Very comfortable and good for people who wear glasses
I do find this one of the better fits and my glasses don’t steam up as much or as fast as when using other types of mask. The quick drop down feature is actually much more useful than I expected, highly recommend.

Great Mask
Best fitting and most comfortable mask I have had. With the circular dust filters and adjusted properly you can breathe freely and still work hard. Using a pole sander is much more appealing than it used to be with a mask. With the solvent filters the airflow is more restricted but paired with goggles spray painting, using contact cement or acetone isn’t so much a worry now. I am really taking care of it as I feel it is something I won’t work without now in toxic airborne particulate and vapour environments. I can smell and taste the difference. Night and day. Get one you won’t regret it.

Excellent mask. Replaced a worn out one.
This mask is a replacement for the 6300 that I have been using for about 5-6 years. The elastic on the older mask became threadbare and cannot be replaced. I'm glad to say this mask will accept replacement elastic judging by the design. The mask itself seals well to your face and the filters are extremely effective. I use organic vapour filters and prefilters and when spraying paint you cannot detect the small of the solvent at all. One huge benefit over the fabric type filter masks is that this type does not feel hot and wet on your face when the vapour from your breath builds up. It's worth knowing that this mask does not come with any filters, you'll need to buy them separately. If you're working in particulate environments then a prefilter is a good idea and these fit over the outside of the main organic filter.

Good but drippy in a cold workplace
Good fitting mask and having the clip to lower the front so you can talk/get a drink without stretching the elastic head straps is a massive bonus compared to the other version. My only issue is I work in a unheated indoor environment so this time of year the inside of the mask gets filled with your breath causing condensation so you drip onto your chest a lot and I do mean a lot. I have to walk around with a cloth in my pocket which is one of the only things that lets it down.

Perfect for under helmet fitment
Best price on the day, bought to go under my welding helmet without interference and is a perfect fit. Filters are easily obtained whilst the respirator is well designed and functional in all areas. Comfortable to wear for extended periods and doesn’t mist up the welding helmet lense.

The clip around your neck could be better instead of a hook.
Great design for how the mask drops easily when not in use. Should really come with a case. The clip for around your neck could be better.
