Wildcat 8L Backpack

Wildcat 8L Backpack

Chest Rig add-on

The Wildcat Backpacks were designed to be ultra-comfortable and adaptable backpacks featuring 3 Liter / 100oz Hydrapak® water reservoirs with insulated hydration hoses. The Wildcat Tech adjustable shoulder straps with 5-position options fine-tune the fit for a custom-tailored feel for different-sized riders and gear.

Worn over a jersey, external armor, or a large ADV jacket, the ergonomics of the Wildcat Packs will evenly distribute the weight of the 3L reservoir, tools, and your essentials while avoiding pressure points and sore shoulders. The molded back panel and adjustable/removable sternum strap create maximum comfort and support for riding rough terrain in the backcountry.


Compared to the larger 12L Wildcat, this lighter-weight, smaller-volume 8L bag is stripped down to carry only the essentials. A more minimalist backpack for the necessities of fuel, water, and tools.Stash your goggles and spare lens in the fleece-lined pocket, throw your wrenches and pliers in the front tool organizer, and clip your InReach Mini to the shoulder strap for fast on-body access. 

The optional Wildcat Chest Rig pairs with the Wildcat 8L and 12L Backpacks. The Chest Rig is equipped with two front pockets, one designed to provide quick access and secure transportation for a satellite communicator, like the Garmin inReach and InReach Mini. Opening the main storage pocket, you’ll find a removable Velcro panel with elastic webbing to secure small items such as a pocket knife or charging cables, plus room to store your phone, wallet, snacks, or other quick-access items without having to take off your pack. The Chest Rig back panel is also equipped with MOLLE for attaching it to other Mosko bags/luggage with MOLLE panels.

Please note: the Chest Rig add-on is only available in Black. All three pack colors share the Black Chest Rig.

Wildcat 8L Backpack

The wildcat is well made, like all of the Mosko products. The shoulder straps are very comfortable and support the pack's weight well. I like the 3L water capacity and the expanding beaver tail. It’s big enough for an extra tube, tire irons, snacks, water, and a jacket under the beaver tail. I did an 80-mile loop and had everything I needed for the day. It is a small pack that will force you not to overload it with extra unnecessary items.

Dropped my Africa twin so many times on the ORBDR and has held up with no damage… well worth the cost of rugged luggage…

Wildcat 8L backpack

Great back pack, comfy, fairly light weight with good construction ☆☆☆☆☆. Needs to come with the rain cover as standard not a extra or make the whole backpack from Weather proof material.
