★ New, Unused, with Tags Montbell Ear Warmer #1 [Unisex] This warm ear warmer uses a wool blend yarn with excellent heat retention on the outside. I am selling it as I have no opportunity to use it. [Material] Outer Ear: 85% Acrylic + 15% Wool Inner Ear: Chamois™ [Polyester] [Color] Navy (NV) [Size] Free Size [Folded Size] Φ12.5 x 7.5cm ◇ Excellent heat retention despite being thin This material is made by densely knitting extremely fine microfibers, which are one-tenth the thickness of human hair. Despite being thin and lightweight, it can store a lot of air between the fibers, providing high heat retention. ◇ Quickly releases stuffiness It has a good balance of heat retention and breathability, effectively releasing stuffiness even in situations with high activity levels. ◇ Provides stretchability It has excellent stretchability and is comfortable even in situations with high activity levels. Thank you. Ear warmer, ear muffs, montbell, ear muff ear warmer earwarmer ear warmer
