It’s also an estimate as when you order, you’ll let them know the exact main/reserve you’ll be using and they will size according to their experience with those canopies.

riggerrob 558 #3 August 7, 2023 Yes, the Javelin sizing chart lists canopy square footage/area. However, canopy pack volume can vary widely depending upon the materials. Dacron suspension lines pack bulkier than Spectra and Spectra is bulkier than the latest HMA/Vectran, etc. Also different canopy fabrics have different pack volumes. For example, a speed-wing/pond-swooping canopy made of heavily-coated sail-cloth will pack much bigger than a similar canopy made of ZPX (low pack volume) 1.1 once fabric. The extra ribs in cross-braced canopies also increase pack volume. The good news is that the Javelin sizing manual tries to accommodate all those variables by being biased towards the most popular canopies in are square foot range. For example, since the most popular 47 square foot canopies have extra ribs, sail cloth and skinny suspension lines, all those factors were considered before they were listed on the Javelin canopy compatibility chart. Oh! And if the chart says that a particular combination will be "stupid tight", be nice to your packer and buy the next larger size container. Quote Share this post Link to post Share on other sites
