Description

Common features to all packs:

• Functional 4-point compression cords that fully cover the pack sides from top to bottom, allowing to significantly reduce pack volume when needed (28L packs have a 3-point compression system due to size).
• 
Big stretchy spandex/nylon front mesh stores a lot of gear.
• Comfortable 11mm (7/16”) thick and 7cm (2.75″) wide shoulder straps, padded with EVA-foam and 3D spacer mesh.
• The attachment points of the shoulder straps to the back panel are reinforced with double layer of fabric, when using DCF2.92 or xPac x21rc, for extra durability and tear resistance.
Chest straps with loops for lightweight hardware-free connection to the daisy chain.
• Drainage hole at each side pocket
Taped seams (only when choosing DCF as pack material). A pack liner is suggested with xPac fabric in rainy conditions.
• Bonfus attention to detail and love into making gear.

 

The following section provides an overview of the different options to choose from and their approximate weights. Be aware that with all the options available, final weight might vary a bit from what theoretically calculated. We try our best to provide as accurate measurements as possible and stay on the conservative side, hopefully your pack will weight less!

Note: “right” and “left” sides always refer to the pack when worn, or, equivalently, the right and left when looking at the front mesh pocket.

Pack volume, fabric and size

Pack volume
Weight: starting weight with preselected standard options (excluding removable hip belt): 28L (240g), 38L (265g), 48L (300g).
We offer our backpacks in three different sizes.
•  The 28 L pack (22 L internal volume, 6 L external pockets) is perfect for SUL trips or overnight trips with lightweight gear. Average circumference: 78cm. Unrolled height: 65cm
•  The 38 L pack (30 L internal volume, 8 L external pockets) is perfect for overnight trips or multi-day trips with lightweight gear. Average fcircumference: 85cm. Unrolled height: 75cm
•  The 48 L pack is perfect if you are getting into lightweight gear and want your first frameless pack, or it can be used on expeditions with many days worth of food and lightweight gear. Average circumference: 92cm. Unrolled height: 83cm

Pack fabric
Weight: xPac x21rc adds +45g (28L),+50g (38L), +55g (48L). DCF5.0 adds +52g (28L), +60g (38L), +70g (48L).
Note: DCF packs come fully seam sealed with DCF-tape.
We know, choosing between DCF and xpac Fabrics is very hard and it really boils down to personal preferences. Please visit our “materials” page for more information about the technical properties of each fabric. To summarize, we can say that xPac x21rc fabric offers high abrasion resistance due to a face fabric made up with 210D nylon. Also, in our experience, xPac fabrics maintain a “cleaner look” longer compared to DCF fabrics that are more prone to show folds and wrinkles. DCF 2.92 fabric, on the other hand, allows to reduce your pack weight even more and at the same time provide a more waterproof solution, thanks to taped seams. With DCF5.0, you get a rugged pack with taped seams at a small additional weight compared to xPac x21rc.
In our opinion, xPac x21rc fabric offer the greatest value for the cost, while DCF fabrics will give you the top of light weight performance.

Bottom fabric
Weight: +5g
This option is only available when choosing DCF 2.92 as main pack fabric. By using DCF 5.0 as the main pack fabric you can improve durability in the area of the pack that is most exposed to wear and Abrasion. DCF 5.0 also allows to keep the seams of the pack waterproof as it can be seam sealed just as DCF 2.92.

Torso size
Choosing the correct torso size will make your pack sit more comfortably and adapt to your back. For guidance about how to measure your torso length please refer to our guide (coming soon). Please note that the 28L pack will come in one standard size only, due to its limited dimensions. Generally, most people will have a torso length in the range 48-52cm.

 

Roll top closure system

Roll top strap
Weight: Y-style strap adds +5g.
The simple single strap is lighter, more minimalistic and holds the top of the pack secure and compressed. Most items will be hold in place just fine under a single strap. For particularly wide and slippery items, Y-style straps might be a better choice.

Roll top closure
Velcro has faster closing/opening. Snaps are more minimalistic and will not snag on clothes or other objects. We do however use soft velcro that reduces snagging. Both systems will work well, it is all about preferences!

 

External pockets

Side pockets
Weight: each mesh pocket will add about +10g
Fabric pockets are lower and perfect for fitting water bottles that can be extracted on the go without removing the pack. We use double layer of elastic webbing at the top hem to snugly hold your gear.
Mesh pockets are taller and have higher capacity. Standard mesh is lighter, has incredible 4-way stretch and will work fine on trails. Stronger mesh has less stretch but is more abrasion resistant. The bottom area of the mesh pocket is reinforced with DCF/xPac (depending on what you choose as main pack fabric) for increased abrasion resistance (see pictures).

Bottom pocket
Weight: the bottom pocket adds about +20-23g
The bottom pocket is a handy feature to quickly pull out or store gear, snacks or clothes To be used on the go. This option also helps protecting the fabric at the bottom of the pack. As a standard we use our stronger mash in our bottom pockets.

Mesh fabric
Weight: the stronger mesh adds about +15g for the front mesh pocket, and +8g for each side mesh pocket chosen.
We use stretchy spandex/nylon pack meshes. Our standard mesh has an incredible 4-way stretch. We suggest it for most applications unless you expect a lot of off-trail wandering through bushes or abrasive rocks. The heavier duty option has roughly 2x the abrasion resistance and has less stretch and is heavier than our standard mesh, but will resist to more abrasion and wear.

 

Shoulder straps and hipbelt

Shoulder straps pockets
Weight: +10g each
With this option you can choose to add sewn-in stretchy mesh shoulder pockets. These pockets are perfect to store objects like a GPS, a phone, snacks, water bottle or other gear that you want to have at close reach. Under the mesh pocket you will still have the daisychain to attach your sternum strap. We think that these pockets are extremely handy to have so we suggest to have a shoulder pocket on at least one shoulder strap. Our favorite combination is to have a stretchy mesh shoulder pocket on the left shoulder strap and a removable shoulder pouch mounted on the daisychain of the right shoulder strap. Removable shoulder pouches can be added in the section “add on accessories”.

Hip belt
Weight: removable webbing hipbelt (+35g), removable padded hipbelt (+60g), sewn-in hipbelt wings (+60g)
With this option you can either choose to use no hip belt at all, a simple but extremely effective webbing belt, a removable padded hip belt, or sewn-in hipbelt wings (like the ones in our Saccus 48L). The last option is only available when choosing a pack volume of 48 L as the pack needs to be taller to accommodate this option.
We do suggest to use at least the webbing hip belt. Even if not padded, the webbing hip belt helps stabilizing the pack on your back and transfer a part of the load to your hips. Removable padded hipbelts provide more comfort at an additional weight. Sewn-in padded hipbelt wings are the most stable and comfortable option if you want to carry heavier loads, but cannot be removed.

 

Others

Back panel pad support system
Weight: +10g
This option allows you to attach a foam pad to the back panel of the pack to increase comfort and ventilation. It is an ultralight solution that is very versatile as it can be removed completely if needed.

Front pocket shock cords
Weight: +10g
This options allows you to add a “grid” of shock cords on top of the front mesh pocket. This system can be useful to secure bulky objects like foam mats, Or to hang wet clothes to dry in the sun. It adds very little weight and is completely removable if you wish to reduce weight when necessary.

Ice axe loops
Weight: +5g
Ice axe loops allow you to attach ice exes or other similar gear on the front of your pack. It is made up of a grosgrain webbing at the bottom and an elastic loop towards the top of the front mesh pocket.
