I picked up a nice Nomad LT recently but the webbing was trimmed for an "average" size person. I'm not average. 6'4" 350 with a long torso and a thick frame. I can let out the straps and the shoulder straps will fit fine but I need a lot more to get the waist strap and crotch strap to close. Any ideas on how to lengthen the straps? I was thinking I could use some tri glides to "weave" in an extension.
