I must say, absolutely LOVE the #LENPOW Running Belt Waist Pouch! The belt is adjustable from 25.9" to 42", so it is great for anyone in the family. Waist pouch is made of Nylon/Lycra fabric. Zipper area has 3M Reflective Strips to help provide safety at night. This wonderful waist pouch will hold most smart phones and has an earbud hole so your earbuds can be run directly from phone in waist pouch to your ears. Keys, identification, credit cards, passports, etc., can also be stored in this slim, sleek waist pouch during your form of exercise including walking, running, biking, going to the gym, whatever you like. I use mine while working in my flowebed and doing other yardwork. This waist pouch is so lightweight, I hardly notice that it is there. Waist Pouch is water resistant (sweatporoof and rainproof), it will keep items inside of it dry while you are exercising, however it is not fully waterproof. So don't leave it out in the rain with your things still inside. This waist pouch is one of my favorite items that I have ordered. It is very handy and so far, I use it every day, everywhere I go! I HIGHLY RECOMMEND this item!! #RankBoosterReview #Sponsered
