Shipping system for storing and/or transporting temperature-sensitive materials. In one embodiment, the system includes an outer box having four side walls, bottom closure flaps, and top closure flaps. A vacuum insulated panel (VIP) is detachably coupled to one of the top closure flaps and is removably covered by a cover. An insulation unit is removably positioned within the outer box, the insulation unit including a plurality of VIPs arranged to define a cavity bounded by a bottom wall and four side walls. A disposable liner is removably mounted on the insulation unit. The liner may be a thermoformed sheet and may cover the interior and top surfaces of the insulation unit. A plurality of temperature-control members and a product box may be removably positioned in the liner. Preferably, the liner is shaped so that the temperature-control members snugly fit around all sides of the product box.
