TheFeed promotes two flasks, the SkyFlask and SoftFlask, for different running needs. The SkyFlask is ideal for long runs with its 500ml capacity and comfortable handheld design. The SoftFlask is suited for shorter runs and speed days with its smaller 250ml capacity and lightweight design.

Not all flasks are created equal.

Some are better equipped to handle a long run — with bigger capacity and a comfy grip that won't fade over the miles. Others are better suited for speed day, with enough capacity to keep you quenched without slowing you down.

That’s why we’d recommend keeping these two flasks in your rotation.

The Feed SkyFlask - 500ml

Best for: Long runs + handheld hydration

The SkyFlask gives you 500ml of hydration without the bulk of a traditional handheld bottle. The adjustable strap cinches securely around your hand, so you don't have to spend the entire run actively gripping it.

And because it's soft, it gets smaller as you drink.

Comfortable handheld: The adjustable strap fits securely around your hand for an easy, natural carry.

500ml capacity: Enough hydration to take you farther without reaching for a full vest.

Collapses as you drink: No more sloshing or bouncing around as it empties.

High-flow, self-sealing bite valve: It handles mixes, powders, and even thinner gels without a fight.

Packs down small: Once it's empty, fold it down and tuck it into a vest pocket or kit.

A great option when a full vest feels like overkill.

The Feed Softflask = 250ml

Best for: Shorter runs, speed days + carrying extra fuel
