## Description

The FITLY FLASKS Combo offers three collapsible water bottles for running, designed for athletes who demand lightweight, portable hydration without bulk. This soft flask running set includes 5 oz (150ml), 8.5 oz (250ml), and 13.5 oz (400ml) sizes that fit easily in jersey pockets, running belts, and pants pockets. The handheld running water bottle design features thermoplastic polyurethane construction that is BPA-safe and PVC-safe for safe hydration during marathon training, cycling, hiking, and skiing. Each soft water bottle running flask shrinks as you drink, creating an airtight seal that prevents sloshing and reduces bulk. The flexible water bottle compresses to a minimal size when empty, making it easy to carry in running vest water bottle holders or standard pockets. The intelligent bite valve mouthpiece has a shortened design that allows faster liquid flow, while the enhanced circular lock mechanism provides leak-proof closure during transport. These collapsible water bottles for running are freezable to double as ice packs on hot days. The running water bottles clean quickly after use and work effortlessly during activity. Ideal for runners, cyclists, and hikers seeking pocket-friendly hydration solutions.

Review: So handy - You can vary these anywhere. They don’t leak and no off flavors
Review: Lightweight, small 'footprint - For walks around the neighborhood or short hikes, I hate taking a bulky waterbottle. I don't like having a backpack, fanny pack, or crossbody for sensory reasons, so having a small, lightweight way to carry some hydration was on my list of 'things to find.' Well, I found it! The selection of sizes allows me to take just what i need for that day's particular 'adventure'. Once I have finished the water, it is like I am carrying hardly anthing at all (unlike a water bottle). It easily fits in my pocket full and empty. Drinking from them took a few tries to get used to you, you do indeed have to bite as instructed which feels like a no-no based on past mouthpieces that would tear. These hold up to the biting. I also did a few vinegar rinses to be sure there was no silicone flavor, and that worked well. The mouthpiece does not give or leave a silicone or plastic flavor either, which was important to me. I love these!

### ⭐⭐⭐⭐⭐ Great for cycling
*by I***S on April 12, 2023*

Purchase these to put gels in for long road bike rides. I bought all three sizes not knowing what I would need. But even the large 13.5 Oz container fits perfectly into a jersey pocket. Easy to use and clean.
