Features
- Fits roughly 5'5" - 6'5". See fit section below for details.
- 10 liters of overall storage, 3 liter hydration capacity from included Hydrapak bladder.
- Low-profile lumbar design keeps the weight on your hips (and off your shoulders) and doesn't hit the back of your helmet while riding steep terrain or jumps.
- Industry-largest side pockets for easy one-handed access to ride essentials (phone, food, multi-tool, etc.) without removing the pack.
- Dual-purpose waist cinch secures the pack to your body and compresses pack contents for bounce-free descents.
- 3/4-zip large main compartment with separate area for hydration bladder makes stuffing oversize loads into the bottom of the pack easier.
- Top-zip secondary compartment for tool storage with divider and key clip. Large enough for high capacity MTB pumps and tubes.
- Low, wide, easy-fill Hydrapak hydration reservoir with quick-disconnect makes for easy cleaning, adding ice, etc.
- Magnet clip for securing bite valve to sternum strap.
- Minimalistic lash points on bottom for extra storage if needed.
- Oversized, durable YKK zippers and 210D nylon construction meant to handle all the dirt, sweat, sun and neglect you can throw at it. Made in a top-shelf factory that also makes outdoor gear for first responders.
-
Helmet storage using shoulder straps.
- 1.5" wide waist strap for less pressure on your stomach.

Fit
Our packs typically fit folks between 5'5" and 6'5". If you're near 5'5" and on the slim side (under 150lb), you will probably run out of adjustment room on the shoulder straps. Users slightly over 6'5" may be ok, depending on other dimensions (chest/torso size, etc.). We are happy to send you a free return label if it doesn't fit.
If you're close to the ends of our adjustment range, we have detailed fit videos available to give you the best shot of our packs fitting you.
Note: We are actively developing smaller strap sizes to accommodate those below 5'4", launching late-2026.

Great concept
I’ve only used the pack once. The one time was absolutely wonderful!
It feels great it’s the best hydro pack on the market! I’m very pleased with my purchase.
Love my Artcos pack! Carries more than my old 12ltr backpack, much better air flow when it's hot and very comfortable. Easy access for on the trail needs.
Bought this to get more water carrying capability as well as moving the weight off my back. I also needed more space under the straps so my pack could work with my Alpinestars airbag. I ride pretty aggressively on my KTM 890 Adv R and this pack is going to be perfect. Holds my tools, snacks, plenty of water, everything I need for a full day of riding.
Saw a FB ad for this hydration pack and I was in need of a new pack so I pulled the trigger on it. I took it for a trial run today and it did not disappoint. I got the medium-sized pack and it held everything I needed for a ride plus has a 3L reservoir . I like that the side pocket can hold my phone for easy access allowing g me to not have it in my pocket. On the climbs, it felt like it wasn't there and on the downhill, it stayed where it should and was very secure. If you are on the fence, just buy it and send it!
