Reposhing this item I purchased from @willscoolcloset. I have used woolino sleep sacks for several years and love them but my daughter quickly outgrew this. Used a handful of times. VGUC. Woolino is awesome bc you never worry if they’re too hot or cold (a constant worry for me). Because of the Marino wool, it regulates their body temperature all the way from low 60s to mid 70s. When looking at used Woolino listings, make sure they show you the interior. The interior is the Marino wool, and it can tear if not taken care of. This one is in very good condition on the inside and outside and has never been put in the dryer and the delicate cycle and detergent has been used. No known imperfections. Feel free to ask any questions! From a smoke-free, dog friendly home.
