Tripwrote a review of Osprey Packs Poco AG 20L Kid Carrier on June 3, 2019
Familiarity: I've put it through the wringer
I was gifted the Poco AG Plus, which has a bit of additional storage, but is functionally the same as the Poco AG.
Every kid-carrier pack I've tried is heavy, and this one's the same. 7 Lbs is a big pack. But this one is as comfortable as it gets for me. The adjustability let me get a perfect fit, and that makes longer hikes with the kid quite pleasant. The straps are padded, but not so much as to be bulky. The kid carrier section is easily adjusted to the quick growth of a toddler. And its relatively well padded so when they inevitably fall asleep it's on a padded surface.
We now use this instead of a stroller at events and things where getting around with a stroller would be a pain. Its got enough storage to keep what usually goes in the diaper bag, and it collapses down relatively small when its not in use.
My only real complaint is the hydration setup. You really have to fish the bladder down into the "anti gravity" back system, and then your water gets hot quicker than in other packs because its literally touching your back when the bladder is full. Thats not enough to make me wish for a different pack, just something I'd like to see change on future versions.
