What a Gear Audit Actually Looks at Before a Backcountry Trip

The items that get flagged most often and why they matter

Most people who've done a few backcountry trips have a gear setup that works for the trips they've done before. The problem is that gear that's appropriate for a three-day summer trip in the Sierra is not necessarily appropriate for a seven-day autumn trip in the Wind Rivers. A gear audit is a review of your current kit against the specific demands of the trip you're planning, not against a generic standard.

Sleeping system: the most common gap

The sleeping bag or quilt is the item that gets flagged most often in gear audits. The issue is almost always the same: the bag is rated for a temperature that's warmer than the expected overnight low on the planned route. A bag rated to 30°F is not adequate for a route where overnight temperatures will drop to 15°F at elevation.

The fix is not always to buy a new bag. Sometimes a liner adds enough warmth. Sometimes the solution is to adjust the route to lower elevation campsites. The audit looks at the whole picture before recommending a purchase.

Water treatment: capacity and redundancy

A single squeeze filter is adequate for most summer trips. For a longer trip, or a trip in cold weather where the filter can freeze and crack, redundancy matters. A backup chemical treatment option, iodine tablets or Aquatabs, weighs almost nothing and covers the scenario where the primary filter fails.

The audit also looks at carry capacity. A 1-liter soft flask is fine when water sources are frequent. On a desert route where the gap between sources is eight miles, you need to carry three liters minimum, which means the carry system needs to support that.

Navigation: what happens when the phone dies

Most people navigate with a phone app, which is fine as a primary tool. The audit checks whether there's a backup. A dedicated GPS device or a paper map and compass is the standard recommendation for any route more than a day from the trailhead.

The audit also checks whether the digital maps are downloaded for offline use. Cell service in the backcountry is unreliable, and an app that requires a data connection is not a navigation tool in the field.

The gear audit is most useful when it's done four to six weeks before the trip, which leaves time to address the gaps without rushing a purchase decision.
