Down is sold by a number 🔢 and judged by a measurement, and the two rarely agree. This is the bench where you settle it. Lay a duvet, a top quilt, a sleeping bag, a jacket, a vest, booties or a pillow out chamber by chamber, give it a construction 🏗️, a shell and a fill grade, and the arithmetic returns the grams each chamber needs to stand at the loft you asked for, the loft the finished piece will carry, and the temperature that loft holds. Then it reads the design back and names the cold spots before you cut anything: the sewn-through seam carrying too much loft, the chamber left short that will shift, the one overstuffed into dead loft, the bag with no differential cut that will squeeze its own inner shell. When the piece is finished, photograph it lofted on its side beside a card of known height, set the three guide lines on the frame, and it converts pixels to millimetres and gives you the loft you actually got, and from that the fill power you actually got, printed against the figure on the label. Everything is computed on your device 📱 from your own numbers, offline 📴, with the formula shown beside the result.
**Joker Glitz** lets you build 🔨 a piece chamber by chamber and watch 👀 every gram change as you work, read 12 fill grades from Hungarian goose down to short-staple synthetic, compare ⚖️ 8 baffle constructions drawn as live cross-sections, diagnose 9 cold-spot faults, follow a 6-stage washing and storage regimen, measure 📐 real loft from a photograph, and keep every piece and every reading on a bench that charts measured against designed loft over time.
With **Joker Glitz**, every calculation stays on your device 📱, giving you a clear way to compare your design, construction and measured results. Use **Joker Glitz** to understand exactly how your insulation performs from the first calculation to the finished piece.
