I'm with SB. I have always used a small blind bag. They fit under the backrest of a layout blind easy without your weight on them and in a regular blind or boat blind take up alot less space. If organized well you'd be amazed how much you can fit in one. I am still using the avery bag I bought well over a decade ago. Mine is no bigger than the smaller one you listed and I carry up to four boxes of ammo if needed, usually just two though, a set of needle nose pliers, a folding knife, a multi-tool, can of rem oil, cleaning rag, bore snake, licenses, regulations pamphlet, chokes, choke wrench, calls, camera, spare layout blind seat clips and pins, headlamp, face mask, 2 sets of gloves, a toque, a couple # 4 buckshot loads in case a yote stalks the decoys(had it happen a few times), a few loose upland loads in case I encounter huns or ruffies and a bird lanyard and spare hat clipped to the clips on the bag ends and I usually throw my wallet in the waterproof license pouch inside.
