Hi James,
I recently attended a close quarters battle (CQB) training course with a company here in the United States. After the course, I was very kindly ‘gifted’ a ‘Breath of Life’ emergency mask. I was very grateful for this gesture, and curious as to this product. Luckily, as a volunteer fire fighter, I got the chance to try this mask’ effectiveness during one of our training sessions, which can be seen here.
I must say, I was incredibly impressed with this product, and as a long time reader of your excellent site, feel it maybe of interest to your readers also…
I should mention I am not ‘affiliated’ to this company or product in anyway, merely just aware of it, and lucky to have had the chance to try it out.
I hope these links maybe of some use.
Best wishes, – Toby C.
