Why We Like The Osprey Seral 4L Hydration Pack
Osprey's Seral 4L Hydration Pack provides a minimalist design for mountain bikers looking to carry the essentials on short- to medium-length rides. The main compartment houses a 1.5L hydration reservoir with room to spare for a multitool and a snack or two, while the contoured lumbar wrap delivers a stable, close-to-body fit on varied terrain.

I grabbed this to wear
[This review was collected as part of a promotion.] I grabbed this to wear at a race versus my backpack so I had more airflow. It fits great and is easy to cinch down to keep it from flopping after drinking some water out. Excellent product. Highly recommend.

[This review was collected as part of a promotion.] Great little pack. Simple and functional. Wish there was shove-it pockets or bunnies for attaching clothes to the outside. Cinch straps don’t seem to do anything.

Excellent warm weather biking bag
Fits like a glove, holds the essentials, has room on the strap to attach a small camera case, does not get particularly hot, thanks to air flow construction. Used on a bike tour of Cambodia (85-95 degrees F) and on day rides in New York (40-50 degrees F). Never used it as a hydration pack. Removed the bladder immediately. Instead carried sunglasses, large smartphone, snacks, small tube of sunscreen, passport, cash, electrolyte drink mix packets, bike multitool.

Great Pack!
This pack is great for short excursions. While it is a biking pack, I use mine for short hikes and snowshoeing. It has been awesome to use while recovering from a shoulder injury. It has enough room for water, snacks, and small essentials. I moved the mouthpiece closer to the belt buckle because it would disconnect from the magnet constantly when you move your arms. Also, a mesh pocket in the front would be great to quickly stash and access a cell phone. My biggest disappointment with this pack is the lack of a reservoir cleaning kit. It is very inconvenient to clean the small reservoir and dry it out. I end up using multiple reusable straws to poke into the reservoir to keep it open and allow air flow and get it dry. Would love to see a proper drying rack.
