Helpful Positive Review
by Uncle Eddie, from AR, United States Updated on December 22, 2023
I only have a few miles on this pack but I can tell that it can handle it all. I loaded it heavy for a two night camp with my grandson and it was very comfortable. We didn’t go very far but I felt that I could have gone all day! I liked that I could expand it and then clench the load up tight.
Pros:
  • None
Cons:
  • None

Pros:
  • None
Cons:
  • simple
  • no front mesh pocket, side pocket is not very easy to access to water bottles.

If you are looking for a lightweight heavy backpack, Flex Capacitor is very worth considering. The comfortable load can be up to 15kg, there is no bragging at all, the waist bags on both sides are very practical, if you remove the built-in water bag, you can reduce it 100g, highly recommend this product
