Epic 14.4

The pack does what its supposed to — keep the weight low, off the shoulders and on the hips. My only observation is as I carry a fair amount of weight, the pack will ride up my back, regardless of how tight I adjust the the hip belt. Aside from that, I really like the pack.

I really like these packs. A lot.

I bought the 6.2 in February. Then I bought the 10.3, thinking I needed the extra space, but it wasn't really enough to make a difference for me so I returned that (super easy process by the way). Then, I went on a 30+mile bender and felt a bit under prepared. So, I bought the big dog 14.4 and it's been great. The extra size is minimally noticeable for me, but the extra space is fantastic. I think the pockets on this and the 10.3 are easier to use than the 6.2. I find that after unzipping the pockets on the 6.2, I miss the zipped pocket and wind up wrestling with the elasicated outer pocket on that model. These are just the zippered version and it's truly easy to get stuff in and out of while riding. In my opinion, you can't go wrong with any of the Arctos offerings. They are high quality, well designed pieces of gear. Almost all of my riding is in the high desert of the Southwestern United States and the breathability has been great for me. Even as our temps begin to climb into the unreasonable zone. For me, the Papa bear and Baby bear versions are just right for everything I want to get into.

Love the Arctos Epic 14L pack

After putting the Arctos Epic 14.4 through its paces on some MTB trails in the Black Hills of South Dakota, this pack has earned my trust. It nails the fundamentals and then adds a few thoughtful touches that make it stand out from other hydration packs in this size class. The defining feature of the Epic 14.4 is how it rides. Instead of sitting high on the shoulders like a traditional hydration pack, it settles low on the back — right where a hip pack would normally sit. Paired with the shoulder and hip straps working together, the pack locks into place and doesn't shift, bounce, or wander during a ride. That low center of gravity makes a real difference over a long day in the saddle. The 4L bladder is the headline number, and it earns its keep. For all-day rides where refill stops are scarce or non-existent, having that much water on board is a genuine game-changer. No more rationing sips or cutting routes short because the reservoir ran dry. The hip strap side pockets are where the Epic 14.4 really separates itself. The side pockets are sized generously enough to swallow an iPhone 17 Pro Max — and that's not a small phone. Being able to stash and retrieve a large phone without taking the pack off is exactly the kind of detail that matters when you're riding. The zippers open and close cleanly with one hand, so grabbing the phone for a photo or a quick check is effortless. The heavy-duty YKK zippers throughout the pack are buttery smooth. No catching, no resistance, no fighting with the pulls — they just glide. YKK is the gold standard for a reason, and Arctos clearly didn't cut corners here. This is the kind of hardware that holds up over years of abuse. Low-riding stability, massive hydration capacity, phone-friendly side pockets, and premium zippers. The Arctos Epic 14.4 is a five-star pack for serious all-day riders who want a hydration pack that actually thinks through how it gets used on the trail.
