The patented HUG CLOSURE system provides benefits that traditional blankets cannot. Horse owners may adjust the neck opening size. The HUG unique chest flap design eliminates shoulder rubs. Nothing fits like a HUG!. The wrap-around front panels on HUG Closure Blankets are attached by custom-adjusted elastic straps to fit any horse. The panels act like a wrap-around shirt...there is nothing to bind or inhibit the extension of the horse"s shoulder or restrict movement. In addition, the elastic neck straps allow the horse to expand the neckline when he gets up or down or while grazing. The Abrazo Hug Sheet is Waterproof Breathable, Features 600 Denier outer, Nylon lining, no fill, a Tail Flap, Bias Surcingles, and Removable Elastic leg straps (for easier blanket washing). It comes in 2 traditional colors (Navy/Grey and Hunter/Purple) and 1 fun color (Teal/Orange)! Friesian A: Has the same back length (53" withers to tail)as a size 80" horse blanket. The only difference is the neck; the neck size is equivalent to a size 84" or 86" blanket. If you measure completely around the base of the horse"s neck, following the slope of the shoulder, it would fit a horse measuring 58-64".
