Nathan has been a big-time player in the hydration game for at least as long as I’ve been a runner. Their newest option, the Aerozip Vest, launches this spring and really provides a minimalist approach to hydration.

Oftentimes when we (and other websites) talk about hydration packs, the conversation is about storage. This is obviously great for runners who need a lot of fuel — whether it’s for a long race or a run deep in the backcountry. There is nothing worse than being caught out there unprepared because your pack couldn’t handle your needs.
But not every run is a Columbia Gorge waterfall trek, and not every race is an ultramarathon. Those shorter runs — even road runs — have hydration needs too, just in a different way. On these outings, I’ll often go with a handheld or a full trail vest. Neither is inherently bad, but sometimes a handheld feels like not enough and a full vest feels like overkill. I think this is where the Aerozip Vest comes in.
Storage is pretty decent overall. It holds the two included 17-ounce soft flasks, but instead of a ton of extra pockets and bulk, it leans into a streamlined fit. You get a mesh back panel, quick-fit cords for micro adjustments, and a zipped front design that focuses on ease of movement and minimal bounce. That’s not to say it doesn’t have storage — it includes four expandable mesh pockets and one zippered pocket for easy-access essentials. Storage just takes a bit of a backseat to the minimalist flair.
This is a category I’ve been thinking about for a while but didn’t fully appreciate until trying it. The Aerozip 1L Vest is a great option for runners who need a little something when it comes to hydration — whether that’s training runs, half marathons, or even a streamlined full marathon setup.
It comes in both unisex and women’s sizing, which makes sense. In the women’s vest, the flask pockets are strategically placed slightly lower for a more comfortable fit.
If you can find one in-store, it may be worth trying it on to dial in sizing. I found my standard size worked well, but it’s definitely a tight fit – mostly by design. If you’re between sizes, it’s worth making sure you have the right compressive fit. Too tight and you lose the comfort factor — which kind of defeats the purpose of a minimalist vest.
Not every mile calls for a full kit, and not every runner wants something sloshing in their hand. The Aerozip hits that sweet spot — simple, secure, and ready for the miles that fall in between.
