Question: Any suggestion for size for scrawny 5 ft and 97 lbs
Document: I'm 5-10 210 lbs and the X-Large was the perfect size for me. Does not ride up like my old floatie vest.
I did not experience this problem. I believe it is due to oversizing the vest. I am 5'11&#34; and weigh 175 lbs. I purchased a medium and it fit perfectly.
The snorkelling vest was very comfortable to wear. Just the right size. Only used it for a couple of session and totally liked it.
Really great quality vests that are easily packed for trips. Just make sure select a right sized and snug fit size as otherwise an oversized vest tends to float up and pushes against your chin which is a nusiance
We just returned from a trip to Roatan and all I can say is I am so THRILLED that I had this vest! I'm not a very strong swimmer and just recently began to enjoy snorkeling. This vest was a God send for me! I'm 5'8&#34; and about 145 pounds and the size small fit me perfectly.
I bought the extra large size, I'm 6'-2" about 220lbs and the vest fit perfect! It is a great design & very comfortable too. I haven't yet used it snorkeling yet, but read some of the other reviews that said it has a tendancy to ride up if inflated. I am going to take the advice from another reviewer, and intend on removing from my old vest the adjustible crotch strap and sew same to this vest.
I originally ordered the large size vest but it was too small and I had to return it. I needed the vest sooner than later and the vendor allowed me to order the X-Large and get a refund on the original Large purchase when I shipped it back. They were very easy to work with.The vest itself is well-constructed and worked great. We went to Maui and I used it probably 6 times snorkeling off the beach.
You definitely want a snug fit; too large and it rides up under your chin. The company accepted the return of the larger vest with no problem at all.It is too bad they do not offer this vest for children, but perhaps the reason is an adult should never depend upon a flotation device to keep your child safe. I am so much more comfortable wearing this vest and that means I get to enjoy the snorkeling that much more!
Wore this snorkeling in the Bahamas just before Thanksgiving. Fits great. Looks great. I didn't really have any problems with it riding up and it was easy to inflate to just the right buoyancy for me. Much better than the strap on bladder type of vest.
When you snorkel, you need HIGH visibility... people with jet skis racing by CANNOT see you with the Neon color on the CHEST side of the  which is IN THE WATER!!
