Interesting; new to me too. Seems to be in the general weight range of a ULA pack (for example).

One way that they might be bringing the weight down, however, is to offer various add-on pockets and pouches separately (cost difference too of course), so one would want to think in terms of total cost and weight of the desired end product. The ULA that I use has built-in belt pouches and side & back mesh, none of which these KIFARU models include.

Still, a good sign to see more options, thanks for pointing this out.
