Handy tips: Don’t put sleeves in the washer or dryer. We encourage you to dip, soak and hand wash any sleeve on their own.
The Training Mask Vent works great to for my job as a dog groomer, keeping hair, dander, and dirt out of my lungs. And then it helps me with training in the flat state of North Dakota.
I've tried several masks and found this one the absolute best. Bought my first one nearly a year ago and wore it out even though I had purchased several different brands in the interim, the best of these being less than satisfactory. So when the Vent Filtration Trainer became available at 30% discount, I promptly bought another one. This is the best mask on the market for anyone seeking workout enhancement while engaged in filtered breathing. Def recommended.
I love it. It was a great investment. It really helped boost my endurance a lot.
