Early Winters vintage bivy. Made in Seattle. Early Winters used an early Goretex fabric for the canopy that had a fussy interior laminate much like Bibler Todd Tex. I recently washed it, sealed the seams (Required 1&3/4 tubes of Seam Grip) and added Velcro to the hood. Blue panels are retro cosmetic and as designed. 1 lb 4 oz, size large. Good condition. Asking $95.00, shipped.  PPFF or please 3% for the fee's.

*Not certain but 'Early Winters may have been the first company to use Gore-Tex (brand name!) in outdoor products. ByroTex, Todd Tex, Integral Tex and Gore Tex are all the same material; expanded polytetrafluorethylene. Gore Tex no longer licenses its material for use in tents, thus the non proprietary versions in the various single wall tent manufacturers'.
