Review on 🚰 Top-Rated Collapsible Water Bottle BPA Free (10-Pack) for Gym, Sports, Teams, Hiking, Camping, Biking, Outdoors, Beach, Traveling, Yoga & More! by George Ahmed

I've found pinholes in some of my bottles after normal use (I wear them when I walk, so they only literally pop up when I'm holding them in my hand or hands). washed). Even if they don't have a proper hole, they leak easily around the lid. You cannot "walk” with them, otherwise the water will drain out from shocks. Wearing it at a 90 degree angle can also cause leakage. I like that it folds up when empty. So I'm still using it - just realizing that in 2 hours of walking I'll probably lose about 1 ounce of water just from leaks.
