D4 Big Wall Gear Update

…winding down Australian production…

It has been a great process these past four years designing new portaledges and creating small production batches to continuously improve and innovate the portable ledges (portaledges) used for climbing and other purposes. However, it has gotten too complex to expand production, as designing and producing high tech outdoor goods, where the materials need to be imported, and the product mostly exported, is challenging.

The good news is that everything learned here, along with expert feedback from climbers all over the world, is available online at bigwalls.net, and as things progress I plan to create a more clear manual on how to design and produce high quality portaledges.

So it’s very unlikely I will have more D4 Delta2p’s for sale from Australia, as I am working on a final production batch, and most of these have already been spoken for. I can and will continue to make custom portaledges upon request for expeditions that really need an advanced tool, and currently have two Delta3p’s available, and am planning to supply these to cutting-edge expeditions that need the most robust and functional three-person single point hanging tent system possible. If interested, please email deuce4@bigwalls.net

I plan to work on my writing again, and hope to first revise a long article I originally wrote for Ascent, 1999. I have shared this mail list with my Substack blog, here is the link: https://bigwalls.substack.com/p/coming-soon?r=bftho&utm_campaign=post&utm_medium=email&utm_source=copy

Thank you again for your interest in my design work, it has been a pleasure.

Kind Regards, John Middendorf
