Great sized pack but my zipper is starting to stick at the corners and I haven't gotten any dirt/debris on the zipper itself (this is on a road bike and only after about 6 rides)...

I have used this hydration pack on and off for 2 years now.  But it wasn't until this year that I really started to use it a lot because of an extended illness through 2014.  Overall, I have been pleased with it except for today when I was out for a bike ride.  About a mile into the ride, the sternum strap detached from the right side "slide" for lack of a better word.  It is a piece of plastic tubing inside of the fabric.  The sternum strap pieces can slide up and down and provide nice adjustment and comfort.  However, upon stopping and examining what happened I found that the plastic tube inside of the fabric was crushed and in pieces and had torn through the fabric.  I rolled it between my fingers and the plastic continued to break apart.  I was able to crush the tubing still remaining inside of the fabric quite easily.  But only on the right side.  The left side still seems solid.  I managed to get the strap reattached and was able to complete my ride without it detaching again.  This is not a problem that will cause me to stop using the pack but it is annoying because I'll have to permanently attach the strap to the pack by sewing it on.  While I'm at it, I'll sew the left side to match.  I will no longer be able to slide the sternum strap up and down for comfort but it is a small loss in functionality.  Other than that issue, it has been a good hydration pack and I have been using it almost daily for the past two months.  I like the large opening of the bladder because I can toss some ice cubes in to keep my water cool for long rides.  I would give it recommendation as a small but good hydration pack.  It has been great for my long bike ride.  I hardly know it is there until I need it.

Just what I needed-not that breathable however, but it's great for shorter rides, lightweight, visible and keeps me dry. Update: fiappointed that zipper broke and jsmmed  3rd time using

This pack is amazing, with one exception. There is a soft nylon used in a few places (insides of the straps and the top of the pack in a small area behind the handle). The soft material comes apart at the seams of course and just should not have been used. That said, I still LOVE this pack, I just plan to replace that material when it becomes a real issue. That material has already come apart at the seems but has not proven to be a problem yet.

Nice pack but within 2 days of school the zipper broke

Light pack. Lots of space. Lots of pockets. Easy zipper closures. Like the back ventilation. Like that I can size the pack. Seams and stitching held up on a tough 17 mile trek in Colorado.
Con: shoulder padding pooped out after one hike. Pack was about 35-40 lbs. shoulder pads are flat already. Bummed the foam didn't hold up. Good pack for the price except for shoulder pads. 3 stars cause tons of pockets don't make up for blistered shoulders.

Bought this backpack for my 7 year old. She loves it! So far it's holding up pretty well. My only complaint is the small mesh pouches on either side are already starting to rip after 3 months of use.

The backpack is great my main issue was the zippers it comes with these leather straps that aren't really secure and they usually come off and once you loose them it becomes so annoying to open your backpack

I'v probably had this back pack for about a year and a half and used it to go to school everyday it can carry all my text books and binders and has held up well. The only down side is that the inside zipper never worked from the moment i got it and unfortunately didn't have enough time to return it seance school was starting the next day. So far the only wear are tare after all this time has been that the silver ring where you tie it move the right strap is coming off(i normally only hold it on my right shoulder). Altogether i would definitely buy this again its super cute and gets the job done.

Let me start off by saying that this is a very nice pack for the money. It is durable and functional. The bag expands quite a bit once you loosen up the compression straps and can easily fit plenty of gear inside. The zippers also seem to be very durable and that can be a typical weakness on bags like this, this one doesn't seem to have that problem. The bag is water resistant and has plenty of molle webbing on all sides for anything you might need to add on. There are four compartments. Two large and two small. The zipper on the main compartment goes all the way down the pack so the entire thing can be opened like a suit case. This helps for quick access and to fit more. The only thing I wish I had from this pack was a little more space. If all your looking for is a typical day pack this will work great for you, but I tend to need a bag for a little bit longer than that. If your like me I would recommend the miltech 36 liter pack. They are in the same price range as well. If your just looking for a light bag that you only need about a day or a little over a day out of this pack is one of the best for the money. One thing that I did find, which probably won't matter to most people, but this bag is great to use if you ride a motorcycle. In this case the size is it's friend. The bag can hold whatever you need when riding but is small enough that it does not constrict your movement while riding. The shoulder straps are comfortable and the waist strap helps to keep the pack secure on your back and keep if from moving and it does just that.

Pros:
Affordable
Comfortable
Very Expandable
Durable Construction
Lightweight

Cons:
May Be Slightly Smaller Than You Think

Bought as Christmas gift (at his direction) for my son. His 1st snowboarding weekend (this one) with it, zipper breaks on one of the pack's pockets and he loses a lot of items. I'll keep you updated on how Osprey handles the replacement process. Low stars for now because of the breakage but the back pack does look good and seemed very sturdy. My son was excited to have it.

