Deuter attack 20 - Deuter Attack 20 L Backpack

Overall I love this pack. The attack 20 replaced a CameBak HAWK. I wanted another HAWG but after examining the new version I moved on to Deuter. The only negative I can say about this pack is that it's heavy. Even when the crash pad removed the biking weight weanies will not like this one. Now on to the good stuff. The Attack has well padded and formed shoulder straps as well padded waist belt. This is the most comfortable hydration pack I've ever worn. It's a cozy and rides great. Plenty of adjustment in the shoulder straps and has load straps as well. For me organization was a big reason I went with the Attack. There is a large compartment on the outside of the pack that has plenty of room for my bike tools I ride with. Among the tools is a set of tire levers, patch kit, extra tube, chain tool, multi tool, and CO2 inflator with extra CO2's. Under this pocket is a zippered pocket that contains the helmet stash pouch. Besides using it for your helmet I plan to use it to hold wet hiking clothes. It's plenty large enough to hold an extra fleece for hiking. Below the helmet pouch it the rain fly. The fly is bright yellow and easily covers the whole pack. The is a very large zippered and lined pocket for sunglasses and your wallet will fit in there as well. On the right side of the bag is vertical zippered pocket for a cell phone. For me it's a bit awkward to reach.I use the sunglass pocket for my phone. The main compartment is very large. It's huge actually. For hiking it will easily hold my first aid kit, rain gear, food, gloves and hat. With the old HAWG I had to use extra straps to hold my hiking gear on the outside. Everything now fits inside but there are compression straps on the pack that you can lash down extra layers if needed. Granted the Attack is 200 cubic inches larger than the HAWG but it stowes gear like it's twice that size. As much as I like the main compartment the water bladder compartmet is my favorite. The zipper is large and zips down to the bottom of the pack which allows easy access. It's a breeze to load and unload the bladder. You can use any 3L bladder. I'm still using my old CamelBak bladder and it fits well. You can route the hose out the top to either side unlike the HAWG which only goes out the right side.Overall this is a well thought out pack and will server me for both mountain biking and day hiking.
