Chafing

Chafing reference article on thruhikingwiki.com.

Overview

Chafing is skin irritation caused by repeated friction, often worsened by moisture, heat, and salt. It is common in long-distance hiking and can significantly affect comfort if not managed.

Key points

  • Chafing typically occurs where skin rubs against skin, fabric, or gear.
  • Moisture, sweat, and grit increase friction and irritation.
  • Common areas include inner thighs, underarms, waistbands, and pack strap contact zones.
  • Clothing choice, fit, and fabric type influence chafing risk.
  • Some hikers use lubricants, barrier products, or specific garments to manage chafing.
  • Persistent or severe chafing may require rest and targeted care.

Details

Chafing results from repetitive friction between skin surfaces or between skin and clothing or equipment. Over time, such friction can cause redness, tenderness, and in more extreme cases, broken skin. Long-distance hikers often encounter chafing in areas where movement is constant and moisture accumulates.

Factors contributing to chafing include sweat, rain, or humidity; salt from dried sweat; and small particles of dust or grit that become trapped in fabrics. Clothing that bunches, seams placed in high-friction zones, and ill-fitting waist or chest straps can all increase the likelihood of irritation.

Common strategies for managing chafing include selecting smooth, well-fitted garments, adjusting pack straps to reduce rubbing, and occasionally cleaning or airing out skin and clothing to remove salt and debris. Some hikers use lubricants or barrier creams in known trouble spots, while others rely on specialized undergarments or shorts designed to reduce friction.

If chafing becomes severe, it may limit comfortable movement and benefit from rest, gentle cleaning, and time out of aggravating conditions. In a long-distance context, learning early how personal clothing systems and routines affect chafing can help prevent repeated issues later in a hike.
