Description

Siskin 12L Backpack

The Osprey Siskin 12L Backpack has one goal: to keep you riding in comfort. The Atilon foam framesheet gives the load structure so the weight can be evenly distributed across your body, while the AirScape backpanel provides excellent airflow between your back and the pack to keep you cool. Osprey included its Hydraulics LT 2.5L Reservoir to ensure you can carry plenty of water with you on your ride, and that your bladder will interface perfectly with the pack. The U-zip main compartment grants you access to internal organization options with plenty of space to store your tools, layer, snacks, and other gear, while hip belt pockets and a sunglass pocket keep small items where you can easily find them. Dual side compression straps eliminate excess space to streamline your pack, or double as extra straps to help the LidLock attachment secure a full face helmet.
  • Low-profile pack for riding in comfort
  • AirScape backpanel maximizes ventilation
  • Atilon foam framesheet provides structure for the load
  • BioStretch harness conforms to your shoulders
  • Included reservoir stores up to 2.5 liters of water
  • LidLock attachment secures a standard helmet
  • Side compression straps double as full-face helmet straps
  • Light attachment point increases low-light visibility

How to Measure:
For best results, have someone take the measurement for you.
Torso:
Start at the iliac crest (the top of your hipbone that you can feel like a shelf on the side of your body). From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down. Make sure to keep your back straight while having the measurement taken.
Hip:
Measure around your hips, at your iliac crest, not your waist.

I previously have been using an older CamelBak Lobo, which works well but has minimal gear storage space, and I needed something bigger for road trips or longer rides. This pack is of excellent quality, you can tell it was designed specifically for mountain bikers. It has enough room for any tools I need to carry, plus holds an extra layer, snacks and my camera gear. The magnetic clip holds well; I've never had the bite valve break loose yet. I run a gimbal and GoPro on my chest while biking, and I was concerned about the magnets being too close to the gimbal and messing up the electronics inside it, but the sternum strap sits way higher up on the chest than I thought it would, so this isn't an issue at all. A little pricey compared to larger, non-biking specific packs from Osprey, but it's worth it, as this pack sits tight on your back, doesn't get in the way, and doesn't move around much unless the trails get really rowdy.

Great pack

Familiarity:
I've used it several times

A very good mtb pack, I’ve used this a lot and I love it. It has plenty of pockets for my bike tools and other stuff. I enjoy the helmet clip for hiking around and stuff. The hydration bladder is easy to get in and out and fill. Pack isn’t the most comfortable I have but not bad. All n all pretty solid mtb pack
