Description

The non-medical V4 Mask is a two-layer mask similar to our V3 Mask (3 layers) in that it's a good option for people who want to sing, talk, open their mouths wide to laugh or who have facial hair or beards. Most (but not all) people will find they can open their mouths really wide without this mask slipping off the nose or above the chin. It features soft & comfortable adjustable ear loops and a lanyard for convenient wear.

The new nose bridge in the Flannel V4 Mask design is seamless and sits at a slight recess behind the rest of the mask; this design may work better for folks who’ve found it difficult to find a cloth mask that prevents their glasses from fogging.

The Flannel V4 Mask is made with two layers of 100% Cotton Flannel that’s OEKO-TEX Certified. If you’re wondering why we’ve chosen flannel (no, it’s not because we’re based in Seattle!) here’s the scoop:

We were honored to play a very small role in a recently published research study: Filtration Efficiencies of Nanoscale Aerosol by Cloth Mask Materials Used to Slow the Spread of SARS-CoV-2 published in ACS Nano. As you can read in the acknowledgements of the study, our small role was to send fabric samples to the researchers for testing.

As mask designers, we continually look forward to further research investigating potential mask materials. There’s always more we can learn; scientists and researchers are working overtime on behalf of their communities, countries, and the world on various projects related to COVID-19 and our collective human response to this pandemic.

We've worked with a fabric mill on a 100% Cotton Flannel fabric for our V4 Reusable Cloth Face Masks; the design of this fabric is intended to have a chaotic web of fibers, which could create more surfaces with which aerosolized particles could interact, as indicated as a possibility in the study. Our 100% Cotton Flannel is produced in an OEKO-TEX Certified fabric mill. Please note that this is not a medical grade fabric. Click here for the exact specifications of our 100% Cotton Flannel Fabric.

Like our bags, our masks are satisfaction guaranteed; we welcome you to emailus@tombihn.com whether you love your mask and want to recognize our talented sewing crew or there's something not working for you.

Our innovative ear loop and neck lanyard material is comfortable, conforming, and stretchy — but it’s not the scratchy elastic that’s typically found on masks. Even when worn around the ears, we (and others) find our material to be quite comfortable for longterm wear. As we mentioned, the ear loops and neck lanyard are both adjustable; you can shorten or lengthen them. We find the neck lanyard to be a convenient feature when we go out for walks. If no other people are around, we can let the mask hang around our neck and against the sternum; if we see another person coming our way, it's easy to very quickly grasp the ear loops (without touching the fabric of the mask) and put the mask on.

Your mask will arrive with a metal nose piece inserted into the slot that can be bent to conform your mask over your nose. By leaving the nose bridge slot open on both ends, we’re giving you the option of customizing the nose bridge to work best for you — you can replace the included metal piece with a different nose bridge material if you’d like a softer or firmer fit.

To wash your mask, see the CDC: How To Wash Cloth Face Coverings guidelines. We also recommend washing your face masks in a reusable mesh laundry bag; this will prevent the ear loops from getting caught on other stuff in the washer and dryer and will help protect your mask. If you’re looking to avoid wrinkles, machine wash your masks, shape the mask, and line dry per CDC Guidelines. Removing the twist-tie piece (use a pair of tweezers to pull or push it out) will help the nose piece last longer. Please download and review this PDF for our full warnings & instructions for use.

CHOOSING THE RIGHT SIZE OF MASK
 

To determine which size you need, take a flat ruler and place it next to your nose. Measure from the bridge of your nose to the point of your chin.

Choose Small/Medium if you measure LESS than 4.5” / 115mm

Choose Medium/Large if you measure MORE than 4.5” / 115mm

And if you measure exactly 4.5" or have facial hair, we recommend choosing the Medium/Large size. The ability to adjust the fit of the mask also means that some folks may be able to make a larger size than normal work for them. For example, the best size mask for for a person whose face measures 4.25” is the Small/Medium, but they can likely wear a Medium/Large with a good secure fit by tightening her ear loops.

RETURNS & GUARANTEE
Our masks are satisfaction guaranteed. Please emailus@tombihn.com if you're happy with your mask *or* there's something that doesn't work for you. We want to hear from you!

For the health and safety of our crew, we can’t accept physical returns, repairs or exchanges for/of these masks. Any issue with materials or workmanship on these masks will be evident immediately; beyond your immediate inspection of the mask upon its arrival, the mask is not covered under our Lifetime Guarantee.

