The Airlite Towel Small is the smallest regular size in Sea To Summit's ultralight microfibre line, measuring 80 × 40 cm and weighing just 30 g — 50% lighter than the older Pocket Towel, per the manufacturer. The 85% polyester / 15% polyamide blend gives the same high absorbency as the larger sizes in the range: over three times its own weight in water, with the same sub-30-minute drying time.
After use it packs down to 4.5 × 4.5 × 4 cm, smaller than a matchbox, making it a solid pick for ultralight kit lists where every gram counts. A sewn-in loop lets you clip it to a pack to finish drying while walking.
Given its smaller area, it suits drying your face and hands or backing up a bigger towel rather than serving as an all-purpose shower towel — a good option for hikers trimming the weight of their wash kit.
