Hey, fellow satchel convert! I snagged my Hiker a couple weeks ago after seeing it on a thru-hiker vid, and it’s already my new trail BFF for keeping gels and bars handy without digging into my pack. On your anti-sway question, I clipped mine to my Osprey pack’s sternum strap using two short Voile Nano straps (about 12″ each) looped through the satchel’s side loops-zero sewing, super secure, and it pops off in seconds for town mode. No pendulum chaos on descents now, and it stays put at chest level.
For bottle hacks, vertical works best for a 1L Nalgene in the main pocket (it fits snug without printing much), but I added a DIY elastic loop from some ¼″ shock cord sewn into the side for horizontal access-keeps it off my ribs and lets my phone ride separately without getting wet from condensation. Super cheap mod, adds like 10g.
Counterbalance-wise, with my 12kg pack on a 20km alpine day, it did ease shoulder pressure noticeably after hour 4-no placebo, my traps thanked me. Haven’t tried cold-weather yet, but layering under the puffy seems key to avoid sweat soak.
Loving the multi-use ideas-I’m rigging mine as a filter holder next trip. Pics of my clip setup if I can figure out the upload! What’s your pack setup?
