Product Description
You're mid-run, digging through your vest for a gel packet you can barely open with sweaty hands, losing stride, losing focus. The athletes up front aren't stopping. They're drinking on the move, clean and fast, without missing a beat. The difference isn't fitness — it's their setup.
The Feed Softflask 250ml is the go-to liquid nutrition carrier for endurance athletes who want cleaner fueling and zero mid-race fumbling.
Collapses As You Drink As your flask empties, it shrinks with you — no sloshing, no bulk, no awkward half-empty bottle bouncing around in your vest pocket.
Locks So It Never Leaks The thumb-operated locking cap snaps open and shut with one hand, even mid-stride. Your shorts stay dry. Your pack stays clean.
Built for Real Nutrition, Not Just Water Designed specifically for liquids and low-viscosity nutrition — electrolyte mixes, liquid fuels, or plain water. Whatever you're running on, it handles it.
The flask is built from TPU — a flexible, food-safe material that's soft enough to squeeze easily but tough enough to survive hundreds of races. The self-sealing silicone nozzle means no dripping between sips, and the high-flow design delivers a real drink when you actually need it. At just 27 grams — less than an ounce — you won't even notice it's there until you reach for it.
Fill before your race or long run: Load up to 250ml / 8.5 fl oz with your electrolyte mix, liquid fuel, or water — then lock the cap. Tuck into your vest: Fits cleanly into most running vest front pockets, waist belts, and hip packs. Pro tip: Run both flasks — one for water, one for your nutrition mix — so you never have to choose between hydration and fueling mid-race.
Trail runners and ultra athletes rely on soft flasks to keep their fueling clean and their kit minimal. Coming as a 2-pack, you've always got a dedicated setup for water and electrolytes running simultaneously.
This isn't just another water bottle. This is your fueling system dialed in for race day.

The Feed Softflask 250ml FAQ's
Everything you need to know before getting started.
It's designed for water, electrolyte mixes, and low-viscosity liquid nutrition like drink mixes. If it pours, it works. Avoid thick gels — those are better suited for the 150ml nozzle flask.
Yes — at 210mm x 70mm it's sized to slide right into the front pockets of most major running vest brands including Salomon, Ultimate Direction, and Nathan. It also fits waist belts and hip packs.
Absolutely. The wide opening makes rinsing simple after every run. For a deeper clean, fill with warm water and a drop of dish soap, shake, and rinse. It's built to last hundreds of races.
Yes. It's made from TPU (thermoplastic polyurethane) — a flexible, durable, food-safe material that contains no BPA. Safe for everything you're fueling with.
Hard bottles stay the same size whether they're full or empty. A soft flask collapses as you drink, eliminating slosh, reducing bulk, and fitting snugly in a vest pocket the entire run. For endurance athletes, that difference adds up over hours.
