HydraPak SoftFlask - Collapsible Nutrition Flask (150ml or 250ml) - BPA Free, Easy Open Cap, Foldable, Lightweight

These soft flasks have been a total game-changer for my running and biking routine. I started using them to make my own homemade gels, and it’s been one of the best decisions I’ve made—not only for convenience but also for saving money. I no longer need to buy expensive commercial gels, and I have complete control over what goes into my nutrition. The flasks are easy to fill, don’t leak, and are super comfortable to carry whether I’m on a long run or a ride. The material is flexible without feeling flimsy, and they hold up well even after repeated use. What really stands out is how easy they are to clean—no lingering residue or hassle, which is huge when you’re using sticky gel mixtures. Overall, they’re reliable, cost-effective, and perfect for anyone looking to switch to homemade fueling. I’d highly recommend them to endurance athletes who want a simple, reusable solution that just works.

First Impression: I picked up the HydraPak SoftFlask for trail running and mountain hikes where carrying gels or liquid fuel can get messy. Out of the package, it feels impressively light and flexible — like a soft balloon made from durable material. The build quality is excellent: welded seams, no chemical smell, and the cap design looks well-engineered for quick access. It’s small enough to fit in a vest pocket or even the waistband of running shorts without bouncing. Real Experience: On the trail, this little flask shines. The soft body collapses as you drink, so there’s no sloshing sound or wasted space — a small detail that makes a big difference on long runs. The bite valve delivers just the right flow, and the wide mouth makes refilling gels or electrolytes easy. Cleaning is straightforward, and the material doesn’t retain odors even after several uses. I’ve dropped it a few times on rocks, and it shows no signs of wear. The only con: if you overfill it, it can be a bit tricky to close tightly until you get used to it. Helpful Conclusion: Perfect for runners, cyclists, and hikers who want a reusable, ultralight way to carry nutrition or hydration. It’s durable, leakproof, and folds down to almost nothing when empty — ideal for minimalist setups. I’d definitely buy another one in a larger size for longer runs.

I’ve been using this flask for last few months. I have 2 of them. I use 1 of them for normal water, other one for electrolyte drink mix. It fits perfect in my naked band pocket. Easy to clean, leak proof. I will recommend it

Works very well for reusable gels --- easy to refill and everything. Only thing is that it is a bit big so unless you are riding a century or at least 50+ miles, its a bit inconvenient to squeeze everything out so gel still gets wasted. Aside from that, works well. Does not affect taste, I like the regulations. Nozzle good for gels!!!

Been going strong for year, bought a 2nd for more volume for longer runs. Works great in my Naked brand running belt, one on each side. Tips: Don't completely full, leave just a 1-2 cm at top, squeeze air out then cap. Full/full and they can pop lid off if you like bend at waist and squeeze it. Other tip, I rinse and put in fridge, no grime. I generally just use water, but If I use electrolytes, I rince, the add 1-2 tbsp. of vinegar, squash around, rinse and fridge. I fyou want to air dry, I just slide it over a butter knife propped up to hold it open. No scum/smell/tastes in a year. Great price, good product, perfect for running belts/vest.

Great to DIY your own energy gel. Can fit a lot into just one flask instead of carrying multiple packets, and there’s no trash to deal with.

These flasks are so much better then expected! My husband uses them for his long distance running to hold his homemade energy gels. There is no plastic or chemical smell or taste. And they are surprisingly easy to clean! The chia seeds he adds to his gels typically make a mess, sticking to the sides making cleaning a pain. But not a problem with these flasks! Just fill with warm sudsy water, shake it a bit and squirt it out. So easy!

They need to use the previous caps. These new caps are very unreliable. I flew with them with contents and the ziplock back was a sticky mess. In my jersey pocket, same thing - they leak. My fridge also need to be cleaned more regularly due to the leaking of the new caps.

As described. Small enough to fit in pocket. Gives me three mouthfuls of liquid. But the plastic chemical smell is disgusting. And effects the taste of the liquid. I have washed it out numerous times and have left it without the lid on for over a week and even though the smell is not as strong it’s still there. I’m hoping with time it will eventually disappear.

A disaster of a product. The twist nozzle opens in the same direction as the screw cap lid itself, with the same amount of strength - this leads to me unscrewing the entire lid off each time I do it single handedly on my bike, getting gel spilling all over my bike. Not recommended unless you like gel all over your body. Or if you don't mind using a gel bottle that needs 2 hands to open.

all good

Excelente, fácil de agarrar y llevar.

ジェルを複数持って走る人には必須のアイテムです。 フルマラソン時、ジェルで消化不良を起こしてましたが、この商品に、ジェル3個を水で薄めて入れてたところ、消化不良が起きなくなりました。 1点だけ、素材が柔らかいので、蓋を開ける際、少し注意が必要。 蓋の横の硬い部分を持って開ければ、吹き出すことなく開けれます。
