Jam 50L Pack (Unisex)

3-liter hydration compatible

3-liter hydration compatible

Use this pack with your favorite 3-liter hydration bladder.



The comPACKtor™ system makes your pack far more versatile by enabling you to reduce your pack's volume through the use of two fixed compression anchor clips and adjustable side compression straps. With the comPACKtor™ system engaged, your pack is instantly transformed from a lightweight multi-day carrying system into a day-tripper or peak-bagger with smaller profile and volume.



Dyneema® The fabric of choice for our standard-setting UltraLite Series packs, our exclusive Dyneema® Gridstop weave combines 100% nylon base yarn with Dyneema fibers to deliver the strongest, lightest, performance pack fabric ever produced. Dyneema fibers have a strength-to-weight ratio that is 15 times better than high tensile steel, making this fabric incredibly difficult to tear.
  • Double-Wishbone™ hipbelt with quick-access zippered stretch pockets

  • High-void meshes on back panel and shoulder harness
  • ComPACKtor™ system reduces volume via easy to use anchor/strap system

Great quality, poor color choices
I ordered this pack and the quality was exactly what I expected. Lightweight, versatile, and strong. I had to return it though unfortunately. Just gotta ask, you call it a "unisex" pack, what's with the horrible colors? The only real acceptable color (for men) is the "grease" color. The other's are either female pack colors, or just outright obnoxious. Bring back the older style and color schemes. Love the 2010 packs.

I just finished the Georgia section of the Appalachian Trail this past week with this pack and I cant stop talking about how awesome this pack is. The trip lasted 7 days and my pack weight was around 23 pounds with food and water. The entire time I was hiking I had to keep reminding myself that there was a pack on my back. The hip belt straps on this pack have to be one of the best designs I have seen on a pack. This is the first pack I have owned that I was able to put all the weight on my hips, which is one of the reasons the pack is so comfortable. If you are on the fence about this bag dont be, pick one up! You will love it!

Nice pack, ugly blue
Love the pack, but boy is the blue awful. Really wish these packs came in colors that blended in with nature.

6 years, 2.5 years permanent travel and going
I've had the Jam² 50l for 6 years now. Have been using it for trekking, via ferratas and mountaineering before taking it on my round the world trip 2.5 years ago. I'm still traveling and so is my Jam². It went around the world twice already. Best product ever! The only downside? It's very hard to get in Germany, so I can't even recommend it to my friends at home )-;

All that and less
I have had this pack for over a year now, and used for everything from backpacking to train travel to beach trips. It is amazingly light weight and functional, and is my go to back for just about everything. It is incredibly to switch to a pack that just carries your stuff and disappears otherwise, rather than lugging an extra 6 pounds everywhere you go.
