I've used the Stearns 1K-116 for a couple of years and have had them
abused by rocks in class 1 & 2 rapids without any damage. They bundle
up into a suitcase sized bag and weigh about 38#. Also, their
customer support is excellent - I damaged a seam in the outer cover
through my own neglect and they replaced it without question within
the warranty period. Don't leave a fully inflated boat on deck and in
the Florida sun all day!
