Everything It Said It Would Be
I really like the backpack. I have been on three trips with it now and it performs well. It is light, comfortable, easy to use and has kept the rain out all three times.

Perfect Lightweight Pack
I can't believe how light this pack is, I bit the bullet and paid the $$$ and don't regret it one bit! Its really easy to think i'm not paying that for a pack!!! Now being the owner of the 2400 Junction i can definitely see why you pay more for less!

Finally, The Pack of all Trades
From the moment I stumbled on this product to the second I arrived home from my last trip, my mind was blown. All I can say, Junction 2400, is what even was my outdoor life before I met you? I can’t wait to take you on bigger trips!

My new favorite

I own number of packs 25 to 70 liter, I purchased the Junction 40 this year for a Kilimanjaro climb in December.

I pretty much subjected this pack to a wide range of conditions, torrential rain, sleet, snow and it performed perfectly. The mesh pockets were very useful for drying things out and it was very handy to able to see and access the contents of the mesh areas

I utilized several size pods to maximize the interior space. The roll top was also useful for quick access to rain gear, puffy etc. All in all a very versatile work horse!

Just right

Well made, compact and it fits me just right, I think. I haven't had a chance to take it for a spin yet but everything fits. I'll be interested to see whether it rides as nicely as my Arc .
