So I finally lit a fire under my own rear-end and got down to sewin'. This is what followed:

In hindsight, both packs are probably TOOOOO big, but no worries. It just means I have to make some more =D!
Pack 1:
No fancy name
Front/back/bottom: XPAC from rockywoods.com
Sides: 1.9 oz coated ripstop nylon
Size: 12"x6"x36"
Weight: 13.4 oz.
Nothing special– just a basic roll-top pack. The shoulder straps are rectangular, but sewn at an angle. The shoulder straps are sewn to the pack using a flat-felled seam and all other seams are finished with 7/8" grosgrain.



Pack 2:
Still no fancy name
Entire pack is rockywoods XPAC with heavy-duty mesh pocket against back for sit/structural pad.
Size: 10"x7"x22" with a 3" lift from front to back.
Weight: 11.4 oz.
This is my first panel-loader and I feel really good about how it turned out. The shoulder straps are just a layer of XPAC against one layer of 3D mesh form thru-hiker; they are finished with grosgrain, but I think in the future I will sew them inside-out, flip them and then put a line of stitching down each side. Again, they are just rectangles sewn at an angle.
