Nathan-VaporCloud-Race-Vest-2In today’s review, we’re going to take a look at the features and functionality of the Nathan VaporCloud 2-Liter Hydration Vest. Although grip bottles can nice for brief walks and jogs, and running belts can be nice for shorter distances, hydration vests leave both hands free, offer ample storage capacity, and give you store more hydrating liquid. If you’re going to be outdoors in the heat for a 30-minute run or on the trail for even just a couple of hours, a hydration vest is the most reliable and safest option.

Nathan VaporCloud 2-Liter Hydration Vest Features

The Nathan VaporCloud 2-Liter Hydration Vest proves to be one you can bring on day hikes, longer treks, road and mountain biking, and racing.

This breathability and comfort of this pack are not to be understated. We’re not alone in noticing (and loving) the VaporCloud’s near-magical blend of materials here, which don’t overheat you on your run.

The straps that run across your chest are elastic and easy to adjust. It offers a very snug fit, but don’t worry: it won’t choke you when your chest expands during parts of your run when you’re panting!

Planning an all-day trek? You’ve got a lightweight, reliable running back here. The Nathan VaporCloud 2-liter vest weighs just 1 lb 3 oz. (550g) and offers tons of storage options to hold your gear and necessities.

  • Includes five pockets on the front: Two drawstring pouches for the additional bottles, and three pockets of varied sizes
  • Zippered hip pockets for easy-to-reach protein and energy bars
  • Two pockets in the back, which would make a great fit for a rain cover, first aid kit, sunscreen, bug repellent, etc.
  • Includes a cord and hooks to hold trekking poles Nathan-VaporCloud-Race-Vest

That uncomfortable feeling of liquid sloshing around your back? Nonexistent with the Nathan VaporCloud. Every time you take a drink, you can easily pull on the straps that tighten the hydration bladder without interfering with its water flow. The load lifter also does an excellent job at preventing any ‘bounce’ or chafing.

Another thing we noticed is that the Nathan VaporCloud is much easier to clean than some other bags. Here’s a tips for you:

  • Fill the bladder (and attached tube) with hot water and soap.
  • Keep the length of the tube below the hydration bladder (for greater pressure).
  • Let the solution (or soap) run through the tube (by pressing down on the open spout of the tube).
  • Repeat steps 1-3 with plain hot water.
  • Invert the hydration bladder; dab dry with paper towel.
  • Shake the tube dry.


Also, you don’t have to worry about your own body heating up your water! The VaporCloud’s insulation prevents heat transferring from your body to your pack. We all agreed that this was one of the most notable and impressive features of this vest.

Any negatives?

The Nathan VaporCloud 2-Liter Hydration vest checks out on the essentials. It’s lightweight and has an optimum 2 to 3-liter capacity that will keep you feeling refreshed and hydrated even after several hours of physical exertion. However, this running pack is not waterproof. It’s breathability and comfort comes from this pack’s stretchy mesh material. It doesn’t keep the water out. Additionally, although we’re not saying this pack if for runners with a smaller for, bigger guys might want to go with a running hydration vest that offers a bit more room.


Key Takeaways


  • Plenty of storage space
  • Breathable material prevents overheat
  • Insulated bladder (major plus!)
  • Good hydration capacity (2 liters, plus room for two 20-36 oz. auxiliary bottles)
  • Great for running, riding, long trekking adventures when you need some gear, but not so much that you’d need dedicated running backpack
  • High visibility during the evening or other low-visibility times of the day


  • Not waterproof.
  • Size is on the slightly smaller side. If you’re a big, burly man built like a barrel-chested brick wall, this will probably not be the bag for you.

Final Thoughts

The Nathan VaporCloud 2-Liter provides well in comfort and hydration, making it a favorite among long-distance runners and hikers. The lightweight, breathable material and lack of waterproofing strongly indicated to us that this is best for daytime use during warmer and dry weather. As with all hydration packs, you need to protect what needs to stay dry, so if there’s any chance of rain showers, we’d choose a pack that’s waterproof. But all in all, the Nathan VaporCloud is a very impressive, top of the line hydration vest that can be used in a multitude of ways.
