The MTI Kids' Reflex Personal Flotation Device is wonderful for your kid if your family enjoys boating, paddling, or rafting trips all summer, and it's incredibly adjustable if you want to use it as a spare when your kid invites a friend without a PFD. There are eight adjustable points to ensure a secure fit for a variety of body shapes, and its v-neck and large armholes prevent uncomfortable rubbing overtime. MTI made it out of fabric that's soft and supple to the tough. The cargo pocket is large enough for smartphones, and the zippered pocket has a whistle for signaling.
