The new 12 liter hollow core Rob Allen float has a great new design. The new profile packs up in your Sportube much better than the older models. We took this float out and gave it a good run in the clearest water we've seen all year. We really liked the way it sat in the water, highly visible to boat traffic and really tough. I ran this float together with a Floatline Bungee Combo and had a great wahoo setup. The Polyethylene shell is the same material that kayaks are made out of. They can take an absolute beating and still perform.
