Weather is an important factor in your packing . If it is cold , you could wear a jacket , a sweater , a regular shirt , and a tee shirt . Layering up will keep you warm , and it will leave more room in your bag .

a regular shirt 指的按正常体型和服装标准缝制的衣服,也就是市场上出售的衣服.与特体服装相对.Layering up 同时穿几件衣服.本文指"多穿几件衣服既保暖,又可在包里腾了更多的空间."
