A bump cap helps you avoid unpleasant encounters of the painful kind. These are not approved for use where "hard hats" are required but are ideal when working in attics, crawl spaces or other places where hard objects might unexpectedly appear in your path. They are much lighter in weight than an approved hard hat so they`re significantly more comfortable. Caps are vented allowing the scalp to breath and providing comfort on hot work days. The bump caps are made of durable, impact-resistant, high density polyethylene and have a four-point adjustable suspension with a sweatband. Fits sizes 6-1/2 to 8 and available in Blue, Yellow or White. Made in Mexico.
