But the soles started rubbing off after only a couple months and now its uncomfortable to wear them because the loose materials rubs blisters on my feet. This is the perfect lightweight fleece headband. They are good shock absorbers. First, fulling charge the battery it will be workout at least 7-9 hours and up, it only take 1-1. Works out great. Is so perfect ! I highly recommend these The headband is similarly well padded, and Ive worn them for about 4 hours straight to chat whilst gaming while barely noticing them. They are lightweight and yet sturdy, and I like the sole design and their comfort. This sauna suit works really well.
