Why We Like The Nathan VaporAiress 3.0 7L Hydration Pack

When we're striding out for double-digit miles, we kit up with the Nathan VaporAiress 3.0 7L Hydration Pack. The low-friction, performance material wicks away sweat and dries off quick to keep us cool, light, and chafe-free, while the adjustable straps let us dial in a perfect, bounce-free fit. Equipped with seven pockets and a two-liter bladder, this vest keeps us stashed with all the fuel, layers, and water we need for our long trail runs.

Totally love it!

The VaporAiress 3.0 is awesome! The sizing is perfect and it is very simple to use. I wear it while mountain biking and while running. No water sloshing around. No leaks. Easy to use while on the go. Just perfect!

Awesome new design

Used this new purchase for my first half marathon this past weekend. Ended the race well hydrated and never noticed this lightweight pack. Lots of pockets for gel, AirPods and other stuff. I am a new Nathan convert! Love it

Front pockets too small for bottles :(

Very comfortable, but the biggest bummer is that the front pockets don't work for bottles. I'd rather use bottles than bladder so I can better manage my liquid calorie intake. Had I known the bottle pockets were so much smaller than the previous packs, I never would have purchased this one. Overall comfort is amazing. Nathan has nailed that. All their packs are so comfy. The hiking poles loops are quite small and my elbows bump it as I run so that's not super awesome. That's one thing Nathan packs haven't nailed, pole carrying. Great product, comfortable, just a few annoyances which will prevent me from buying this style again.

Very comfortable

It is very comfortable. No jiggling of the water & roomy pockets. The water pouch leaked on my first outing, but a new pouch was sent within days. It was very comfortable during a recent half marathon & will work perfectly fo my upcoming full.

Great Features

The vest is comfortable, the pockets are great and the bladder holds a good amount. I love the design and thoughtful details like the magnetic latch for the straw.

Need a vest for an ultra? Look no further

So much room for everything I could possibly need. I absolutely love it

Kinda cheap... only buy if it's deeply on sale

The velcro is very cheap and the first time I used it to open the pocket it tore. The front pocket bungee is also broken. I'm glad I didn't pay full price for this!

My new favorite pack

[This review was collected as part of a promotion.] I love this pack. It lays flat on my back even with the bladder full. It has plenty of pockets for fuel, keys, extra sunscreen, phone, etc.

Running Vest

I gave it 3 stars because it was supposed to be unisex, not womens. I bought two different sizes and NONE of them fit.

Nice and Light

I have the Nathan Pinnacle 12 Liter Women's Hydration Race Vest and I feel the pocket that holds the water on that pack has a little better fit then the Vapor Airess. I like the Airess for lighter runs. I was able to stuff a jacket in the bottom pouch today and it worked great. I got this vest at a super good price and for the price it was a great deal!
