Canvass and Nylon Tents
Innovation in tent designs has continued since. Nylon, which was lighter weight and not prone to mildew and rot, gradually replaced canvas in the late 60's. Eureka! introduced the first double-wall tent construction (a tent and fly), the Mt. Katahdin, which significantly reduced condensation problems.
Then in 1973, the company marketed the first self-supporting lightweight backpacking tent, the Timberline, which has become a staple for the Boy Scouts, and has sold more than two million to date.

In recent years, camping equipment has again been evolving, becoming more compact, lighter weight, quicker to assemble, take down, heat up and light up - all to accommodate the rapidly growing outdoor recreation market.
