A tent (10) with extendable windows (14) having a main structure (12) including a plurality of walls (16, 18, 20) which are oriented at a first angle (60) with respect to a vertical reference. The tent (10) also includes at least one window (14) which is extendable to a second angle (62) with respect to a vertical reference, where the second angle (62) is more negative angle than the first angle (60) thus producing windows (14) which are horizontally extendable further than the tent walls (16, 18, 20).
