Almost forgot that thread... I took the pics of the ILBE packs family.
The whole ILBE pack family comparison with a (repro) TAD FAST-PC v2
Main pack (front) with Source WXP hydration pack attached to the front
Main pack (back). Gen2 but with Gen1 straps and Gen1 lid retrofitted with Gen2 buckles.
Assault pack (back)
Main pack with assault pack attached (front).
Main pack with assault pack attached (side).
Overall: I love it.
