I’m rocking a RX3 backpack since November 2024 and I still like it! It’s big but not ordered unless you’ll use these packing cubes.
On the website they say:
1 x 10L packing cube with breathable mesh
1x 5L shoe packing cube
1x 15L drawstring bag
The 5L shoe packing cube is to small for someone with avarage size shoed. It's a bit unclearly named on the website because in the photo you can see that Reyllen sees the drawstring bag as a shoe bag.
Though, these small bags looks en feels off high quality. Two of them came with loops so you can hook it on the hooks inside your RX3/Venture backpack. Unfortunately the drawstring bag doesn’t have any loops.
