The tents of the Classic + series, like all Mammoth series, have a high light reflectance, are airtight and light-tight. The Classic + series is the golden mean between LITE + and PRO. They differ in the quality of the inner reflective material (Mylar 600D) and also in the overall sophistication of the tent. Compared to the PRO version, the Classic + version has a less solid construction, fewer holes, the material is less reflective and is also part of less interior equipment.
