Fitly - Sub180 - Adventure Running Pack - Edgy Black

The Fitly Sub180 Adventure Running Pack is designed for those who need more carrying capacity without sacrificing running comfort. This pack is built to hold all your running adventure accessories. It is constructed from resistant rip-stop fabric and offers significantly more storage compared to previous Fitly packs. The Sub180 can also function as a super light day pack, trail running pack, or for fast-hikes.

The design of the pack is based on three core principles:

• Balance: This pack features a 5L volume of storage compartments in the back, complemented by four front pockets. These front pockets are ideal for spot hydration, nutrition, a phone, and other accessories. Wide shoulder straps connect these sections, enhancing comfort and distributing weight evenly. Two heat vents are strategically placed at the apex to increase cooling in areas where heat typically accumulates.
• Triangulation: The upper side webbing attaches to the back of the pack, naturally pulling the load closer to the runner's back. This design significantly reduces left-right swayings, which are common with many loaded running vests made from stretchy fabric. While stretchy fabrics can be comfortable, they are often inadequate for countering load swaying with every step.
• Expandability: The side panels of the main compartment are made from stretch material. This allows the pack to remain flat when empty and become more voluminous when filled. The stretch fabric also applies pressure to the load, preventing items from rattling while you run. This same expandability feature is incorporated into all four front pockets.

Hydration is a key focus of the Sub180, and it includes:

• Bladder1100: A 1.10 L (37 oz) low-profile soft bladder. Unlike traditional bladders, the Sub180's custom bladder is super thin and malleable, designed to conform to your body's contours. It shrinks as you drink, minimizing sloshing and making it barely noticeable.
• Flask250: A 250 ml (8.5 oz) soft flask for the front pocket. The Flask250 is a popular small flask.

A notable innovation in the Sub180 is the bladder pocket, which is made with Tyvek. This technical fabric is very light yet super strong, and it reflects heat and cold. This feature keeps your liquid cooler (or warmer) 30% longer without the need for thick and heavy insulation.

Additional features of the Sub180 include:

• One size fits all, accommodating sizes from XS to XL (24 to 48 inches).
• Side attachment points for running poles.
• A clever bilateral integrated tube attachment mechanism.
• A water resistant back pocket.
• Soft flask elastic retainers on each upper front pocket.
• S.Café eco-friendly, moisture-wicking, and odor-resistant fabric.
• Lightweight, durable, and extremely tear and abrasion-resistant fabric.
• Completely silent zipper tabs.
• Adjustable sternum straps.
• A smooth fabric glass pocket and an internal zip pocket for valuables.
• Front and back safety reflective bands, plus a security whistle.
