EXODUS CF 57L | 3500 CI

Backpacker Magazine: Best UL Pack
WEIGHT: 15 oz | 370 gm
CAPACITY: 57L | 3500 Ci
LOAD RANGE: 20-25 lbs

We took our Backpacker Magazine awarding winning Exodus 57L – the lightest full-size, full-featured, frameless pack made – and we made an even lighter Cuben Fiber version!

Th Exodus CF is a professional level frameless backpack designed for serious lightweight backpackers. It’s a thru-hikers dream come true!


• Cuben version is seam taped inside for better water resistance. Keys areas are also liquid seam sealed. It’s not as water resistant as a dedicated River Style Dry Bag but does a good job of rain protection. Use of stuff sacks inside encouraged,  but there is no need for an additional pack liner or rain cover.
• Cuben is a little stiffer material making is a bit easier to load.
• Cuben version uses a roll top design integrated into the side compression system for simplicity.
• Cuben version does not have the bottom volume reduction loops, hydration ports or inside hang loops
• Cuben version is the same size and constructed as the Dyneema version
• Cuben fabric does not absorb water: The pack has slightly fewer straps, so it will weight 1- 3 oz less when wet in prolonged rains.
• The White colored Cuben Fiber makes the interior brighter to help locate gear in low-light.
• We love the awesome white color!
• Cuben version uses a double-thick lower back panel in Cuben + Dyneema X for abrasion resistance.
• Cuben version uses the same EVA padded shoulder and hip belts.
• Cuben version weighs slightly less


• One of the most supportive and cushioned hip belts in any sub 20 oz frameless pack. Padded SuperWick Mesh lined waist belt wings with 1.5″ webbing and buckle. Adjusts from about 28″ to 45″.
• S-shaped, comfort shoulder straps: 3.5″ wide X .8″ thick, SuperWick Mesh lined with full length highest quality 1/2″ thick EVA foam padding. Our shoulder straps are thicker and wider than most all other lightweight packs. Shoulder strap lower pack attachments are isolated from the hip belt for move comfort…yes; comfort is all in the details.
• Curved, SuperWick Mesh lined ergonomically shaped shoulder straps with full-length daisy chains to mount water bottle and accessory pouches. These are very comfortable shoulder straps and are super tough.
• Curved Side Panels: A slight curve from the waist to the shoulders moves the load closer to the upper back for more comfort. This also creates a slightly larger main compartment higher in the pack that helps load control by moving the heavier and higher packed gear higher to reduces shoulder stress.
• Hybrid Mesh/Dyneema X Side and Rear Pockets. The leading edge of the side pockets are Dyneema X to prevent snagging when moving through the bush. The lower 5″ of the rear pocket is Dyneema X to prevent abrasion from sharp contents or butt sliding accidents. The 4 oz sq yd open-hole non-stretch drains fast to allow contents to dry more quickly than a tight stretch mesh or solid fabric. Dyneema X elastic top sleeves for long term Durability and elastic replacement. Slanted side mesh pockets are deep enough for a 2L Platy. Pocket top bungee sleeves of Dyneema X for long term durability. Pocket adjusts by pulling the bungee closed through the cord lock. Many lower priced packs simply bind over the top of the raw mesh with regular garment type elastic that loses it’s stretch in a few years and doesn’t stretch in deep cold weather.
• 4oz sq yd Open-hole non-stretch mesh. Stronger than stretch mesh that is twice the weight. Easy to field repair, does not absorb water and drains fast. Dyneema X elastic top sleeves for long term Durability and easy bungee elastic replacement.
• Dual ice axe/trek pole loops.
• The main bag is large enough for a solo bear canister vertical or horizontal depending on how you pack your sleep pad.
• Removable multi-position “Awesome Sternum Strap” with Black Whistle-Lock Buckle 0.5 oz (not included in base pack weight)
• Side V compression straps with full strength buckles.
• Long shoulder straps terminate in hand/finger rest loops.


• 10″ of black 1/8″ bungee cord
• 2 mini cord clips and 3 cord locks

• Torso lengths on MLD packs are measured from the bottom of the pack below the waist belt wings to the point where the shoulder straps attach to the pack.
• 95% of MLD packs users do best to go by our height guidelines
• Different pack makers and outdoor stores measure for torso length differently AND frameless pack are measured and fit differently than fully framed packs with large hip belts. DO NOT go to your local outdoor store (REI etc…) and “get pack fitted” and then select a size/length based on that measurement; it will be wrong!
• Use our height guide! If you need help deciding the right size – Please feel free to give us a call. (Please don’t order multiple sizes as a guess!)
• Test Fit You Pack Indoors after Receiving it – We are happy to exchange for different size or refund new/unused packs.

• If In Doubt – SIZE UP!

Q: Why doesn’t the Cuben version weigh a lot less than the Dyneema X version?
A: The amount of fabric in the main pack body is only about 40% of the total pack weight. Mesh pockets, straps, 3D mesh on straps, shoulder & hip belt strap foam, and hardware accounts for the other 60%. The Cuben we use is fairly tough and weighs close to the same as the Dyneema X and so the pack total weight is about the same. We changed a few features but keep most for total function, strength, and comfort.

Q: Is the Light Weight Suspension option available on the Cuben Packs?
A: Nope! For loads under 25 lbs suspension is not needed.
