Kailas FUGA Trail Running Soft Flask 500ML (AIR 8 IV)

I’ve tried a dozen different soft flasks, and this Kailas FUGA one is by far the best. The 500ML size is perfect for long trail runs, fits easily in my running vest’s front pockets, and the AIR 8 IV design means it collapses completely as I drink, so there’s no annoying sloshing or bouncing while I run. The bite valve is easy to use with one hand, no leaking, even when I’m bouncing down rocky trails. The material is durable and BPA-free, easy to clean, and doesn’t retain any weird flavors from my sports drinks. It also has a handy measurement scale on the side, so I can easily track how much I’m drinking. If you’re a trail runner, this is a must-have piece of gear!
