I bought a Phase II Captain Rex helmet from a seller on Etsy for my son. The helmet looks very well made and is actually built around a heavy duty bicycle or motorcycle helmet. There's plenty of padding as well as lights (making this the only helmet I could find with lights). The only problem is that it uses the lens from the motorcycle helmet, which doesn't extend to the bottom of the "T. I found a replacement T-shaped clone-trooper lens on-line and I'm hoping it will fit, but I'm not sure how to adhere it to the interior of the helmet. It has padding all around. Foam-board friendly construction adhesive? Here are some photos of the helmet. The new lens should be here in a day or two, and I'm bucking the Christmas deadline so I need to get it right the first time. Any help would be greatly appreciated.
