Innegra is an olefin fiber. Olefin is a synthetic fiber made from a polyolefin such as polyethylene or polypropylene.
Many paddlers will surely have an orgasmic interest in knowing that this is an olefin:
Olefins are used in many fabrics and materials for clothing, home furnishings and automobiles. Some trademarked olefin materials we non-orgasmic canoeists may be familiar with are: CoolMax, Hollofil, Thermoloft, Tyvek, Polar Guard, Trevira, Thinsulate.
"Innegra S" is just the olefin fiber. That's not what's in canoes. "Innegra H" is used in canoes. It's a composite material where Innegra S is interwoven with either fiberglass, carbon or basalt to make a "H"ybrid. The interweaving is done at the filament level.

I'd be interested in seeing impact, compression, bending and weight tests for Innegra H versus some other hybrid composites already used in canoes -- such as Wenonah's "Tuf Weave", which is a bi-weave of fiberglass and polyester, and Nova Craft's "Blue Steel", which, according to the NC website, is an "advanced Aramid Carbon material combined with Spectra". Is that Greek or cake?
Me . . . I know what cedar and ash are. Although I'm not sure what aluminum actually "is", I can recognize it.
