Respro Ultralight Mask (Black, Medium)

I ordered a medium thinking this would suffice the size of my face. Upon receiving this item, I realized it was a tiny bit tight for me. I messaged the seller to see if I could exchange for a different size. The message back to me is, "I checked over your order and see that you did order a Medium so the mask we sent was the correct one." Amazonusually will exchange without hassle. But if you're going to purchase this product make sure you know the exact size. Besides, at this point they really only have one size of the black mask. If I wanted a large, I would have to go for the olive color.

The mask itself and the valve are well made and seem to work well. But the behind-the-neck strap is a poor design (for me anyway) as the mask annoyingly keeps slipping off my nose.

it's just like every other one out there for 12.00 it to heavy

Lo uso para andar en bici en la ciudad y no respirar toda la contaminación de los camiones. Hay que acostumbrarse ya que restringe un poco el oxígeno.
