This Bowens Lumiair 60-80 Softbox (31.5 x 23.6 x 12.6") is a good choice for softening the output of your flash.
Precision tension ensures straight edges delivering clean cut-off of the light beam, while the optimum color calibration of the reflective interior surface together with shallow construction, offers a high degree of light efficiency.
Add to this two layers of diffusion and you have an even spread of light - no more than 1/2 stop from center to edge, without distracting hotspots. Each Lumiair softbox comes complete with a simple zip-up carry case to ensure safe and easy transportation to location shoots. Lumiair softboxes also include the main canopy, a rear cowl, front diffuser, internal diffuser and support rods.
Lumiair softboxes come with a 2-part speed ring - a basic ring accepts the rods and the included Bowens insert. There are also inserts available for most other flash head brands.
