Every jacket comes with a SUPER FINE LINING. While in some jackets like PARKAS AND SNOW JACKETS, the lining is very heavy to produce a warm effect, in case of summer jackets, the inside lining is barely there because you will not be wearing them during low temperatures. So, when you buy, keep the purpose in mind and select a lining accordingly.http://www.kidswaterproofjackets.com/kids-jackets/
