Nicely updated

I bought this recently and am quite pleased. It is very similar to my Trailblazer 30 from around 4 years ago (the zipper started to give way, it was very will used). I like that there is now a top zippered pocket for smaller items like keys, phone, glass case, gels, etc. The older pack only had an interior mesh pocket next to the hydration sleeve. There is also a smaller zippered pocket on the back of the pack in this version, as well as a small bungee system for poles (?), though I used this to secure my larger water bottle. My only complaint would be that taller water bottles aren't fully supported in the 2 side mesh pockets, though as I mentioned above I used the bungee cord system to secure my taller steel bottle.

My favorite backpack for hiking and running

I used the red one so much (2 years) and the color is washed out now. It still works fine but I just wanted to have new one in different color. I will probably use both of them for a while for the right occasions. I can't seem to find anything like this in different brand. Highly recommended!

Bought this bag a while ago, super satisfied with it. Perfect to go on small hikes and to use a a day to day bag!

Side pockets too small

Would be perfect all-rounder for daily life and hiking but the side pockets are too shallow for all but the smallest water bottles; so the only option for easy hydration on the move is a bladder, which is not ideal for everyone (taste, fragility, monitoring water levels,...).

Perfect pack for daily commute

Purchased for my daily bike ride to work. Fits everything g needed and more - change of clothes, lunch and laptop. Lots of easy access pockets and very comfortable. Good back venting as well. A few reviews mentioned an issue with the key holder in the top pocket - have not had this issue.

Great rucksack

I've been using this for my daily commute to work which is a 5 mile trail run .the rucksack is big enough for everything I need for my day packed lunch ,waterproof jacket and extra clothing. It has a couple of handy zipped pockets in addition to the main zipped compartments.

Could be better

I wish it had hydration pockets on the shoulder straps and a bungee on the front for more storage.

I walked the whole Camino using this as a daypack and couldn’t have been happier. Super comfortable, fit my water reservoir nicely, convenient little side belt pockets for my chapstick and sunscreen. Highly recommend.

Amazing bag, small changes needed

I absolutely love this running rucksack. It is spacious and I really like the clip features- as a woman, running bags are usually too big, but this is great because of the adjustable straps. This morning a chocolate pudding split in my bag and it exploded everywhere- this bag's waterproof features are brilliant. All I needed to do was wipe it up with a wet cloth and it was basically brand new. I feel less stressed running to work with food in my bag knowing that it will be fine if anything splits or spills. One small critique is that the top section of the bag is tricky to open or close because the zip gets caught on the small red thing in the bag. That part of the bag needs to be designed better. Overall, love this bag and really impressed with it.
