If you want it for whitetail I think you’ll like the source. Get the ones they’re selling now in black and you’ll be using it a lot. The source is quiet for bow hunting and very packable. And then can be used later in the season as a midlayer under a windproof shell.
FL Source Vest is what I would use. The Sitka Ambient Vest would be another to look at. The Ambient is very light and packable but the wind will go through it. But as a layering piece under windproof garments I think it works great. The source vest is also very packable, quiet, and has more...
I would stick with something you know you can easily get off the shelf in a store if you don’t reload. Which what you’re using and just about everything mentioned here in the responses are.
+1 on Marisupal Gear. Just got the fully enclosed magnetic with the rangefinder pouches this year. I love it. I also have Rick Young Outdoors Basic Ultra Light Binocular Harness. I like this as a minimalist set up in a treestand.
