D4 Trapeziums production ledges shipping

D4 Trapezium Update

The Trapezium is a new concept in portable ledges.
Prior to 2017, we had:

  • 0.5 ledges (i.e. Metolius Gizmo)

  • 1 person ledges (Metolius, BD, Fish)

  • 2 person ledges (A5 Alpine Double, Runout UL Ledge, Metolius)

  • Full size and 2+ person ledges (A5 Diamond Ledge, Cliff Cabana).

The Trapezium is a first in a new category, the "1.5 ledge". Big enough for one person as a personal bivy, and roomy for two people sitting up to stay out of a storm. Packs to 24" tall--daypack size. Lots of other new innovations in portaledge technology for fast deploy in bad conditions. 

"Make portaledges portable again!"
--John Middendorf

D4 Trapeziums have made it to the production phase (John Middendorf is hand making these in Tasmania), and shipping has begun.  Users consistently reporting positive feedback for a number of different endeavours using this new light and compact revolutionary shelter.

Our next batch will likely be a larger batch for the September big wall season.  We expect to be shipping early August for this batch.  If you have signed up on the mailing list at http://www.bigwallgear.com/d4-trapezium.html then there is nothing more you need to do, though if you have a specific project you need it for this year, be sure to email me and let me know specifics and timeframes, as I am always interested in cool adventures and how the ledges are getting used.  We really appreciate your support!

All the best on the big stones and the trees, 
John Middendorf
