Dream sheet / liner

Dream sheet / liner reference article on thruhikingwiki.com.

Overview

A dream sheet or liner is a lightweight fabric insert used inside a sleeping bag or quilt. It can add a small amount of warmth and help keep the primary insulation cleaner.

Key points

  • Made from materials such as silk, synthetic blends, or lightweight cotton.
  • Provides a washable layer between the sleeper and the main bag.
  • May offer a modest increase in warmth depending on fabric type.
  • Can be used alone in warm conditions as a minimal sleep cover.
  • Adds some weight and bulk, which hikers weigh against benefits.

Details

Dream sheets or liners are used by some long-distance hikers to maintain cleanliness and extend the effective life of sleeping bags or quilts. Instead of washing the primary insulation frequently, which can be time-consuming and may reduce loft over many cycles, hikers can wash liners more often with less impact on performance.

Liners come in different materials, each with trade-offs. Silk is lightweight and compact, synthetic fabrics may dry quickly and be more durable, and certain cotton or blended options, while familiar, can retain more moisture. The degree of added warmth varies and is typically modest compared with the core bag or quilt.

In warm climates or low-elevation sections, some hikers sleep in a liner alone, using the main bag only when temperatures drop. Others bring liners primarily for cleanliness and comfort, accepting the small increase in pack weight.

The choice to carry a liner depends on personal preferences around sleep comfort, hygiene, and gear maintenance. For some, the benefits are significant; for others, a liner feels unnecessary.
