Why We Like The Siskin 8L Backpack

The Osprey Packs Siskin 8L Backpack offers just enough room for your water and a few absolute essentials when you're hitting the trails for a day of mountain biking or hiking. The included 2.5L reservoir keeps you hydrated while the u-zip main compartment opens wide so you can stuff in a spare tube, repair tools, snacks, and an extra layer. The front of the pack has a LidLock attachment point for your standard size helmet, or, if you've got your full face helmet, the side compression straps expand so it fits comfortably. The Siskin's mesh covered backpanel and supportive shoulder straps make carrying the pack comfortable and easy so you can focus on the trail ahead.

Smells Awful

I've used it several times
Size Bought:
5' 10"

I purchased this backpack in November, but didn't use it until February of this year and have now used it a total of three times. I bought this pack primarily for road cycling. Immediately after my first 90 minute ride with this pack, the mesh on the back and on the straps smelled awful. That made me think that the pack had been used before it was sent to me (not likely because the original tags were attached) OR the material is just inherently susceptible to odor production. My body and clothes were clean prior to the ride, so it's not like I was pushing this piece of gear beyond expected performance. I thoroughly cleaned the pack according to manufacturer's instructions, which removed the odor, but it returned immediately after my next 20-mile ride. Again, I gave it a thorough cleaning, sprayed with Lysol, and cleaned again, but it happened once again and I'm no longer willing to deal with this piece of crap. Unfortunately, the 30-day return window is long past. Just warning potential buyers to avoid this pack if you perspire to a moderate degree. Very disappointed in Osprey.
