I work in home care. It's hot every day, and I cycle to my clients' homes, sweating buckets even when assisting with bathing. I made a back cooler that I can wear on my back. I tried fans that go around the neck, but this one, which carries ice packs on the back, worked the best. Please use ice packs from your home. 20cm (height) x 16cm (width) Base price: 750 yen Shipping not included The shoulder straps use sturdy flat elastic. It's made of quilting, so the ice packs may melt and seep, but it won't soak your uniform, and besides, I'm already drenched in sweat, so it doesn't bother me. During care, clients ask me, "That's cute! What's that on your back? Valuables?" The ice packs spark conversation. This is made from leftover materials by my fellow helpers, so it's inexpensive. The heat will continue. Those in the same profession! Please give it a try. Handmade with a home sewing machine. It's different from mass-produced items. Please refrain from purchasing if you are concerned. Back cooler Cooling goods Ice packs
