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 UltraGrid fabric, for extra tear resistance.
Chest straps with loops for lightweight hardware-free connection to the daisy chain.
• Drainage hole at each side pocket
Taped seams (with Ultra200X as pack material).
• 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 and combinations available, final weight might vary a bit from what theoretically calculated. We try our best to provide as accurate measurements as possible.

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  (excluding hip belt option): 28L (350g/11.8oz), 38L (365g/12.2oz), 48L (380g/14.3oz).
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 circumference: 85cm. Unrolled height: 73cm
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: 81cm

Pack fabric
Weight: included in the starting weight.
Ultra200x packs come fully seam sealed with DCF-tape.
Ultra 200 X Black or White (130gsm | 3.85oz/sqy) – Probably the most advanced pack fabric on the market. It features woven 200D UHMWPE fibers. At a slight weight increase compared to DCF2.92, the Ultra 200 fabric has 3x higher tear strength, 3x higher UHMWPE fibers content, 7x the abrasion resistance. The backing of the fabric is a .75mil recycled polyester film with X-grid, that makes the fabric extremely waterproof.

Bottom fabric
Weight: included in the starting weight.
Ultra400X improves durability in the area of the pack that is most exposed to wear and abrasion.

UltraGrid Fabric for shoulder straps, side pockets and hipbelt
Weight: included in the starting weight.
UltraGrid is an amazing fabric with high abrasion resistance, perfect for use as a side pocket, shoulder straps and hipbelt material. This fabric is less stiff than DCF/Ultra/Xpac materials, so it better adapts to the curves of the shoulder straps/hipbelt and it is more suited as a side pocket fabric. It has also exceptionally high stitch holding strength.

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 below. 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 46-54cm (18″-22″).

Roll top closure system

Roll top strap
Weight: Y-style strap adds +10g/0.35oz.
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.

 

External pockets

Side pockets
Weight: each mesh pocket will add about +15g / 0.53oz
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.
Side mesh pockets are taller and have higher capacity. Standard stretch mesh in nylon/spandex is used. It has good stretch and durability, as we use a slightly thicker variety than most other manufacturers for increased reliability. The bottom area of the side mesh pocket is reinforced with UltraGrid Black for increased abrasion resistance. UltraStretch is not used for side pockets due to its limited stretch.

Bottom pocket
Weight: no bottom pocket reduces weight by about 20g / 0.8oz
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. Standard nylon/spandex or UltraStretch fabrics can be chosen.

Front pocket and bottom pocket stretch fabric
Weight: UltraStretch saves abuot 7g / 0.25oz for the front mesh pocket and 4g / 0.14oz for the bottom pocket.
Standard nylon/spandex or UltraStretch fabrics can be chosen. We use a slightly thicker variety of nylon/spandex stretch fabric compared to other manufacturers, so durability is good. UltraStretch has a little more tear resistance thanks to its ripstop grid in Ultra fibers and slightly less weight, though it stretches less than the standard nylon/spandex fabric so pocket capacity is reduced.

Shoulder straps and hipbelt

Shoulder Strap Style
Weight: Vest Style Straps add (to be decided)
Standard shoulder straps have a gentle S form and are padded throughout their whole length. It is the standard design used in our Framus, Iterus and Saccus backpacks.
The vest style straps (available only for 28L and 38L Altus packs) are optimized for stability when fastpacking and running. It is the same vest strap used in our Fastus 23L pack. Padded until the shoulders, it is composed of breathable meshed for freedom of movement, stretch, and breathability and features 5 mesh pockets to store two soft flasks (or bottles), snacks and items needed on the go.

Shoulder straps pockets
Weight: One mesh pocket included in the starting weight. Adding a second mesh pocket +12g / 0.4oz
With this option (available only for standard shoulder straps, not for vest straps) 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 / 1.2oz), sewn-in hipbelt wings (+85g / 3oz)
With this option you can either choose between a simple but extremely effective webbing 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.
Removable padded hipbelts can be added in the “add-on” section and provide more comfort at a limited 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 / 0.35oz
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 / 0.35oz
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 / 0.17oz each
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.
