NABS spent considerable time choosing the cap we'd wear. We spend considerable time hiking, sweating and working and we didn't want a cap that would cause more sweating. We wanted a cap to keep sun off our head and allow for cool ventilation, I know we found the right one. This is our second purchase of this cap and the first with our new NADS logo. We have had MANY requests for a hat so we have listened and we have listed it. It is tan in color with navy blue trim, has a velcro attachment at the rear and one size fits all.
