An Ounce Of Prevention Is Worth At Least A Pound Of Cure

There's no way around it - getting caught out is not fun. Depending on the weather and terrain, it'll range from uncomfortable to dangerous. The O.N.S. system is designed to improve your chances so you can keep your wits, avoid the panic, and make good decisions. Astral developed the One Night Stand (O.N.S.) system so you'd have a backup plan in case of the unexpected. Pack it once and forget it. Until you need it.

The seatpost with O.N.S. is equipped with the O.N.S. emergency sleeve tucked carefully inside the post itself. It has you better prepared should things go sideways. Install it. Ride it. Forget about it. When you need it, it'll be there.

Seatpost:

  • 2014 T6
  • 10mm offset
  • Available in 27.2mm and 31.6mm
  • 350mm
  • The O.N.S. Includes:

  • Space blanket
  • Mini flashlight w/ AAA battery
  • Whistle
  • Waterproof Matches
  • Fire starter materials
  • Strike paper (for matches)
  • Water purification tablets for 3 quarts of water

  • *Note: It may be tempting to unpack the O.N.S. sleeve when you get it, but unless you are good at putting toothpaste back in the tube, we'd advise against it. The inside of a seatpost is tiny and the O.N.S. sleeve is tightly packed. It should be considered one-time-use.
