Personally, I’ve come along to settle where I thought I never would. If a packs not 2500-3000 cubic inches minimum, I’m not fooling with it anymore.
Day hunting in cold weather eats up pack space. In a hurry. I often walk in a single 250 merino or 200 weight polyester. Most times if it’s steep, I’m going to wear merino. I’m going to sweat on longer walks. So, I’ve got a lot of layers to carry.
I’ve settled on the woodman and DT3 for most everything. When I’m backpacking, I always carry the DT2. There is zero harm in cinching empty bigger bags down. But, it sucks to have to really get creative to get everything in a smaller bag.
I’ve never been a lid or Sherman kind of guy. And, as I’ve transitioned to better gear over the last decade, I’ve found I’d rather buy a bigger bag and only have to deal with those compression straps and zippers versus a smaller bag I have to supplement with pockets and pouches.
I used to wander why guts would buy a 4509-5000 ci pack as an all arounder versus a multiple bag approach. Using the 22 mag, hell bender, and solo with these accessories is a PITA. So, I now clearly see why guys do it. Now I wander why anyone would buy a day pack that requires all these add ons versus one bag that does all. YMMV.
