I recently led a hike in the Bear Mt. area with two of my teenage nephews. We field tested a small Lightload towel against as MSR pack towel of the same size. Both towels absorb the same as we found while drying off tent flies after a rainy night. But a distinct advantage of the Lightload is that you can ring much more water out of the fabric than the MSR, therefore making it more absorbant after the initial use, which allowed it to dry much faster than the MSR.
The Lightload was used, dryed by hanging on pack, and then re-used 4 times, while at days end, and after only 1 use, the MSR was still damp and heavy. The Lightload also, obviously packs smaller. Time and again, when we needed to dry something, such as ourselves after cooling off in a stream, we reached for the Lightload. Also, the LL is a fraction of the price of the MSR. The only catagory where the MSR may be superior is durability, but we can continue extended field tests to determine the durability of the Lightload.
