UPDATE:
We are currently transitioning our hydration reservoirs to Hydrapak® from our previous supplier, TSI. During this rolling change, the reservoir included depends on the pack color selected:
- Black: Ships with TSI reservoir assembly (pictured).
- Sand: Ships with Hydrapak Compact 3L reservoir assembly (3L version of the 2L reservoir the Swift 6.2 has)
Features
- 10 liters of overall storage, 3 liter hydration capacity from included 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 hydration reservoir with quick-disconnect and large opening makes for easy cleaning, adding ice, etc.
- 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.
- Soft, protected, tech pocket for fragile/small items.
- Velcro webbing keepers to minimize flappy excess material.
- Covered by our lifetime True North guarantee.
Fit
Our packs typically fit folks between 5'4" and 6'5". Near or below 5'4", particularly if you have a smaller frame, you may 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 mid-2026.

Love it. Did a 25 mile ride with it, fit everything I needed, plenty of water, stayed put, didn’t get too hot, zero complaints.
The pack holds everything and stays in place as promised.
Thanks for the well thought out design!
Honestly, this is a baller pack. I've only worn it on 1 ride so far as the weather here in Utah has been a bit fickle. Good fit even though I'm in the Clydesdale category of riders. My only sad is that I ordered one that isn't large enough for me i.e. capacity. Idon't know what I was thinking. The 10.3 is the perfect water vessel size but man... the 14 would have just been a better pack for me and my gear. Such is in this world. We make mistakes and we move on. At least I'll be moving on in style. Truly sweet bag!!
Very well designed and built! Once you strap this pack on it disappears even full loaded. Does not bounce aroumd while you ride. Most comfortable pack Ive ever worn! I will never use anything else.
The pack is well built zippers are great. I am 5'4"and it turned out to be too big. It felt find wearing it around the house. But on the bike just a little bit too big. Not sure I like all the weight in one spot. It's like having a tire around my waist. I wish I could return it but had to use it to get it dialed in. Will be trying to sell it.
Sorry to hear that Sean. For these first production runs, we had to aim for a size range that would fit as many of our potential customers as possible, which regrettably meant some folks are outside the size range. Now that we're growing, we've got the demand to meet our factory's minimum order quantities for smaller sizes, and we have smaller size samples being made and tested right now. Should be out later this year.
I'll send you an email - I can help you out with the pack. Thanks for giving us a shot!
