These pants are awesome. They protect your legs very well for welding. If you use your knees for low level welding, brick work, tiling, carpets or roofing, your knees will wear out before these pants do.

Got this my 85 year old mother who has macular degeneration. She is able to read her books and daily paper as well as resumed her embroidery. Highly recommend.

This was one of the best earpiece experiences I have ever had. I used it at gym and work. It was awesome! Incredibly good sound, especially for its size. The battery life is amazing. Charger is easy to use, and when it comes off the charger, it is on, connected and ready to go. I also use this earbud when ever I drive. I can have a conversation with others in one ear and still be able to hear anything that goes on the road. Definitely will be buying more for gifts!
