What is the difference between the Roo Single and Roo Single UL?

The biggest difference between the Roo Single and Roo Single Ultralight is the weight and suspension of each hammock. The Roo Single weighs 10 oz and has a 400 lb capacity, while the Roo Single UL weighs 5.6 oz and features a 300 lb capacity. The Roo Single UL also utilizes an ultralight toggle suspension system to cut weight, instead of carabiners.
