Why We Like The Katmai 65L Backpack

Great Bag

This pack has all the features I was looking for. Flexible side pockets, big belt pockets and multiple areas to access the pack.

Worked well on my first trip, very comfortable for my taller frame. Packed a good amount of goodies into it

Solid overnight pack

The frame and well padded hip belt make carrying weight very comfortable even for extended durations. The side access on the bag is extremely useful for accessing smaller items on the trail without having to empty the bag. After a year of consistent use, the bag has held up well without any real signs of wear. My only complaint is that the bag doesn’t come with a rain cover as many bags in the same price range do.

Really durable, no damage or rips from extensive bushwhacking. Straps are all easy to use and work well. Definitely recommend. Difficult to use a non Gregory brand hydration pack with the provided loop, had to improvise an adapter for my Camelbak bladder.

Katmai 65 m/l

I’m about a month away from using it on trail but carrying it around the house it’s very comfortable and much more sturdy than my cheap pack I previously had. I’m excited to get out and put it to the test. Delivery was quick and I’ve only heard great things about these packs. Hope they are all true!

Excellent backpack

I took this on an 18 mile trip along the south olympic peninsula of Washington state. This thing holds a lot of gear and is very comfortable. I am a bigger person and it fit really well (even the hip belt). I definitely recommend Gregory products. This is great for your first real technical backpack. Definitely watch the fitting videos on the Gregory website. I also recommend purchasing the 2 or 3 liter water bladder from Gregory.

Awesome bag

The side zipper is a very convenient feature. I could dig stuff out of my bag without having to take everything out. The walking stick holders are very convenient. There are enough compartments in the bag to be able to organize your stuff and I found the bag itself to be extremely comfortable. Overall I would recommend if you need extra room and a comfortable bag.

Great backpacking pack

It was a great pack while doing an overnighter (could use a smaller pack for overnight trips, but I plan to use the pack for longer trips as well). Lots of pockets and zippers for easy accessibility. Staps felt secure and comfortable. Would reccomend to others
