Pros: What’s good about the Zephyr Pro?

The Zephyr Pro 12L running vest is a great option if you are looking for a lightweight vest with the capability for either hydration bladder or bottles. I have found Camelbak’s bottles to be the best of any brand, and their hydration bladders have been standard for years.

The Zephyr Pro has 4 points along the sides to adjust the fit, and two more across the chest, which is why it makes sense to release it as a unisex option.

The pole quiver on the back is stowable and also completely removable. I really like that option. It keeps you from having to bungee your poles down when you aren’t using them.

There are different pockets on the front which can handle your hydration bottles, phone, fueling options, or bits and bobs you don’t want to keep on your back.

Cons: What’s not so good about the Zephyr Pro?

The vest has different pockets up front and in the back, but nothing along the sides. This allows it to be more adjustable, but it also means you need to put your phone either next to a water bottle, in the back, or only use one bottle and the other side for your phone. It wasn’t an issue for me, but if you need extra pockets, take that into consideration.

If you need your poles to be on-the-run access, you will need to go with something like the Dynafit Ultra or be able to dislocate your shoulder while speeding down the hill… but I hope you aren’t willing to dislocate your shoulder. Just slow down and unsling one side.


I took this pack on a 7 day trek on the Camino de Santiago. I was able to carry everything I needed for that (we stayed in hostals, so I didn’t need a tent or food prep kit). The fit was perfect and didn’t have issues with chaffing or rubbing.

I would recommend this vest to someone who is interested in a good pack for extended hiking or ultra running. Camelbak has their “Got Your Bak™ Lifetime Guarantee” which covers all reservoirs, backpacks, bottles and accessories from manufacturing defects in materials and workmanship for the lifetime of the product. That makes it even easier to recommend.

*I received this pack free of charge in exchange for an honest review.
