THE STORY
Woolrich, the original American outdoor brand meets Airinum - an innovator of today’s urban outfit.
Celebrating a very long history of such iconic designs as the Buffalo and Hunting Checks, the Limited Urban Air Mask is yet another testimonial of how Woolrich has pushed the boundaries of what to wear for generations.
This time, through an air mask: made to keep you safe in the 21st century, Woolrich and Airinum aim to keep people protected from every kind of elements, from cold weather to urban pollution.
A powerful utility for the new century developed in Woolrich’s historic check patterns, bridging Woolrich’s American heritage with Airinum’s innovative Swedish functionality.
ABOUT WOOLRICH
Woolrich was established in 1830 in north central Pennsylvania by founder John Rich. Today, it is the oldest American outdoor clothing brand, encompassing two distinctive labels: Woolrich, the contemporary high-end outerwear line distributed worldwide and Woolrich Outdoor, designed by the Japanese partner outdoor specialist Goldwin.
With 190 years of experience and a rich American heritage, Woolrich products integrate the brand’s historical identity with a contemporary interpretation. The original Woolrich Arctic Parka, introduced in 1972, is now considered the quintessential downparka and is an internationally recognized brand icon and symbol.

The airinum size guide
To find the correct size, we recommend to combine the two measurements below, the weight measurement and the eye-chin distance measurement.
1 WEIGHT MEASUREMENT
The weight measurement is strongly correlated with the length and size of the face, making it a great measurement for mask sizing.
- Use a weight scale to find out your weight
- Compare the measurement to the table
Recommended Size | KG | LB |
---|---|---|
L | Over 75 | Over 165 |
M | 50 - 75 | 110 - 165 |
S | 30 - 50 | 65 - 110 |
XS | 12 - 30 | 26 - 65 |
2 EYE - CHIN DISTANCE MEASUREMENT
The eye - chin distance measurement is a very accurate method for estimating the correct mask size.
- Use a ruler and measure the vertical distance between your lower eyelid and you chin
- Note that this is easiest to do in front of a mirror or with the help of a friend.
- Compare the measurement to the table in the picture below

Recommended Size | CM | IN |
---|---|---|
L | Over 11.8 | Over 4.7 |
M | 10.6 - 11.7 | 4.2 - 4.6 |
S | 8.6 - 10.5 | 3.4 - 4.1 |
XS | Under 8.5 | Under 3.3 |
If you get diffrent recommendations from the 2 methods, follow the one from the eye - chin distance measurement. If your weight or eye-chin distance is on the borderline, pick the bigger size to ensure a better fit.
