sizing issue but the tsunagi one can sort of deflate and stick to my shoulders. I wear it for lighter farm work during the hottest part of the day and it makes it bearable.
They’re just fans, but they’re awesome. I used to use one, except…
a) They don’t work very well, if you’re carrying a backpack. The straps/backpack cuts off the airflow. This was the main reason I stopped using mine – I have to carry a backpack as I move around. For this year, I’ve switched to using a “neck fan” instead.
I still use mine when I’m out and about and don’t have to carry my backpack.
b) They do generate a bit of noise, but nothing that would bother the people around you. I would use mine while commuting on the metro too. The side effect of this, for me, was I would talk with a slightly louder voice.
I highly recommend getting one with a hood. it makes a world of a difference. You’ll want one that is just a little larger, so there is space for the air to circulate. It isn’t quite as effective if the jacket is fitting.
To save some $, I bought a Burtle jacket, and fitted it with a set of fans that ran off a usb power bank instead. While I’m sure Burtle fans/battery system is worth the money, I didn’t like the idea of being vendor locked into a specific battery/charger system. Do note that different jacket manufacturers use slightly different sizes for their fan system, so you’ll want to measure and check that.
They are just fans and godsend for people who have to wear (construction) jackets. For walks, why bother wearing a jacket at all?
I would actually consider the fan-pants, anyone use them? I don’t mind my upper body sweating too much, but preventing underwear from getting soaked 5-10min after leaving the house would be amazing.
I looked them up and the thing is, the fans are located outside the thighs – does that really keep the… Umm.. family jewels cool?
I just asked the other regular (who is wearing one) next to me at the izakaya, and he said yes and threw it over my shoulders. Definitely felt cooler.
How in he—- you think they’re gonna fit an aircon into a jacket? Yes, just two little battery fans.
They’re loud and annoying af, some of my coworkers would wear them in the office when they come in from the field and you can barely hear yourself think. Don’t know how good they are cooling wise, but they’re definitely loud
Am i the Only one who thinks its absolute instanity that the construction people or the traffic dudes don’t get to use shorts? I understand that there are rules but it must be torture. Where I’m from, if it’s hot in the summer it’s short and a bright orange shirt or whatever. I swear, Japans obsession with looking professional is beyond ridiculous.
I’m sure they work wonders but… you’re going to look like some kind of Mega Man villain, fyi. Are you ready to make that trade-off?
They’re just fans. ‘Air conditioning’ relies on heat exchangers to cool air at the expense of heating something else, which those jackets don’t do.
They are fan powered. They help facilitate the evaporation of sweat which cools you. If they were to use freon to cool you, it would have to have a 5 kilo cylinder attached to it, which I’m not thinking anyone wants to do.
