The PackTowl UltraLite can absorb 400mL or 13.5 fluid ounces of water, whereas the Matador NanoDry absorbs less than half that amount, about 150mL or 5.1 fluid ounces of water. The PackTowl UltraLite is almost the same size as a regular shower towel, whereas the Matador NanoDry is slightly smaller. The UltraLite is also thicker, softer and less sticky. However, because the PackTowl UltraLite is thicker, it dries slightly slower. It dries 82% faster than a cotton towel, whereas the Matador NanoDry dries 100% faster than a cotton towel. The PackTowl UltraLite also weighs more, coming in at 90 grams or 3.2 ounces, whereas the Matador weighs just 68 grams or 2.4 ounces. Another advantage that the Matador NanoDry has is that it has an antimicrobial coating, whereas the PackTowl UltraLite does not.
