How to Use This Calculator

Enter group size, trip duration (days), remoteness (frontcountry, backcountry, or wilderness), and activity risk level (low, moderate, or high).
Remoteness and risk level determine which extras are added, such as elastic wraps, emergency blankets, and SAM splints.
Read recommended kit quantities: adhesive bandages, gauze pads, moleskin pieces, and pain medication doses.
Check total kit weight in pounds and ounces, along with the risk multiplier and items-per-person-day figures.
Ensure at least one group member has Wilderness First Aid (WFA) or WFR certification before heading into remote terrain.
