Why We Like The Osprey Seral 7L Pack
Osprey designed their Seral 7L Pack for mountain bikers looking for the minimalist fit of a lumbar pack, without sacrificing hydration or storage space on longer rides. The main compartment holds a 1.5L reservoir while extra pockets stash maintenance tools and snacks, and the contoured lumbar wrap delivers a stable fit even on technical terrain.

Needs improvement
My husband got me this to replace an older Osprey hip pack. I'm less than enthusiastic about this new one and may just continue using the older one. The front buckle pops apart unexpectedly quite regularly while riding, but thankfully hasn't gotten tangled in my wheel; same with his new one. The bladder does not fit right in the bag compartment. It's like they forgot to take into account the fact that it actually gets filled with water and extra space is required to accommodate this. After purchasing several other types of Osprey packs that I've been very happy with, this one is quite disappointing.

My bum bag!
My upper ribs will spasm on occasion when using a rucksack. The Seral 7 has proven to be comfortable and prevents the problem. Additionally it is quite capacious allowing the carrying of fluids and snacks. I really like it!

This is the second Seral
[This review was collected as part of a promotion.] This is the second Seral 7 I bought, this time for my friend because she has been complimenting mine so much. I love that I can take it biking or hiking. It is roomy enough for snacks and a light layer. The only negative is that the water hose does not stay in place and detaches easily from the magnet.