Pack would be great but the zippers are a pain...they get snagged and don't work smoothly despite my efforts to use pencil lead, etc to try to smoothen the track.

I am female 5'10 about 128lbs... was a little worried about the fit of this bag. But the Ergo fit seems to work perfect for my body. Was very pleased. Love all the extra pockets and storage compartments. Great bag for a great price!

Update: I got the pack and loved everything about it. However; finally got to take the pack on a weekend expedition and my opinion has unfortunetly changed. A few of my zippers have broke (not sure if it was just a manufacturing defect), very uncomfortable, the compartments on the front belt were more of a hindrance than useful, also if you have a petetite waist opt for a different pack. It's still loose around my hips even tightened at the tightest setting, which gave me blisters. Looks like I'm still in the market for a comfortable, and reliable pack. :(

After a couple months of use mainly mountain biking around 2-3 hour rides I like this hydration pack, it does the job. Bladder is good but the mouthpiece tends to drip some and it also fell off( i replaced with similar walmart brand mouthpiece).

This is more of a short hike or ride kinda pack not half day trip or greater due to storage capacity for items you may need while biking. What i have been able to stuff in there is a Bike tube, cell phone, wallet, keys and a granola bar,  cant really stuff a whole lot of items (which its not intended for). Its decent though. Haven't tried adding a pouch with the MOLLE system but will do next to increase capacity.

There is no padding on straps but they do NOT dig in to your shoulders even with full bladder and items which i was worried about before purchase so thats a plus.

Too many bells and whistles?  Unfortunately, each bell and whistle comes with a possible failure.  In this case, there are a lot of pockets with zippers, some of which have to break. I took the backpack fully loaded on two day hikes to test out balance, fit, etc.  All was good so I loaded it up for it's first multi day wilderness trip and headed out.  Second morning, I noticed that the zipper on the outside of the brain is opening behind the zipper pull.  In other words, the zipper won't close ... just goes back and forth leaving it open both directions.  Oh well, there is another zipper'd pocket inside the brain, so I just transfered my "easy to get to stuff" there and finished my trip.  On the positive side, the adjustable fit worked well, the hip belt was comfortable, and the shoulder straps felt good with 30 lbs (once I got the adjustable back set up correctly).  In summary, good pack for the $$, however, I wouldn't want to set out on a lengthy thru hike with it.

Got this when it was on sale and when I needed a better back pack for my daily commute by bike. This backpack fits a lot of stuff, I particulary love the extendability of the main compartment to fit a full set of cloths plus lunch and some smaller items. As others have noted, the side pocket for the laptop is great in theory, but it has some flaws in daily life. I indeed keep it unzipped (usually without anything in it, but I can see that if you're a little scatter brained, a laptop can fall out easily).
What I don't like about the side pocket is the fact that pushing the laptop in and pulling it out, it always scratches the laptop (just a tiny bit, but I still feel for it). Otherwise I love the backpack, but can only give it 4 stars for it's bikeability. Due to the shape, it's kinda hard to look over your shoulders - there's always the pack in the way when looking if someone else is passing you. I wish the front pocket would be divided so I can keep my keys and phone separate without worrying it getting scratched or having to open to main compartment, but these are all minor issues.

Review for Helly Hansen Duffel Bag 2 30-Liter Black.

Disclosure: This has been my main travel bag for almost a year now and it's seen two weeks in Australia and New Zealand, multiple flights back and forth between California and Texas, and many weekend trips. I have not used the previous version of the bag.

3.75 stars
Pros:
- Backpack straps are great and tuck away nicely (albeit just a little difficult)
- Most straps are fairly rugged feeling
- One large main compartment with an inner mesh pocket and one outer zippered pocket (perfect for my Kindle)
- Very water resistant
- Looks sharp

Cons:
- Velcro stitching on the handle came undone during my trip abroad
- Beefier thread and stitching would have been appreciated
- Beefier zippers would have been nice
- Could be a touch lighter

Overall I really like this bag and have no plans to replace it. The 30 liter size was great for a minimalist two week trip and perfect for any shorter ones. The shape of the bag lends to fitting in almost any space in planes or cars. Unfortunately I really wish the quality of the stitching was up to par, because then it'd be a 4.5 star bag. However, a few dabs of super glue and the Velcro patch is now actually more secure than it was. I did have this bag stuffed to the max at 25 pounds when it happened. Under normal use I could see it lasting much longer.
