You may get the view you are seeking from product photographs of the Sleep Master Deluxe, which is the same as the original Sleep Master, except for the additional earplugs pocket and carry pouch: http://www.amazon.com/Revolutionary-Patented-SLEEP-MASTER-DELUXE/dp/B00A8QMUIQ

Two pieces. The mask is just for the face with a elastic band that goes around back of head. Outfit slips over clothes and velcros up the back.

I just submitted a photo to be published of the back of mine. Hopefully that will help you and others looking at the product. It's silly that they didn't already supply that in the listing. It is down at the bottom of page next to the reviews. Looks like there was one down there but I provided a close up view that might help.

Unfortunately I can't see myself when I'm wearing the mask, but I think the pictured model's face is small. It does need to extend beyond your eyebrows and cheeks in order to block out light.

It's the complete mask. You will need your own head bands and your own hose.

Not sure what you mean by better picture. You can get closer to the subject with the stick thing. I personally find the stick things to be an annoyance and using one generally makes the diver one of the most dangerous creatures in the sea, as they tend to cut off other divers to stick their camera in front of everyone else, and they tend to sling them around like a club. I bought the mask in hopes of being less intrusive and obnoxious, but the hard frame fit poorly on my face and broke after a couple of uses.

It may be possible to covert it if you had the needed pieces but as it comes it is just behind the head.

Yes- i find this mask uncomfortable on my back or side The Velcro sticks out and gives me a headache

Yes, the expiration date should be on the back of the mask, as long as you bought a genuine mask from seller Rastsvet

I do not know about the picture but I did get the large size (6900) full face respirator, sometimes vendors list the same picture for all their listings.

The stretchwise headgear came with the mask when I ordered it. It is just the strap that goes around the back of your head rather than the full head gear. I am not sure if you need the full head gear but I think that might have come with the mask too.

It is a flat mask. It is large enough to not sit on your eyes. It is very comfortable

I uploaded a picture of the other side for your use. It will be available to see shortly.

I'll have to look when I get home. I can't remember, but I think it is on the front at the bottom. I'll check and let you know.

The masks look almost exactly like the picture. They cover roughly half of your face.
