Black and pink cap from Wild Roses, a famous mountaineering brand that has now withdrawn from Japan, with an adjustable back strap. - Color: Black/Pink - Design: Sporty design - Back strap: Adjustable back strap I bought this because I like Wild Roses (mountaineering brand), but although it's a free size, it's about an S size and was a little too small for me, so I haven't used it much.
