The T-Rex and Pterodactyl Jumper is made for little ones who love to dream of prehistoric adventures. Set against a classic base, it features a 'friendly' T-Rex and his Pterodactyl pal, giving a playful touch to their everyday wardrobe. Trotters have used a premium blend of merino wool and cashmere to ensure it feels lovely and soft against delicate skin while helping to keep the chill away on autumn walks.
