With the arrangement of the external pockets, the Junction easily handles any terrain and conditions. HMG relies on a simple, proven design and the best materials. The backpack is constructed from super durable, lightweight, and waterproof Dyneema® material. The black version uses an even more durable, but a few dozen grams heavier material – DCH150. Ultralight, durable, and versatile backpack for multi-day hikes and long-distance trails for true ultralight and thru-hiking enthusiasts. ## Versatile backpack for trekking The versatile Junction backpack with a volume of 55 liters **offers a wide range of options and uses**. Thanks to the roll-top closure and two compression straps on each side of the backpack, you can easily reduce or increase the volume as needed. When you don't need the extra volume, **you can roll the roll-top closure down** enough to make the volume resemble that of a smaller backpack [Junction 40](/p/hyperlite-mountain-gear-junction-40l). Junction is a versatile companion that **feels at home in practically any environment and conditions**. It performs excellently on narrow overgrown paths where you sometimes have to push through, on winter hikes, in rocky terrain, in humid conditions, and of course on classic mountain treks. It finds its use in more challenging weekend trips, multi-day mountain crossings, and long-distance trails. Backpacks from Hyperlite Mountain Gear are among **the most used on long-distance trails in the USA**, such as the Pacific Crest Trail and Continental Divide Trail, which, in our opinion, speaks for something. (This information is based on annual surveys on the [halfwayanywhere.com](https://www.halfwayanywhere.com/trails/continental-divide-trail/cdt-thru-hiker-survey-2020/#thru-hiking-gear) blog.) ## Specifications **External pockets**: The side pockets are made from a very durable strong material, Hardline with Dyneema®, which allows the backpack to withstand pushing through narrow overgrown trails. The large front pocket is made from sturdy mesh with an elastic rim, so you can easily dry wet gear in it and water simply drains away in the rain. **Hydration reservoir compatibility**: Inside the backpack, there is a mesh pocket measuring 20,3 x 35,6 cm for a hydration bladder and a loop for hanging it. On one side, there is an opening for the drinking tube covered with a flap and Velcro. **Hip belt and hip padding**: The hip belt is padded with a firm yet comfortable closed-cell foam and is equipped with a spacer mesh. **Loops**: Loops for attaching an ice axe and a central loop between the shoulder straps for lifting the backpack. **Top compression strap**: Y-shaped top compression strap – designed to secure or attach gear (jackets, tents, sleeping pads, etc.). **Chest strap**: Vertically adjustable and removable chest strap with self-tensioning elastic strap. **Backpack reinforcement**: Two removable aluminum stays are inserted in separate sleeves and secured with Velcro. **Reinforcement of stressed areas**: Reinforced bartack stitching. **Daisy Chains**: Daisy Chains on the shoulder straps allow for attaching pockets, for example, [Hyperlite Mountain Gear Shoulder Pocket](/p/hyperlite-mountain-gear-shoulder-pocket). **Zippered pockets**: Two spacious zippered pockets on the hip belt made of Hardline material with Dyneema® featuring waterproof #5 YKK zippers and an HMG pull tab. **Top closure**: Roll-top closure system with Velcro and straps with buckle for vertical compression. **Back panel**: The back of the backpack is padded with an integrated thin but stiff foam panel with a thickness of 0,63 cm. **Side straps**: There are 2 side compression straps on each side for securing gear and horizontal compression. **Shoulder straps**: Shoulder straps made of Hardline material with Dyneema® with padding made of comfortable closed-cell foam and spacer mesh. **Buckles**: Four external buckles on the back of the backpack for additional straps – [Gear Pack Accessory Straps](/p/hyperlite-mountain-gear-pack-accessory-straps) (not included in the package). **Seam sealing**: All side seams and seams behind the attached components of the backpack are sealed with waterproof tape. **Accessory options**: [Shoulder Pocket](/p/hyperlite-mountain-gear-shoulder-pocket), [Versa](/p/hyperlite-mountain-gear-versa), [Pods](/p/hyperlite-mountain-gear-pods). **Waterproof**: Yes. ## Technical parameters - **Inner** **volume**: 55 liters - **External** **volume**: 9,8 liters - **Weight**: 975 grams (size M) - **Load** **capacity**: up to 18,1 kg - **Width of the back panel**: 27,5 cm - **Upper circumference of the backpack**: 95,3 cm - **Bottom circumference of the backpack**: 85,1 cm - **Height of the fully unrolled backpack**: 74 cm The specified parameters are for size Medium. ## Materials Dyneema® fiber is a revolutionary material not only in the outdoor industry. With its remarkable strength-to-weight ratio, it is **the** **strongest fiber in the world**. Dyneema® fibers are 15x stronger than high-quality steel, lightweight, abrasion-resistant, waterproof, and resistant to UV radiation and chemicals. The **HMG Junction** backpack (available in both white and black) is constructed from hybrid composite Dyneema® fabrics—**DCH150** (170 g/m2), which is created by merging and laminating additional layers with Dyneema® fibers. This material excels in **high abrasion resistance, exceptional strength, excellent rip-stop properties, and impermeability to moisture**. Although the material itself is 100% waterproof, stitching creates tiny perforations. While most (more than 90%) seams in the backpack are taped, it cannot be considered completely waterproof. For full protection against water and moisture, we recommend using the backpack with [waterproof dry bags](/c/gear/drybags-and-organisers). ## How to choose the size? | Backpack size | Body length | | --- | --- | | Small | 38–43 cm | | Medium | 43–48 cm | | Large | 48–53 cm | | Tall | more than 53 cm | **If you are unsure about choosing the right size, you can contact us.
