It's a reddish, bright red color. I purchased a red and white hat (size M) made of heat-shielding material for sports day practice, but it seems a bit too small because I wear my ponytail high. I will buy a larger size. Used for only about an hour during physical education class, and already washed. The neckband is well-designed, so it should last a long time. The back stretches with elastic. Shipping via Yu-packet Post Mini or Nekopos. Please check your head size before considering. This red hat has UPF50+ to block heat and keeps the internal temperature at -2.6℃. - Color: Red - Size: M, L, LL - UPF: UPF50+ - Temperature effect: -2.6℃ Thank you for looking.
