It's a KeeperReview by CB
I purchased one of the last 2015 versions of the pack and couldn't be happier. My first excursion was a quick overnighter up the side of a mountain. To cover 6.5 miles and an elevation gain of 3,800 feet I wanted a light pack and the Kumo worked out perfectly. Light weight and narrow I was able to scramble without constantly having my elbows hitting the pack.

The fit and finish of the pack was great. When I received it I immediately turned it inside out to check the sewing. With other packs I've had to seal the edges of the fabric to prevent the seams from fraying before even using the pack. There were no exposed fabric edges or loose treads to take care of. All the edges were either folded over or had grosgrain ribbon sealing the seams. This is not something you normally read about in the product descriptions but goes to the quality of the pack.

With a base weight of 9lbs and a total pack weight of 18lbs the pack was very comfortable. Not sure I would put much more than 20lbs in the pack unless you have strong shoulders. Never had any hot spots and the wide straps kept the weight dispersed on my shoulders.

At first I wasn't to sure of the lower chest strap. But after trying it out while crossing a scree field I found that it worked great to pull the pack tight to my back and prevented it from moving. Very similar to some of the running vests I have tried. Now it has me thinking about adding clips to the shoulder straps on my other packs.

I may have to experiment with the back padding, I used the standard sit pad and found my back getting hot. This is not unique to this pack and I often have to find a solution for more airflow. Fortunately it's easy to remove and replace with other options.

Admittedly it was only one trip but I don't see myself putting the Kumo on a gear swap list any time in the future. It's a keeper. (Posted on 7/12/16)
People let me tell you 'bout my best friendReview by mjmaze
What can I say about this pack? It's awesome! I used it for 500 miles of a thru-hike and only switched to something else to test a different setup. This pack proved to be rugged, light, dependable, and capable of carrying everything I need for an entire week. My base weight is 12 lbs and I used a ProLite Plus (size small) folded up as the back cushioning. with less than 20 lbs total weight, this pack carried very nicely and proved to be comfortable. The oversize pockets on each side make water bottle retrieval easy and the mesh pocket on the outside holds tons of daily use items. Even when stuffed tight it never showed signs of weakness. For a pack that weighs in around 16 oz., it is surprisingly durable. I own the 2015 version and I couldn't be happier. This pack will definitely be something I use for years to come.

Love this packReview by Gram Daddy
So I broke down and bought a Kumo in order to retire my old blue Murmur. I've been in denial but it's time. What made it easy was trying the Kumo I bought for one of my sons. Super comfortable, same capacity as my Murmur but much more durable. Love the over the top closure with it's pocket. Yes, I love the Murmur. Yes, I know the Kumo is almost twice (cringe) the weight of 'old blue'. Will likely buy a new Murmur soon, but the Kumo is simply a great platform for rougher conditions. Plan to take it when I start section hiking the AZT this Fall. This makes four Kumos in the family now. Get one! Or two, or three..... (Posted on 5/13/16)
2016 KumoReview by Andy
I ordered an older model Kumo on clearance and was pleasantly surprised when I opened the package to find a brand new updated red-trimmed 2016 version. Super cool. I was able to load it up and use it immediately for a week long, non-backpacking vacation trip.

First thing I noticed was how well this pack is made. Its tightened up.. no extra fabric is used, nothing is saggy, therefore it sits like a dream. Apparently this is a bit heavier than the older version. The hipbelt is removable and I have yet to use it, didn't need it for my trip.

Overall I'm extremely happy with my new pack and my wife even commented on how nice a pack it is. Really looking forward to loading it up for a true multi-day backpacking trip this summer. I believe Gossamer Gear is cutting edge in the pack business, love my Mariposa and now my Kumo. Thanks GG! (Posted on 4/19/16)
Perfect pack for a weekendReview by Sierrahiker
I've taken the Kumo on around 8-10 trips ranging from 1 to 3 nights in the Sierras in the Tahoe National Forest. It's the perfect little pack for these trips as you can fit everything you need in it and nothing that you don't.

As another reviewer mentioned, if your baseweight is above 10 pounds than you probably want to be looking at the Gorilla for the extra support. On most of my trips I carried between 15-20 pounds fully packed and it carried great.

I've used it with and without the hipbelt with pockets and didn't notice a huge difference in how it carried but did appreciate the pockets for easy access. That is one of the two things I'd change about the pack, love to see it with an integrated hipbelt and I'm also not a huge fan of the over the top closure but that is just a personal preference. But how awesome is it that GG's latest pack is exactly what I would change about the Kumo! Have a Pilgrim coming in the mail as we speak as I've always preferred roll top closure and it has the integrated hipbelt as well! Perfection in my mind.

I've used 5 different of GG's packs in my backpacking and hiking journeys and can say that they are on par or superior in quality to all of the other cottage and big box brands out there.

Awesome Pack! Will not disappoint!Review by Zach
Just took this pack on a 3 day trip through the Smokies on the AT, this is an awesome pack! The pack is the perfect size, I had enough room for my gear and food for 3 days, and had much more room to spare!

The shoulder straps are very comfortable, as is the hipbelt with pockets. The sit light pad also came in handy on many occasions. I even used it as a pillow by rolling it up and putting it in a small stuff sack. I found the pack perfectly comfortable with this pad as the frame.

I did spray the pack with camp dry waterproof spray before my hike. Although it rained the whole first day on the trail, the inside of the pack stayed dry, and even the hip belt pockets stayed dry. The exterior of the material did wick some moisture, but I did not see any moisture penetrate through the interior coating. (This was more of a misty slow rain and not downpour though) I would still recommend packing your gear in a pack liner or dry sacks.

The hipbelt material does get a little slippery when wet, and I had to re-adjust the hip belt often while hiking because it would loosen up, but it really is not that much of an inconvenience.

I would recommend this pack to anyone, It is very comfortable, reasonably sized, light weight, and has excellent functionality. (Posted on 8/15/15)
My favorite pack refinedReview by Allgood
After a few seasons with the old Kumo, I was a bit hesitant if the new pack would live up to it's predecessor.....Not only did it do that it exceeded my expectations. The new kumo retains all of the old packs size, charm and design values with new and improved updates to this classic frameless pack.

The first new feature is the redesigned shoulder straps, the old kumo had nice wide straps which I loved but they always were a bit light on the padding. the new shoulder straps are extra cushy-and the foam material seems to move sweat well away from your body while retaining it's comfort.

The other major improvement to the pack is the new robic fabric. While I loved the dynema I find that the robic fabric has a higher level of water resistance and will not wet out as fast as the dynema. The robic so far has held up well to abrasions in the field and I find it has less stretch than the dynema did.

Other suggestions from a long time Kumo user:
1. Get the hipbelt with pockets it will make accessing your sundries like lip balm that much easier while on trail.

2. Do not overload this pack-if you have a base weight of 10lbs or less you will over this pack, but get it;s toal weight above 25lbs and you may be complaining about the feel

3. I use the trose tri fold pad in place of the sit light that comes with the pack. It gives you a bit more padding and structure-plu sit only adds a smidgen of weight

4. Get out and enjoy a hike with it.

That last piece of advice is my best one. This pack is such a joy to carry that once you realize you can fit all your gear in here you will be happily skipping down the trail with a pack that is light, compact and an Ultra Lighters dream come true.
