Osprey Siskin 12 Mens Bike Hydration Backpack With Hydraulics Reservoir, Obsidian Black

This is our fourth Osprey pack in 12 months - it joins an Aether 70, Hikelite 26 and a little Kobi 20 (my daughters); good value for money at this price (although not sure why black is cheaper?!) its another great product from the brand. The pack appears bigger than the Camelbak MULE it replaced despite apparently being smaller and its a lot more comfortable. The bladder comes with no quick release hose valve which is a shame but works well with the baffles helping to stop the water from sloshing too much. Do make sure you fold the top forwards though to close it - I accidentally tried several times the other way and the slide just kept getting stuck. Inside the space is well thought out and even a full bladder doesnt intrude on pack space; unlike the MULE. It sits nicely on my back and the zips are all decent quality; I would prefer some form of waterproofing on the main zip as it has no cover but so far its stayed dry. The side pockets are useful too - I plan on using this for trail runs too and my iPhone Xr just about fits so I can take photos on longer run without removing the pack. So a decent pack, the usual Osprey quality and well thought out.
