Welcome.
I would say first consider if you want that day pack to haul meat. If the answer is no, you can get away with a Lot less pack For a day pack.
short answer, if you are looking for a pack that will handle the tasks you described, a pintler or a sawtooth (or Terraframe 50) would be good options and a bit cheaper than some of the other brands. for a longer answer:
I have and have used a pop up for the last few seasons. The 38 is great for me for eastern deer hunting. It has enough room for cold layers and a night or two. However, it doesn’t replace a full size frame pack IMO so it is a bit of a niche play. I love that it is compact and can also haul fairly comfortably when needed. If I was looking for a do all pack, it would not be a pop up.
any of the full size frame packs mentioned above would fill the need. Keep in mind that you are hearing from a crowd that spends a lot of time in the field and a lot of $$ on gear. You don’t need to spend $700 on a pack to hit the woods for a couple days. The trying on packs thing is best and it is good advice, but it is impractical for most. you probably can’t go wrong with any of the brands mentioned here but some may fit you better than others. Unfortunately, you would need a few miles under those packs to know that for sure. If you have one, go over to your local REI and ask some poor clerk to help you with a pack fitting. That will help Give you some idea of proper fit.
for my part, I have too many packs. I use a pretty simple 22 L day pack for short trips and my pop up 38 for day trips with more gear or when I have to haul meat. I have an MR frame with a pintler and a Terraframe 80 bag (similar to the metcalf). Those cover me from light day trips to 5-10 days. I also have a seek pack I use for lightweight backpacking that weighs about half as much as my MR packs and frame. That is my “system” that I have evolved in 25 years of trial and error and is probably more than $2k of packs. Definitely not necessary but I share just to offer some perspective.
