The Original: D4 Full Size Portaledge
The D4 Full-Size Portaledge sets new standards in stormproof, compact, light, and easy-to-deploy
In 2017, John Middendorf produced the first expedition D4 portaledge for Marek Raganowicz, who then used it for an extreme expedition in Baffin Island where he lived in it for 30 nights on two new big wall routes. Since then, the D4 has gotten incredible acclaim, proven with over 1000 nights on the vertical, and widely acknowledged as one of the biggest innovations in big wall gear since the first A5 stormproof portaledge.
TO ORDER: The D4 full-size (82" x 47.5") portaledge is produced by Durango Sewing Solutions, in Durango Colorado. You can order the D4 full-size Portaledge here:
