The Gregory Optic 58L Backpack features an ultralight design with the support to comfortably carry heavier loads. A super strong yet lightweight frame made of 7001 aluminum ensures your cargo is stable when packed to the brim. This frame efficiently transfers weight to the padded lumbar support and hipbelt, and side compression straps help manage your pack size to prevent shifting and keep the weight centered on your back. A cushy, ventilated shoulder harness pairs with the breezy backpanel to promote airflow and prevent sweat build-up. An internal sleeve with a hose port integrates with your hydration bladder, and conveniently angled stretch mesh pockets on each side can hold onto your water bottles. There's a pocket in the lid to keep smaller items organized and easily accessible, but you can detach the lid to further shed weight if you'd like.

Rated 4 out of 5 by from Great pack with some opportunities for improvement I really love everything about this pack – it’s adjustable, lightweight and hugs your hips – except the durability of the plastic hardware is questionable. On the second day of backpacking (with only 28lb total pack weight), the plastic on the synch strap that goes over the top opening of the pack broke while synching it down. I called Gregory and they said to send it back to the retailer which I did and ended up buying another one. I think Gregory went too far in trying to get this pack (size large) down to 2.52 lbs. I would give this pack 5 stars if the hardware was more durable – everything about it is wonderful except for the cheap plastic.

Rated 5 out of 5 by from Great lightweight bag This bag carries easy. I would recommend it to anyone who believes the best feature is less weight. I'm 5' 9" 175 and a medium was a good fit.

Rated 2 out of 5 by from Lumbar Pad is Irritating The lumbar pad has a seam running along the bottom where a piece of heavy duty nylon is sewn. I could not feel the seam while wearing the pack with just a sleeping bag inside for filler, but when I put 15 lbs of gear inside (pack is rated for 35 lbs), I could feel it rubbing against the small of my back. It was irritating enough that I felt chafing would develop with continued use. I returned the pack, which is a shame because I really liked the rest of it. If the lumbar pad gets redesigned and that seam removed, I would definitely revisit purchasing.

Rated 5 out of 5 by from Great option for lightweight backpacking I think this is a great pack for multiple day, lightweight backpacking. I bought it for a section hike of the AT with my son. I already owned the Osprey Exos which is very similar to this pack. However, the Optic exceeds the Exos in a number of areas. First the hip belt is much more comfortable and make the load more easy to carry. The hip pockets are large enough to actually hold a phone and other essentials. And it includes a rain cover which cost me an additional $30 for the Exos. The downside is as a lightweight pack I don't see this pack lasting as long as some of my other heavier and sturdier packs. Yet, if you are looking for an affordable lightweight option the Optic is a good choice.

Rated 5 out of 5 by from Ultralight and comfortable I bought this for a JMT hike, which I haven't done. However, the bag performed really well during a 3-day test-run. It's lightweight, comfortable, and does everything I want in a hiking backpack.

Rated 4 out of 5 by from Light weight very comfortable After conducting significant research looking for a pack that was around 60L I bought the Optic 58L. I could only find a couple of reviews on this pack and one mentioned the buckles were cheap and broke easily. I have a Stout 35L, which I really love and is built with the highest quality. So I took a chance and made the buy. The pack arrived and when I unpacked it, I was amazed at how light it felt, especially for a full framed pack of this size. I loaded it with all my gear for an overnight trip and tried it on for fit. I am 6' and weight about 220 lbs. I am fairly broad chest and shoulders. I bought the large and it fits very comfortably. It is a little snug through the chest but not to the point of feeling uncomfortable. Likely it is just a matter of proper weight distribution and adjustments. I unpacked my gear and repacked it to try and move the weight around a bit for comfort. When I cinched up the strap that goes over the top of the main pack, the buckle busted into pieces. I knew exactly what the other reviewer was talking about. This was only the third time I had cinched the strap down so I was more than a little disappointed in this. The buckle is made of a thin brittle plastic and should never have been put on a strap that will have any pressure on it at all. I did not want to replace the buckle with the same thing so I looked for an alternative. I found the perfect fix at my local Sportsman's Warehouse, see photos. The new hook styled system was easy to put on and is very strong and secure. This is what Gregory should have used in the first place. So no that my pack was fixed, to the trail I went. My pack load was about 40lbs, which is the pack's max load rating. The pack handled it great and it felt comfortable the entire time. Great ventilation, great comfort and all the feature worked perfectly. Overall, I am very pleased with the pack and would have gladly given it 5 stars had it not been for the cheap buckle issue. The buckle is my only complaint.

Rated 3 out of 5 by from I wish it fit better. The design of this bag is fantastic, love the color, and good capacity, but in the end the thing that matters the most is comfort. The majority of the pressure was actually below the lower back pad. Where the seam meets the pad it just pushed too much in my lower back so I had to return it. I wanted this bag to work so bad. Love the bag, please try again with the padding and ergonomics.

