Gossamer Gear G4-20 V2 Ultralight 42L backpack

Gossamer Gear G4-20 Ultralight 42L backpack

The backpacks capacity consists of the main compartment of 30L and the remaining 12 liters in the external pockets. The pockets on the hip belt are not included in the capacity of the backpack, only the outer pockets on the sides and the large mesh pocket.

G4-20 is made of 70D Robic Ripstop Nylon with reinforcements in 100D Robic Ripstop Nylon.

As with all frameless backpacks, it is important that you pack smartly so that the bag will rest comfortably against your back. In this model there is an updated type of seat pad (Molded G Sit Pad) that ensures that the backpack stays reasonably stable and extra comfortable.

G4-20 is available in three lengths and two colors. “Electric Blue” is available in small, medium and large. "Titanium Gray" on the other hand is only manufactured in medium and large.

Recycled Robic Nylon

As part of Gossamer Gear's commitment to reducing our environmental impact, we are transitioning to PFAS-free recycled fabrics across all of our packs.

Refined Hardware

Each buckle, zipper, and cord has been scrutinized for lightweight function. Get ready to meet a simple, cost-effective pack designed to lighten your load.

 

New Colorways

Our fan favorite Tropical Mist colorway is now available for the G4-20! We're stoked to bring you more vibrant option for showing your style on trail.
