I'm in a similar situation, except the exact opposite. My recommendation is to have someone with experience and knows what they're doing to handle that. I'm pretty sure I exclaimed "I need an adult" when I realized I shouldn't be handling a thread and needleThanks guys! Now I gotta get my padding put in the helmet and locate the neck seal.
Vest fits good but gonna have to add a slit down the back and get it hemmed up so I don't "hulk" out in this thing. I know jack squat about doing that or if it'll even work. Open to suggestions on that one.
