I love the FJN in Cordura, it is beautiful!
However, I always feel less nervous taking Dyneema accessories and bags under "field conditions" which could be snowy, muddy, wet, sandy...
I admit, many times "the field" is only the local shops, there Cordura is great!
On my way in, I am really careful to protected my Cordura Cafe Bag from precipitations. I have no such consideration for the Packing Cube
Backpack that has been part of all of my outings since last summer.
In truth, I want the Synapse in Ultraviolet and would be thrilled with a matching FJN to coordinate with everything else in Ultraviolet.
Purple being my favorite color