MADE IN U.S.A. (AND WHAT THAT MEANS)
Some of you will ask why our masks (or our bags, for that matter!) are more expensive. Our business model is unusual: we are designer, manufacturer, and direct retailer and our entire company shares the same 16,000 square feet in Seattle, the city with the highest minimum wage in the United States. We're also a Certified B Corporation. The contract manufacturers we work with are also in Seattle. In short, our labor and overhead costs are likely significantly higher than that of a business who manufactures their products overseas.

WARNINGS AND INSTRUCTIONS FOR USE
We recommend that you read our Warnings & Instructions For Use. If you need more copies of the Warnings and Instructions For Use to distribute with masks that you are providing to others, please download this PDF and print additional copies on your home printer.

These guidelines are based on this FDA document; the guidelines may be subject to change. Please refer to the FDA website for the most up-to-date information.

Enclosed Face Masks are NOT Intended to Provide Liquid Barrier Protection.

This mask is not a surgical device or a respirator and should not be used as a substitute for either of these devices.

Not for use in any surgical setting or where significant exposure to liquid, bodily or other hazardous fluids, may be expected.

Not for use in a clinical setting where the infection risk level through inhalation exposure is high.

Not for use in the presence of high intensity heat source or flammable gas.

100% Cotton Flannel. Note: These masks are not made of medical grade material.

For adult use only. Wash these masks according to CDC washing guidelines prior to first wear. Wash routinely depending on the frequency of use. Do not microwave. Do not put in the oven.

Use of this mask is intended to be an addition to and not in substitution of all other measures recommended for the prevention of communicable diseases.

If irritation occurs, discontinue use.

If unsure, consult your personal physician before wearing.

When washed and dried, secure the clean mask to your face to cover both your nose and mouth.

WARNING: Gaps between the mask and your face, or a loose fitting mask, will reduce the effectiveness of the mask. Once secured, refrain from touching the mask and your face in order to adjust its fit. Any hand contact with your face, or the mask itself once donned, can increase your risk of contracting or communicating an infectious disease.

Actual Tears of Joy - You Need This Mask.

I bought this mask earlier on in the pandemic and love it so much. In a foolish act of kindness I gave mine to my partner when he lost his, and I never got it back. I hadn’t been able to remember the brand of mask this was for months and I just stumbled upon it! I sincerely started to tear up.

I initially purchased one for my walks because it was easy to place on and off - the adjustable straps are such an amazing design. However, it quickly became my go to because it seals better on the face than any mask I have tried, and I’ve tried a lot.

Call it my security blanket, but no mask was ever as good as this one. I’m excited to try the newer versions as well. But 3. BOOKMARK THIS PAGE. And stay safe out there.

I so want to give this mask five stars, but....

It is just shy of the perfection that is, in my humble opinion, the V3 three-layer mask.

And what is the difference, you ask? The material. There's something about the material in the V4 that seems to attract fuzz and such to the inner surface that can make it a bit disgusting, and leaves me having to inspect and pick at it before putting it on for the day. All of my masks are washed weekly and air-dried on a rack, I don't want to risk the elastic getting damaged by repeated exposure to dryer heat. The material of the V3 is much less problematic for picking up fuzz and hair on the inner surface.

I have seven each of the V3 and V4, I love and use them both. Currently I'm using the V4, if pandemic conditions worsen in my area I'll switch back to the V3.

One thing that I absolutely love about the V4 is the little lip around the aluminum bridge strip sleeve, it makes it very nice for positioning.

Best for skiing

I have several v4 masks that I wear while skiing. I use a freshly laundered on each day. They are very comfortable and keep my face warm as a secondary benefit. Before I got the v4s, I used a v3 for skiing and find the v4 much better. I wear glasses and goggles with the mask and have not had any fogging issues due to the mask. The mask does get wet from breath and dripping nose, but are comfortable all day on the slopes.

Great mask

I have several of these masks & a couple of the V3 masks.

My husband & I both love V4 mask. It fits well, it’s comfortable, keeps our glasses from fogging up and it’s been great over the winter.

The downside is, as it’s getting warmer in California this mask can get pretty hot. I really hope you make the V2 (large) in black! I ordered the small, but it didn’t fit.

Overall, we love these masks!

Very Uncomfortable Mask

The quality/build is great but I cannot stand wearing this mask for more than an hour. It is very hot you cannot communicate with anyone while wearing the mask unless you scream.

The mask is also a lint magnet so be sure to carry a lint roller with you if you plan on carrying this mask in your pocket.
