Review on 🏃 SLS3 Soft Flask Lightweight Compact BPA Free Hydration Water Bottle - 10 oz, Ideal for Running, Hiking, or Sports (Clear, Pack of 2) by Robert Long

Worked perfectly during my 50k Ultra race. I carried them in the front pockets of my Ultimate Direction running vest without having to take them out to drink. Just bite the valve, squeeze the bottles, and you'll have plenty of water. They were also quiet because no water was splashing. My only concern is the seams. I don't know how long they will last before they expire. I think only time will tell. I've only used them once.
