Its great. I love them. My fingers are big and don't move like they use to.so this works so easy for me.

I bought this hat in a beige. I love that it covers my entire face and neck really well but I have a very hard time keeping the hat on my head. I think the cap part of it is too shallow or the band is too narrow in diameter. Even when I pull the draw string to tighten it, it doesn't help. My head is not particularly large and I can usually fit into a one-size-fits-all type hat. I wish they would adjust this, because the hat itself is a great idea for those of us who have had melanoma and are sun phobes.

This looks nice right after I put it on and does wash well.  It almost immediately slips off the back and down around my shoulders when I sit down and my furniture is on the small side.  I would definitely not recommend this to anyone.

When you tighten it on your head, it just loosens itself immediately. So it slides down your forehead. So it doesn't work as intended.

There are a bunch of sharp corners around the head size adjustment slide that constantly dig into my neck if I wear these around my neck. That's a pain because I frequently push my headphones off my ears and wear them around my neck between video conferences or when someone comes in to my office to talk - these I'll have to take fully off.

wearable, but stitching around the neck is not desirable.

It's cheap and mediocre. Numerous annoying design qualities particularly around the implementation of the neck band. I should've bought the higher end product.

Not for large heads , small ear flaps and does not cover back of neck..

Good strap, but make it where it can be adjusted a little longer... Not everyone likes playing under their chin!

I wish the neck guard went down a little farther. Nice hat overall though.

It doesn't stay up!!  It stays bundled at the base of my neck protecting little.  It also doesn't provide any coverage below the neckline of a typical crew neck shirt so if you're wearing a v-neck, no luck there.  I had hopes for this little guy.  The fabric is too thin and slippery to gain any traction on the neck.  I definitely want something that will protect my neck, but this isn't the one.

This was the first E-Collar I ever bought. I figured it looked the most comfy and it wasss cheaper than other collars. If your dog has a short neck or maybe a short snout and you don't want them to reach their hind end or back area, maybe even genitals than this may work well. However for my 70lb Pitbull with a thigh lick granuloma, it did not. First, it took only a matter of a couple hours for my dog to figure out how to get it off his head. I then decided to tighten it so that it would be too much effort and he would give up. Tsk tsk tsk... to my enjoy he could no longer get it off. However, he then had the bright idea to use his nails to see if he could either break it or maybe even maneuver it. So what happens when a sharp pointy object forcibly contacts a thin piece of plastic covering a large mass of air? I'll tell you what happens kids... it goes bye bye. Like a balloon the thing sputtered, made a slight whip and flattened like a pancake. My dog then feeling very heroic and accomplished pulled it off of his head, kicked it away from his bed, and blissfully layed down with no more worries of this intrusive evil neck pillow that his beloved human dad decided to punish him with... point is, I bought a real cone.

It's way too tight around my neck when I try to wear it in a way that exposes my entire face.

Gives an extra inch or so for big necks.  Sometimes you can see it though when wearing it, hence the star taken off.  Sometimes tough to put on as well.

Does not fit my neck very well.  The large Velcro strap around the front is very stiff.  Overall, I just found it uncomfortable to wear.

My cat has squirmed out of several harnesses and eventually was able to squirm out of this too. It's just like slipping out of a t-shirt. The major problem I have is the neck strap is so wide that it goes up to his chin. My cat can't look down and turn the head.

Eh... I put this on and I have some resonance that is quite annoying at certain RPMs. I've tried a few things to tighten it up, but nothing has really worked. It's plastic, and not heavy duty at that (it seems to me).

I'll probably take it off this spring.
