Pros: fits the 80-size Spirit proton pack, if you get a mounting kit from eBay or Etsy.Cons: not very sturdy; smaller than official Alice frames; pricey for what you get.I wouldn't use this to carry anything super-heavy. It's great for cosplay though!

It's a bit weaker and thinner of a frame than I was expecting, but that keeps it mostly light. It's not exactly that comfortable but it's also not that uncomfortable. Main problem is the included straps were barely attached at all and were extremely cheap thin straps, fell off when I put it on, and luckily I ordered improved straps with much better padding and far better attachment clips when I ordered this so this could actually be considered usable.It feels like this was rushed to be put together, and I feel like this should've been half the price I paid for. However, for a back-mounted monitor project this was the only thing I could find anywhere under $100 that could work. Still feels like a bit of a ripoff given what you end up with.

2 runs, one at 56 pounds, other at 27, and the D ring broke, bad quality don't buyIve had only 2 frames and I had hundreds of rucks on the other one, this one is .
