Rated 5 out of 5 by from Great Pack, Worth the Price! I debated for entirely to long about buying either the Baltoro 75 or 65 and landed on the 65 to save a little weight. I am 145, 5'7" and the small seems to fit perfectly! I have used this pack in up north trips in Michigan & recently through the Grand Canyon and it was great. I love the suspension system & the lack of back pain when using this :) I ended up going with the 65 @ a small because it is a nice blend of attempting to be light-weight & having the available space for longer hikes & the top lid detaches for longer trips which adds a few liters of space. Highly recommend!

Rated 5 out of 5 by from All around winner I have been through many backpacks on my quest to find the boltoro 65. I even had owned the old version of the boltoro and ended up selling it to find something lighter. I bought packs from osprey, granite gear, arcteryx and they all left me wanting the old Gregory back. When Gregory revamped this pack for 2015 I was instantly sold. They had dropped the weight of the pack without sacrificing the thing I loved most about it-the suspension. This pack is extremely comfortable and built like a tank. The fabrics are durable and have a high quality feel to them. Only gripe aboutthepackisthe waterproof pocket doesn't fit an iPhone 6 with case very easily. Buy it, you will not regret.

Rated 4 out of 5 by from Awesome Pack! I bought this pack with going lighter in mind. I own a Baltoro 75 that is only a few years old and I love it but my thinking was that a smaller pack would force me to pack a bit less. I took this pack on an over nighter to Savage Gulf in Tennessee and still over packed but it hardly mattered! I went from a medium suspension to a small suspension and I'm still fiddling with the adjustments but it handled the weight well and was comfortable. The only downside that I can see is that the waist belt and the belt of my pants sometimes pinched my stomach. I believe that I can adjust the suspension for a better fit and all will be perfect! Gregory is the Cadillac of packs and this new model is another home run!

Rated 5 out of 5 by from Tons of features I chose this pack over the AG Osprey. The pivoting hip belt is a must. It moves with your body. The weight is perfectly distributed and supported. Love the front, top and bottom access. The removable day pack is genius. You can put the gear you want to bring into the tent into it. So many pockets and storage places! The waterproof hip pocket is nice. Wish it was bigger. Great place for your wallet. Wish there was more mesh, but not at the expense of support. The best pack available in my opinion.

Rated 4 out of 5 by from Comfortable for Heavier Loads. Flawed Day-Pack. Pretty much everything you've heard/read about this pack is true. It's one of the best backpacks for loads over 40 pounds. While the full-foam back-panel and hip-belt don't offer much ventilation, they afford excellent support and comport. As others have mentioned, the major flow with the Baltoro is it's day-pack/hydration pack. It's basically a flimsy hydration pack with thin backpacking straps. Gregory should just emulate other and make a removable top-lid that converts into a day-pack. Sure, many others do it, but that's because it's practical. If Gregory would address the day-pack issue and create one that's more useful, the Baltoro would be about as close to perfection as any backpack can be.

Rated 3 out of 5 by from Great pack but! This is my forth Gregory pack. I like their craftsmanship and fit. This is no different except for the following. The pack has an integrated pocket on its right side near the hip belt. This pocket is to hold a water container, very handy. However, the bottom portion uses mesh? This lasted about 4 hikes before it wore through. This needs to be a much more durable material. I have an old chalk bag that I will modify in an attempt to fix this.

Rated 5 out of 5 by from Comfort hauler! I bought the Baltoro 65, 75 and Scout 45, 65. I returned everything but the Baltoro 75. I really wanted to like the Scout but the Baltoro is worth each and every one of 1lb 3 oz ounces more that it weights. Please see my review of the Scout which is an unfortunate miss in Gregory's lineup. The instant I put on the Baltoro the comfort and perfect fit was immediately apparent. I tested it first with 40lb of Kitty Litter in each pack then I loaded 5 days worth of gear and food into it. My decision was made before even taking the pack on the trail. I could not believe I had 45lbs on my back. It felt effortless and the transfer between hip and shoulder straps (as I tightened one and loosened the other) was seamless. Comparison of Stout Vs. Baltoro The main pieces organization between the two packs is roughly the same (one large compartment, lid, brain, etc) Baltoro : Adjustable shoulder straps (a must in my opinion), adjustable load straps, wider more padded shoulder straps, accommodating my chest width (185lb 5'11), weight rides effortlessly. Bottomline: everything you could want and more. With 35lb+ loads I could not think of a better pack. Stout: 1lb 3oz lighter, constructed well (as to be expected from Gregory), unfortunately this pack just did NOT fit well for me. The shoulder strap connection to the bag were not adjustable (they are stitched to the bag) and they pinched in on my chest and armpits. It almost felt like I was wearing a woman's pack. The shoulder strap was also less padded but the padding should have worked for loads of up to and around 40-45lbs if the fit was better. The chest strap was not long enough to accommodate my moderate chest width (see picture). Bottomline: check the fit before you commit. This is not meant for everyone. I would have loved to save 1lb 3oz with the Stout but the differences are unmistakable. I know cutting weight requires compromises but I expected better fit and a few basic adjustments from Gregory.

Rated 5 out of 5 by from Great Pack Overall happy with my purchase. Took this pack out for 30 miles round trip hike. great suspension system carried my load with ease and barely notice the 40lbs on my back. This pack comes with a daypack that was very useful for me when I was fetching water from a spring. I was able to get this pack through the airport without issues and plan to take this backpacking overseas.

I am looking to purchase the baltoro 65.  This will be my first Gregory pack. After measuring my torso "many times" I am right around 18". Gregory suggests I should opt for the small.  I'm seriously debating between the small and medium.  I am 5'-10"

Asked by: The Golden Cheese
At your height go up, definitely not down. I don't know why they tell people this repeatedly, but if you go down in size, your load lifter straps will be below the top of your shoulders and you'll never be comfortable with a load on a long hike. "personal experience"

I am looking to do a thru hike when I retire from the military in a few years. I will have a dog with me for most of the hike and might have to carry some extra food for him that he can't carry himself. Would you recommend the 65L or 75L? Thank you

Asked by: NOLA Boy
Based on the information you provided, we recommend the Baltoro 75 Pack for your thru hike.

I see note of different hip-belt sizes.  Am I able to purchase a custom hip-belt at the time of ordering or do I have to get the standard belt size and then purchase a replacement later?

Asked by: Zier
We do carry the hipbelts for the new Baltoro 65 pack. You can order the size that you need along with the pack. Once you switch out the hipbelts, you can return the belt that came off of the pack back to your local store for a refund.

Am I able to bungee cord anything to the outside, because I dont see any attachment points?

Asked by: RTFhiker
The Baltoro 65 Pack has shockcords on the outside of the pack to attach ice axes or trekking poles. You can attach your gear to those shockcords and loops or you could attach a bungee to the attachment points.
