Review on 40L Lightweight Waterproof Hiking Backpack With Rain Cover For Outdoor Sports, Travel Daypack For Cycling Skiing Camping Climbing (Black) by Jeff Clites

Pros:- Inexpensive- Shoulder pads are comfortable.- Back doesn't get too hot and sweaty while hiking.Cons:- The straps that hang down from your arms, the ones you pull on to tighten up the shoulder straps (I'm not sure what to call these), they keep slipping. I have to keep tugging on those straps to tighten the adjustment as I'm hiking because it comes loose quickly. I've tied the slack across my chest to hold it in place somewhat, but it's uncomfortable. This is my biggest issue with this bag.- The nubs at the end of the adjustable loop for holding trekking poles to the bag popped off of mine (see photos).- The main compartment of the bag is just one big space, and the zipper to open the main compartment goes down all the way around the back nearly to the bottom. I've had a hard time accessing things because they're at the bottom, then I have a hard time zipping the bag back up because the zipper has slipped down all the way down both sides. I have to lay the bag on the ground and pull both zippers up to secure it again. This is especially a problem when hiking in mixed weather as I'm tucking layers away during a hike. (See photo for fully opened main compartment.)- The shape and length of the bag makes it easy for certain items to become literal lumps against your back. The part of the back that goes against the back molds itself to whatever is in the bag, so I have to carefully pack it so that I don't end up with an uncomfortably lumpy bag against my back.Other Notes:- I bought a 3 liter water reservoir for this bag, and it fits perfectly. There doesn't appear to be any place specifically for holding the hose down against the shoulder pad, but I've found that tucking the bite valve under/through the reflective loop on the shoulder pad works just fine (see photos).- I haven't tried the rain cover, so I can't speak to that.- I'm 5'2' and the bottom of the bag reaches the top of my butt. That hasn't bothered me, but it might bother someone else around my height.
