Our extra soft, double-brushed cotton flannel sheet set, exclusively woven for us in Portugal from the purest cotton - organically sourced and 100% certified. The plush fabric also resists shrinkage and is specially dyed so colors stay bright. Crafted from 100% certified organic cotton flannel. Brushed on both sides for an extra-soft hand that gets even softer with every wash. Some lint buildup in the dryer screen is a natural result of brushed flannel construction and should decrease with each washing. 5 oz. midweight is comfortable year-round. This product is tested for harmful substances. Extra standard pillowcases (set of two), sold separately. Set includes one fitted sheet, one flat sheet and two cases; twin set has one case. Certified by Control Union CU 812190, GOTS certified. Made in Portugal. Organic Flannel Sheet Collection Sea Salt Twin L.L.Bean
