Fixing HH impertech that doesn't keep you dry.
HH impertech guide jacket+ rain and heavy winds= being miserable, cold and wet.
Go over every seam with seam sealer (that little tube of seamgrip). Take your time and don't miss a single seam, keep it clean, the stuff is messy.
Spray the inside material with Kiwi Silicone Camp spray so that the inside won't get soggy. Keep it turned inside out to let it dry so the stench goes away. Do a second coat.
No more wet shoulders and neck, and wet waist area where the inner fabric wicked water and soaked you.
Cheap rain gear made better.
