The Feed Collapsible Supplement Funnel + The Feed Skyflask by HydraPak - 500ml
Product Description
Your hand cramps up gripping a rigid bottle for two hours. Then at the aid station, you're scooping powder that ends up everywhere except your flask while everyone around you fills and moves. Two different problems, same result: you're losing time and comfort to gear that wasn't built for the job.
This kit pairs The Feed Skyflask 500ml with The Feed Funnel — a collapsible soft flask and a wide-mouth funnel built to make every carry and every refill faster and cleaner.
Carry Lighter, Mix Cleaner
The Skyflask collapses as you drink, eliminating the slosh and hand fatigue of a rigid bottle. The Funnel's 70mm opening catches even oversized scoops cleanly, so your mix goes into the flask instead of onto the ground.
Built for Aid-Station Chaos
The flask's wide 42mm opening fills fast, accepts powders and ice without a funnel of its own, and locks tight with a leak-proof twist cap. Pair it with the Funnel for concentrated mixes or oversized scoops, and you're in and out of every stop without fumbling.
Packs Down to Nothing
Both pieces disappear when you don't need them. The flask folds flat and tucks into a vest pocket once empty; the Funnel's pliable silicone collapses completely flat and rides along in a pocket, box, or kit until the next mix.
The flask is manufactured by HydraPak using durable TPU with RF-welded seams — heat-fused rather than glued for stronger construction under repeated stress — and is BPA-free, PVC-free, tough enough to freeze or handle a summer 100-miler. The Funnel is made from FDA-approved, food-grade silicone, also BPA-free and PVC-free, so nothing contaminates your nutrition race after race.
Set it: Cinch the flask's adjustable strap to your hand size once before your race — it's ready every time after that.
Load it: Place the Funnel into your flask or bottle opening before scooping in your drink mix, especially for concentrated blends or oversized scoops.
Fill it: The 42mm flask opening and 70mm funnel opening handle mixes, powders, and ice at any aid station without drama.
Pack it: When empty, fold both flat and pocket them. Nothing here bounces, sloshes, or takes up space when it's not working.
Trail runners and ultra athletes have made soft flasks the standard for efforts where a full vest feels like overkill — and a funnel built for real scoop sizes is the detail that keeps mixing from turning into a mess. The Skyflask is backed by HydraPak's Beyond Lifetime Guarantee.
Stop fighting your gear at every aid station. Carry less, mix cleaner, and move on.

The Feed Funnel + The Feed Skyflask FAQ's
Everything you need to know about this product.
Both. The wide 42mm opening accepts powders and ice directly, and pairing it with the Funnel's 70mm opening makes concentrated mixes or oversized scoops go in clean instead of spilling.
No. It locks tight with a leak-proof twist cap, and the TPU body uses RF-welded (heat-fused, not glued) seams for stronger construction under repeated stress.
Cinch the adjustable strap to your hand size once before your race. After that first setup, it's ready to grab and go every time.
Yes. The flask is BPA-free, PVC-free, and tough enough to freeze or handle a summer 100-miler, and the funnel's food-grade silicone holds up the same way race after race.
Both pieces collapse flat. The empty flask folds flat into a vest pocket, and the silicone funnel collapses completely flat to ride in a pocket, box, or kit until your next mix.
