RZ Mask - M2.5 Reusable Mesh Air Filtration Mask

QUESTIONS ABOUT SIZING?SIZING & FITTING GUIDE M2.5 MESH MASK: 2 Strap System The RZ® M2.5 Mesh is a slightly different take on our popular M2 Mesh. Like all RZ Masks®, it features our standard F1 filters, blocking 99.9% of particulates down to .1 micron in size! Both the M2 and M2.5 feature the same highly breathable mesh fabric construction that helps to keep you cool on even the hottest summer days. However, rather than using the single strap closure of the M2, the M2.5 opts for a flexible dual elastic strap system with quick-release buckles. This adds an extra touch of security and comfort, making it ideal for exercise and movement, or when you must wear your mask for an extended time.
