Question: What are the orange long pockets in the main compartment used for?
Document: I was looking to upgrade from my Manta 25 to a larger pack. The Mantas have a deep curve which makes pulling things out of the main compartment (especially larger items) a bit of a chore. The pack itself is great. It's comfortable to wear, well-balanced (I'm 6'0), and there are tons of pockets for storage. And, as always, Osprey quality is second to none. So why'd I return it? The color. Osprey describes their red as &#34;radiant&#34; - well, there's nothing radiant about it.
I've had the Manta 30 for 2.5 years. The Manta 36 was the pack that replaced it. I purchased the Manta 30 at the time because they were on clearance as the 36 just hit the shelves. I tried both and their fit and design were darn close to the same with the 36 having a slight larger main compartment.Hiking:** This is my go-to bag for 24hr or less hikes in the spring / summer / fall. ** The frame suspension is excellent and really excels in the summer heat.
There&#8217;s also a handy key loop in the smaller zipper compartment. And a specific section for delicate goods (like sunglasses or a phone) with softer fabric. Plus slips for bicycle tools in the main compartment, and a side zipper that allows you to get to your buried gear without having to empty the entire pack.This is definitely a great buy if you&#8217;re looking for a high quality hydration pack to take hiking, fishing, biking, etc. It&#8217;s a great all around pack.
That's 1800 cu. in. for the previous model versus 2197 in the new. The smaller size went from 26L to 34L, a major increase. Though I only checked out the old versions in store, I can say that the main compartment and the electronics pocket both seem quite a bit larger.The second major difference is the weight of the bag. Even though quite a bit of storage space was gained, the weight of the bag actually went down! The M/L bag in the previous model weight 3 lbs 2 oz, which is quite heavy for a day pack.
Personally, I like lots of pockets to sort and stash stuff, but I&#8217;m just going on day hikes. This pack is just big enough for ultralight overnight backpacking trips though, so I can see where it would be tough to fit overnight gear into the broken up storage areas.It&#8217;s really all the little touches that make this such a great pack. There a waterproof rain cover stored in the bottom in a hidden compartment that I have fortunately never had to use. Though its unfortunately a bright red color and doesn&#8217;t really match the pack.
I was tossed up between getting a Manta or Stratos bag as a new day pack. I like the organization and separate hydration bladder compartment in the Manta series but I liked the sturdier harness of the Stratos series. I ended up going with the Manta because its main use will be for trail running and as a &#34;get home bag&#34;; the elastic chest strap and waist strap make it more suited for running and activities and the many compartments makes it easy to organize your stuff.A note on sizing; I am 5' 9&#34; and 155lbs and when I was in the store trying these on while they were empty the M/L felt like a good fit and the S/M felt like I was wearing a little kid's backpack.
There a number of other nice outside pockets, including the shove it pocket (which is really just the space between the two main compartments), the front stretch pocket (a good size), and the side stretch pockets. The side stretch pockets are nice but the lower side compression straps do cover them a bit.Finally, the stow as you go pole straps are a really cool idea. What impressed me so much about them is where the poles end up sitting on your body when stowed. I can walk normally and the poles stay tucked to the inside of my body, away from my arms.
I bought this bag for day to day commutes and to take on day hikes. I wear it around the city with about 15 pounds of stuff (books, laptop, etc). I love the weight distribution with this bag, and i hardly feel it on my shoulders. Its got pretty good storage space, and it collapses pretty small so it could probably be used only as a hydration unit if you scrunch it all down. I have done some hiking (nothing too long), the bag performed as i expected and was comfortable the whole time and the hydration system works fine too.
I purchased this pack mostly for my daily commute to and from work. It's about 10 miles each way, so I needed a pack that had plenty of room for clothes and lunch, but also provided a hydration system, as the ride home is usually pretty hot in the summer. I did quite a bit of research on packs before settling on this one and I'm glad that I did. The 3L hydration system is more than enough for my daily commute, but is also perfect for long mountain bike rides on the weekend.
So much better than my previous backpacks.5) Made in USA - not a lot of products left that can say that!=> All around one of the best purchases I've made in a long time.Wanted to add one more item: I am frequently packing my 17" Dell work laptop with no problems. I don't have the problem that the other reviewer refers to when describing that the "suspended back makes it impossible to tote around the laptop with confidence", but I am also not constantly putting it on the ground with the PC inside...
