Question: Is this product for kid or adult? I don't see any option to select size

You guys, wow, this product. This product, you guys, wow. You guys, wow, this product.I'm a novice swimmer, having taken only a few lessons in my adult life. I'm still uncomfortable with my breathing while swimming. Sometimes I can make it one length of the pool without making a breathing mistake (perhaps not enough hip twist), but more often than not I have to briefly stop swimming to collect myself or cough up an ounce of pool water.
After a couple of weeks of use, with minor water coming in through the top (from splash - no leaks), I bought the snorkel dry top - and it works great. (See separate review on dry top, a separate product.
So I think this is a great product for training laps where you are focusing on a particular aspect of technique. I can see why some people use nose clips. Getting water up my nose was a bit of an issue after every few laps. But I think I will be able to adjust. I had no problem with the snorkel filling with water.
Swimming is a terrific exercise for me but unfortunately I never learned the proper breathing technique for doing the freestyle stroke. So I searched for a decent swimmer's snorkel and this product fit the bill. First, I use a separate swimming mask so I can see. And I use a nose plug because it's pretty impossible for me to use the snorkel without it. I'm sure I look like an alien with all this gear (lol!
I always liked the heart pounding breathlessness of it. So when I first started using the snorkel I felt like I wasn't even exercising. In fact I would look to the side to see if I was actually moving. There is an accessory available, the cardio cap, that I might try later on. This restricts the available air to some degree.This product seems very well made and does what I needed it to do. I am thrilled to be able to continue swimming following neck surgery.
I been using this for about 3 months now and I really like it. I started swimming for low impact exercise-- I have had two knee surgeries and a herniated and running is just not an option anymore.
I started learning to swim as an adult this past June so that I could enter a triathlon. (It was on my bucket list.) With a limited time to learn to swim before the triathlon, I kept having problems with the breathing technique. To keep from being frustrated, I found out that I could use a snorkel in the competition. It's the best purchase I ever made. It's easy to use.
Great fit, works well, easy to clean, perfect size, and fun to use. Nice to use on in a 50 meter pool or 25 meter pool.
I find this to be a great training aid for distance swimming. I've used it for over a month now and find it very comfortable and easy to get used to. While in use it is centered close to your eyes so you barely notice it. It's no hinderence to your vision at all. Some reviewers mention the need for a nose clip, but I have not found that to be the case. I recommend it just like it is.Finis Swimmer's Snorkel Blue Adult Sized
