I recently purchased the FITLY Soft Flask - 12 oz (350 ml) for my running and hiking activities, and it has quickly become an indispensable part of my hydration setup. This soft flask offers a range of features that make it ideal for anyone needing a compact and efficient water bottle for outdoor activities.The design of the FITLY Soft Flask is excellent. The flexible material allows the bottle to shrink as you drink, reducing its size and minimizing sloshing. This feature is particularly useful during runs or hikes, as it ensures the flask remains compact and comfortable to carry. The flask is also lightweight, making it easy to include in my hydration pack or running vest without adding unnecessary bulk.The build quality is impressive. The flask is made from durable, BPA-free materials that are safe and long-lasting. Despite being soft and flexible, it feels sturdy and capable of withstanding regular use. The wide mouth design makes it easy to fill and clean, which is a significant advantage over some other hydration solutions.The cap and nozzle design are both practical and user-friendly. The cap seals tightly, preventing any leaks, and the nozzle allows for easy sipping on the go. It's simple to operate with one hand, which is perfect for maintaining momentum during activities like running or cycling.One of the standout features of this soft flask is its portability. When empty, it folds down to a small size that easily fits into a pocket or pack. This makes it convenient to carry as an extra water source or for use in situations where space is at a premium.Overall, the FITLY Soft Flask - 12 oz (350 ml) is a fantastic hydration solution for runners, hikers, cyclists, and outdoor enthusiasts. Its durable construction, practical design, and compact size make it a highly convenient and functional water bottle.
