FITLY Soft Flask collapsible running water bottle, Blue, 17 Ounces — lightweight TPU, bite valve

FITLY Soft Flask is a 17‑oz collapsible, BPA‑ and PVC‑free running water bottle designed to compress as you drink for quiet, low‑bulk hydration on the move.

Whether you run, hike, cycle or travel, the FITLY Soft Flask offers a lightweight, reusable option for carrying liquids without the bulk and bounce of a rigid bottle. Constructed from durable TPU and fitted with a bite‑activated silicone valve, this soft flask packs down as it empties, fits most running vest and belt pockets, and is simple to clean and store between uses.

How does the compressible design improve hydration while running?

The soft, flexible body shrinks as liquid is consumed, reducing slosh and keeping the flask close to your body so it doesn’t bounce. This helps maintain balance and comfort during fast or technical movement.

• Compresses to minimize wasted space and sloshing
• Molds to hand, pocket or vest for secure carry
• Lighter feel compared with hard bottles at similar capacity

How do I drink from and close the FITLY soft flask?

Drink by gently biting the silicone mouthpiece and squeezing the body for a controlled sip; there’s no need to unscrew a rigid cap. A circular lock and the intelligent bite valve reduce leaks when stowed in a pocket or bag.

• Bite valve for on‑the‑move sipping without unscrewing
• Leak‑resistant closure with secure locking mechanism
• Easy to open, use and reseal during activity

Is the material durable and safe for repeated outdoor use?

The flask is made from thermoplastic polyurethane (TPU), which combines flexibility with resistance to wear and punctures. It’s free from BPA and PVC, and can even be frozen to chill a drink or serve as a compact ice pack.

• Durable TPU construction for frequent use
• BPA‑ and PVC‑free for safer reuse
• Freezable for chilled drinks or compact ice storage

What activities and carrying options suit this flask best?

Designed for active days, the FITLY Soft Flask works well for short‑ and long‑distance running, hiking, cycling, skiing and travel. Its slim, flexible profile fits front, side or back pockets of vests and belts for quick reach without breaking stride.

• Fits most running vest and belt pockets
• Ideal for runners, hikers, cyclists and skiers
• Packs flat for easy storage in a pack or drawer

Who is this for? The FITLY Soft Flask is aimed at active people who want a fuss‑free hydration option that’s lightweight, packable and low‑profile. Choose this flask if you value minimal bulk, quick access while moving, and a reusable bottle you can stow compactly when empty. It’s a practical pick for everyday training, race day, day hikes, or travel where saving space and weight matters.
