The treatment used is ‘Ion-Mask’ I believe there was a typo in that web feature. It is our proprietary water repellency treatment at molecular level, and is featured as standard on our Attack glove, stealth bomber, and Unabomber glove. Whilst it offers a certain amount of protection against the elements, it is not a fully waterproof treatment.
The attack glove has been a very popular seller, with its cuffless design, and single layer palm making it a very light, second skin style glove. However I would not want to recommend it to you on the premise it is a waterproof glove
