45L Ultralight Pack Liner – Recycled PE Sold in packs of 10 Ultralight pack liner bags made from exceptionally tough polyethylene with 50% recycled content. Designed for backpacks of 30 - 45 litres, these 3D gusseted liners expand naturally to conform to the shape of modern packs while reducing wasted space compared to traditional flat pack liners. The gusseted construction helps the liner sit neatly inside the pack with less bunching and improved volume efficiency, especially in narrower ultralight backpacks. Despite their low 32g weight, the material is highly durable and tear resistant, making them ideal for long-distance hiking, backpacking and everyday trail use. I carry an extra one as my trash bag.
