Fly Your Tent Down the Freeway

The original Mountain Safety Research Newsletter (1969-1982), written by MSR Founder Larry Penberthy, is always a fascinating read. The newsletters are filled with extensive and technical product testing and mountain safety information. However, Larry and his team were also known to have some fun.

One of our favorite features in this vast newsletter archive is the makeshift “wind tunnel” testing report in Issue 7 (April 1973) for the new MSR Mountain Tent. Important performance features of the tent are profiled under the headings “More Room,” “Condensation,” “Doors,” “Ease of Erection,” “Wind Stability,” “Cookholes,” “Materials,” and “Weight.”

Within the “Wind Stability” description, the reader is given this glimpse into MSR’s rigorous and fun DIY testing methods. It’s true that Larry was never satisfied until he personally put gear through the ultimate paces.

Tent Testing April 1973

The original color photos from this wind tunnel testing have lived in the MSR archives for the past 41 years, and have been blown up and hung on the wall in the upstairs lobby of one of our Seattle manufacturing buildings.

The 1973 newsletter also features a testimonial from “Antarctica and expedition veteran” Bill Lokey, who rode in the tent “at 50mph and said it is the quietest tent he has ever been in at a similar air speed. Tested endways, sideways and 45°, all OK. We know wind can get stronger, but this test is fairly severe.”

And there you have the roots of the MSR tent design, research and testing program.