Rated 5 out of 5 by from Exos watch out ! Gregory is here Got this new optic 58 from Moosejaw during their 20% off discount sale, I own and have used the Exos 58 (2016) for several Mountain overnight hikes. Both packs I have are medium and fit same/ feel same size wise. This Gregory really caught my eye ! (Photos- grey Gregory Optic 58 left, black/ green Osprey Exos 58 right ) Gregory is very well known for a really comfortable suspension and fit. I will try to sort out some key differences you might want to consider. Gregory Optic vs Osprey Exos....... Main belt buckle is small.......Exos is much larger. That might be a durability issue long term. Many important straps on the Gregory are only 10 mm wide.....many of the Exos are 15 mm wide. The Gregory shoulder straps are thinner and firmer but wider than Exos, Exos straps aren’t as wide but are thicker and cushier. The Gregory shoulder straps are much more curved/ contoured than Exos and the sternum strap height is easily adjusted on the Optic. Exos sternum strap height can be adjusted but must be completely removed to do so. The Exos has a sternum strap whistle and one of the straps is elastic, the Gregory one is a solid stiff strap , and the buckle has NO whistle. Gregory does NOT have shoulder strap pouches like Exos, Exos strap pouches are stretchy and can hold snack bars and small items. Gregory hip belt pouches/ pockets can fit an I-phone 10/X but it’s snug, the Exos cannot - even with its small stretchy portion. Gregory hipbelt pouches are more water resistant than Exos because there is no “stretchy” portion. Gregory hipbelt tightens more around the top portion of of the hipbelt, the Exos is more in the middle. Gregory has a lower back/ Lumbar pad, the Exos does NOT. Both Optic and Exos have suspended back “trampoline” frames, the Exos is a solid mesh screen top to bottom. The Gregory has some “softer” vertical lines in its mesh trampoline screen, and a lower back lumbar pad. The Exos has a much much bigger air gap from your back to the main pack, The Gregory main pack is a lot closer to the “trampoline” suspension. This could be good or bad... that gap puts the Exos load weight out a little further away from your center of gravity, However with the Gregory the pack load is closer to your center of gravity giving you better balance when having to lean slightly backwards. I feel though that the down side to the Gregory Optics back frame, with the closeness, the lumbar pad, and the vertical mini cushion stripes is that it is going to ride much hotter and not be as cool on your back as the Exos. If you hike in the cold anyway this probably won’t matter much, but for hot summer days it might mean a lot. The Gregory and Exos both have a removable top lid/ brain pouch, both with 2 zippered sections. inside section of Exos is mesh, Optic is solid fabric. The big main compartment top opening flat stretched width on the Gregory is 18.5” at the top, the Exos is 21.5” The Gregory has a top compression strap outside the main compartment, the Exos has a thicker heavier red one that is internal. The Gregory comes WITH a pack cover, AND a separate top compartment flap cover you can use, after removing the top pouch/ brain. Even though the Exos does have a removable top brain pouch, the flap cover used in place of this is already sewn into the pack and is NOT REMOVABLE. I’ve never understood why Osprey did this. I’m also told they (Osprey) removed the hipbelt pockets on the 2018 Exos model.... BIG mistake in my opinion, Maybe they’re counting on selling after market accessory pouches ? ....Who knows. This Gregory optic 58 will probably overtake Osprey Exos 2018 sales just on that I think. Maybe hip belt pockets aren’t as important to that many hikers but I have yet to find one that said ..... “Man I wish this pack of mine didn’t have belt pockets” lol. The Gregory main pack compartment has a more inward tapered “Beatle back” shaped bottom, the Exos has a wider more square bottom with slightly less mesh exposed to the wear area where you would set the pack on the ground. The mesh outer pouches and the main beaver tail pouch are almost identical on both the Gregory and Exos , as well as the all the petite compression straps throughout. The Gregory Optic has 2 small attachment loops on the bottom of main compartment. The Exos has 2 but they are more up on the main compartment rather than directly on th bottom. Both packs have several lashing points and loops. Some of the Exos loops have reflective highlights, I haven’t noticed any reflective features on the Gregory as of yet. The zipper pulls on the Gregory Optic are larger than the Osprey Exos as well as the lifting loop strap at the top of the pack for picking it up. (This might be important if your wearing gloves) Some reviewers at other sites complain the top brain pouch on the Optic has too short of front straps (behind your head with pack on) because they would like it to be able to extend up more. They Exos has NO straps in this area, only toggle hooks to attach or remove it. I haven’t mentioned anything about storing ice axes or trekking poles because I don’t use these items. Or a pack cover (I use a full poncho) Both Gregory Optic and Osprey Exos are hydration bladder compatible and weigh about the same at 2lbs 10oz (minus the pack cover) The materials on both packs feel the same to me thickness wise. (The stretchy material on the Optic kind of changes tone/ color when you stretch it because of the printed pattern ) As for Gregory’s “first run” at a really light weight pack I think the Optic 58 is very nice !

- + Size Guide

Gregory Men's Packs

Gregory backpacking packs are available in a size range. Please check the PRODUCT FEATURES and / or SPECIFICATIONS for the torso range measurements of each size of a pack. The steps below are a guide for measuring your torso size.

The hipbelts on Gregory backpacking packs are adjustable to fit a range of sizes. A simple rule of thumb is that the ideal distance between the ends of the hipbelt pads after tightening should be 3 to 5 inches. However, the most important criteria are that the hipbelt wraps clear over the side of your body and that it rests 1 inch above your iliac crest. This allows proper load transfer to your skeletal structure, which maximizes comfort and minimizes energy expenditure.


HOW to MEASURE TORSO SIZE
1. Put your chin to your chest and feel for the big bone protruding on your neck at the top of your spine. That's the C7 vertebra.

2. Feel your hip bone, the top part of this is your iliac crest. Find the spot on your back that is level with the top of this crest.

3. Have someone measure the distance between these two points, following the contours of your spine.
