FITLY Flasks Combo – 3 Handheld Collapsible Water Bottles for Running, Marathon, Hiking, Cycling (5/8.5/13.5 oz) – Blue

Compact hydration on the move

Meet the FITLY FLASKS Combo, a trio of handheld soft flasks designed for runners, cyclists, hikers, and marathon training. In a vivid blue finish, they tuck securely in jersey pockets, belts, or vest pouches, offering a lightweight hydration option without bulk. The collapsible design helps you stay agile from start to finish.

Smart design that minimizes sloshing

Each bottle collapses as you drink, creating an airtight seal that reduces water movement during activity. When empty, they compress to a small footprint, making them easy to stash in a pocket or running vest. Lightweight and space-efficient, they clean up quickly after use.

Sizes that fit your workout

Choose from 5 oz (150 ml), 8.5 oz (250 ml), or 13.5 oz (400 ml) soft flasks to match hydration needs and pace. For longer sessions or mixed workouts, the larger size can provide a steady supply, while the smaller options stay light for quick efforts.

Leak-proof, safe, and simple to clean

A redesigned circular lock provides a secure, leak-proof seal for pocket carry. The bite valve mouthpiece offers smooth sipping during activity and is easy to rinse after workouts. The bottles are BPA- and PVC-safe, ensuring clean-tasting hydration.

Durable, versatile material

Made from tough TPU that remains flexible in varying temperatures and can double as an ice pack on hot days, these bottles stay resilient during outdoor adventures. The bite valve design supports faster liquid flow, and the secure closure keeps hydration where it belongs.

What you can expect in real use

From a quick tempo run to a rugged trail session, the soft flasks adapt to your pace. They’re light enough to hold in one hand for a focused interval, yet sturdy enough to endure outdoor routes and chilly descents.
