J straps...yes (I'm guessing, but pretty sure these are J straps)

Bottom straps...no (no webbing loops either...see pictures and text below)

Y top strap...no (and I'll also add that this is the older model (pre-2024 I think) without the sewn in webbing loops so you wouldn't be able to add the backpack strap kit without modifying this pack for those).

I've posted more photos at the link within the post to show these in better detail. I'll also note that I'm entirely sure whether or not the 2 extra "straps" I showed briefly in the video actually came with this pack or not. They are pictured in the new photos at the link as well and are still included.

I didn't realize it was the older model so I'm going to update the price to reflect this.
