Klein Tools 60011 Standard Hard Cap, Blue

One standard size covers head sizes 6 through 8, adjusted with a full 6-point ratcheting suspension. The ratchet lets a worker dial the fit one-handed without pulling the cap off, which is why a single size works across a crew.

Yes, there are accessory slots at both sides for the Klein 60060 face shield and other protective gear, but the slots need the Klein 61970 universal slot adaptor to accept them. Order the adaptor along with the shield or the shield will not mount.

Headband clips on the 60011 are made to hold Klein 60040 goggles either over the eyes or parked on the front of the cap. That keeps the goggles with the hat between tasks instead of in a pocket.

The 60011 is a cap style, meaning a front brim only rather than a brim all the way around. Cap style is what most electricians and interior trades wear because the short back clears a raised head in tight or overhead work; a full brim is the pick when the job is outdoors all day and sun or rain off the neck and ears matters more. The 60011 does include a rain trough to shed water off the back of the neck.

It weighs 13.6 oz (386 g). Comfort features include a porous brow pad for ventilation and a nape strap that holds the cap firmly so it does not shift when a worker looks up or bends over.

The straps and bands are washable and are shrink- and stretch-proof, so they can be cleaned and put back in service rather than swapped out. That matters for MRO and facility stock where hats get reassigned between workers.

Blue shell. Overall dimensions are listed as 10 in (25.4 cm) height, 9 in (22.9 cm) length and 7 in (17.8 cm) width, which is what to work from when sizing gang boxes or shelf space for a set of caps.
