Got this in an email from MSR:
Thru-Hiking this Year? We Have Your Shelter Covered. Our new Thru-Hiker series of Mesh Houses and Wings were engineered for long-distance living. And we want to give you one to take into the wild. If you plan on completing a full thru-hike this summer, fill out our application to put one of these shelter systems #thruthepaces.
Please fill out our survey by March 17th. If selected, you'll hear from us by March 31st."
The link to the survey leads to: https://www.surveymonkey.com/r/NXB97QK
NOTE: I have no connection to MSR other than as an occasional customer; I also don't know any more about the offer than what I've posted here. If you don't want to click on the link, I am guessing that MSR has something on their website.
