Satisfy HydraPak Soft Flask 2 Pack 500ml - Extended Hydration for Distance Running

The Satisfy HydraPak Soft Flask 2 Pack features 500ml soft flasks designed in collaboration with HydraPak to keep you hydrated on runs. Constructed from ultra-durable, abrasion-resistant, BPA and PVC-free TPU for reliable performance across training and racing.

Ultra-Durable TPU Construction

Constructed from ultra-durable, abrasion-resistant TPU material that's BPA and PVC-free. Each individual flask holds up to 500ml (17 oz) of liquid when filled. The flexible construction is easy to squeeze, compressing as you drink to reduce water movement inside the flask. This compression prevents sloshing during running, maintaining balanced weight distribution.

Large Opening with Leakproof Valve

Large standard opening lets you fill the soft flask easily with ice and drink mixes without requiring funnels or special tools. Leakproof high-flow bite valve auto-seals after each sip, eliminating annoying drips that waste hydration or wet clothing. The valve design allows quick hydration without breaking stride.

2-Pack for Extended Distance Capacity

The 2-pack format provides 1 litre total capacity across both flasks, working with running vests or belt systems for balanced front storage during longer efforts. The soft flask design fits comfortably in standard flask pockets without rigid bulk.

Are the Satisfy HydraPak 500ml Soft Flasks Right for You?

Built for runners tackling extended distances requiring 1 litre front storage across both flasks. The 500ml capacity per flask works for long training runs, ultra-distance efforts, or marathon racing where aid station spacing demands carrying substantial hydration. Ultra-durable TPU construction withstands the abrasion and compression of repeated use across high-mileage training blocks. The compressing design reduces water movement that throws off balance during technical terrain or faster paces. Leakproof high-flow bite valve auto-seals after each sip, preventing wasted hydration during self-supported runs where every millilitre counts.
