Perfect fit for my vest
Slipped right into my Nathan x Hydrapak flasks and now I can drink on the move without yanking bottles out. Long enough to reach with the vest zipped. Bought the two pack so both flasks are covered.

Works as described
Straws fit snugly and the extended length is great for trail running. Wish they came with a cleaning brush, but for the price I can't complain much.

Solid upgrade for marathon training
I've been logging 40+ mile weeks and these straws have held up through countless refills and freezes. The bite valve feel is the same as the stock one, just longer. One tiny gripe: they can pop loose if you don't seat them fully, so double check before a race. Otherwise, exactly what I needed.

Good but slightly stiff
Function is fine and the extension reaches perfectly over my shoulder. The material is a bit stiffer than the original straw so it took a few runs to get used to. Would buy again but not perfect.

Exactly what the vest needed
Converted my handheld flasks into vest hydration in under a minute. No leaks, easy to clean with a pipe cleaner, and the extra length is just right for a 6'1" runner. Great value for two straws.

Fit issue on one flask
One straw sealed perfectly but the other wouldn't seat in my older flask model without leaking. Customer service says it's designed for the newer Nathan x Hydrapak versions. Keeping them since one works, but check your flask version first.

Essential for ultras
Used these on a 50k and sipped hands-free the whole way. Durable, no off taste, and cleanup was easy.

My daughter got me into trail running and these made my old flasks actually usable with my pack. Simple product, does the job, arrived fast.

Cheap fix, big difference
For under $15 I basically got a new hydration setup. Sipping while running feels natural now and I drink way more on hot days. Highly recommend for anyone with Nathan vests.
