I have a sleep disorder which forces me to often sleep during the day. And the environment is very noisy! People can't imagine what it is like to sleep during the day when they are used to sleep at night, it's a nightmare, it's maddeningly impossible to get any long sleep due to various daytime noises, either because of neighbors or city traffic or building works.
I have tried pretty much all other solutions, including earplugs of all sorts and soundproofing windows, but this was not enough. Now, I combine the Hibermate and earplugs, and this works wonderfully well. The Hibermate alone does filter sound although not as much as earplugs, but more importantly it "muffles" the sound, so that it sounds like it's coming from further away than it is, and it dampens the explosive sounds. So sometimes I also use the Hibermate alone, but when I want to get a good long sleep, I use both the Hibermate and some earplugs. The Hibermate adds another layer to soundproof myself from the environment, but also it helps in keeping the earplugs in my ears (otherwise they regularly inadvertently slip away due to friction with the bedsheets).
The eyemask is also very effective at blocking light, even with curtains wide open, it's much more effective than any other eyemask I have tried (and I tried a lot!), although it is quite uncomfortable on the nose due to the pressure and its rigidity (the earmuffs are attached through the eyemask, so the eyemask presses against the face and nose), but between having a good sleep and having some uncomfort at the nose, the choice is quickly made. But still, if there is ONE thing I wish Hibermate would improve, it would be to cut a hole for the nose, it would be SO much better, but I guess it would be difficult to make the Hibermate be as robust as it is with less surface on the eyemask to sustain the tension.
All in all, it's an amazing product I can only recommend. I don't know why they are the only ones to make such a product, but it's a product of public utility. I consider this product so incredibly important for my sleep now after 3 weeks of use that I will be buying a second set just in case the first one breaks.
