"Montbell UL Thermawrap Jacket Exceloft (1.8 oz/yd2) Ballistic Airtight Nylon 8.0 (360)"
8.0 ounces is about 224 grams using two significant digits for the conversion; not 360. Using an extra excel column to do this conversion instead of typing in in manually will reduce the chance of further human error.
Great comparison article, thanks!
