Some follow-on comments after a mid-fall 5-day trip.
  • Camped at a ginger ale-colored meadow lake that noticeably slowed flow, and a clear-water backflush sped it up nicely. The best indication it's slowing is difficulty clearing air from the lines and filter.
  • Good for MSR using clear silicone tubing. It doesn't kink, doesn't flavor the water, doesn't stiffen when cold, and doesn't hide air bubbles.
  • The 10-liter bag opens up dry camp options. Lug 20+ pounds of water in from the nearest source and you'll be good until the next day.
  • Don't forget to bring the filter cartridge into the tent on sub-freezing nights. Pop it into a ziplock bag to keep things dry.
