Description

The Cobalt™ Skull Cap, or "Skully," is the first hard shell skull cap made exclusively for umpires, designed in collaboration with MLB and MiLB. Featuring a new, smooth matte finish that delivers a sleek, professional look and reduced glare, the Cobalt™ offers both style and performance behind the plate.

Engineered to defend against bat backswings and add an extra layer of force reduction, it’s built like a coach’s helmet but enhanced with specialized padding, refined contours, and umpire-specific design features for baseball and softball.

The shortened bill mimics an umpire plate/combo (4-stitch) cap and fits comfortably under any brand or style of mask, not just All-Star models.

FEATURES

Smooth matte surface
Shortened bill fits with plenty of space in any umpire mask
Tough and durable polycarbonate shell
Augmented padding in key zones along sides, rear, and top for added protection against bats
Removable padding system is machine washable
Fitted S to XL sizes to fit most head sizes. All-Star took head measurements of 50 MLB umpires to get the sizing right.
Bill length is 1 1/2"
Weight: 13 ounces

Care

Interior: Remove the 3 pad which are Velcro'd in roof and headband of cap. Wash pads with warm water and mild soap. Rinse well and let hang dry in a well ventilated space
Replacement pads available directly from All-Star
Clean the interior of the cap with a water/soap solution applied to a towel or use a disenfectant wipe
Exterior: Apply a damp cloth to buff scratches smooth

Official Review: All-Star Cobalt Umpire Skull Cap - Regular Matte

The All-Star Cobalt Skull Cap is the first hard-shell skull cap designed specifically for baseball umpires—developed in collaboration with Major and Minor League Baseball. This updated model features a smooth matte finish, replacing the previous sand-matte texture, for a sleeker, more professional look that pairs seamlessly with today’s umpire masks and harness systems.

Works and fits well. Provides improved protection over wearing a hat below the mask.

Excellent product, the day after I received the Cobalt helmet, I was hit in the head with the full force of a bat in the head. Had it not been for the new helmet, I would have been in the hospital! All my fellow umpires viewed the incident from the camera video feed at the Ripken Experience in Aberdeen.

I don’t know why I didn’t order this helmet earlier than I did. It fits well, is comfortable and has great air flow through it. It gives me the confidence of further protection that I need, since the topic of head/ brain injuries are so prevalent in sports today and raise a concern for all involved.

Q:	I wear a 7 1/8 hat; what size cap do I need? – Howard Graham
A:	The Medium size (7 - 7 1/8) is the recommended cap for you. – Brandon Lawson Support Specialist, Pro Umpire School Graduate and Umpire, Football Official & Basketball Referee

Q:	Can you get it in Navy Blue? If not is navy blue gonna be out in the future? – Michael Almony
A:	Currently, we only offer this skull cap in matte black. – Sherie Sandifer Office/Service Manager

Q:	Where can I get replacement pads? I love my helmet but I lost one of the pads. – Jody Jackson
A:	Replacement padding for this skull cap can be found directly from All-Star. – Sherie Sandifer Office/Service Manager

Q:	How well does this work for a 7 3/4? My experience has been that these are just too snug. – Peter Sheward
A:	A 7 3/4 cap size falls within the range of the X-Large. With Free Returns, there is no risk in trying it on for fit. – Cortney Anderson Customer Service Specialist

Q:	Will the umpire helmet fit a Force3 umpire mask? – Joseph Morton
A:	Yes, this skull cap pairs well with a Force3 Defender umpire mask. – Ben Kirk Brand Manager

Q:	My biggest concern about this is the size. I usually get a 7 1/8 and stretch it (I actually have a hat stretcher). A 7 1/4 is too big and tends to come off when I remove my mask. A stretched 7 1/8 works perfectly. So it looks like the 7 - 7 1/8 will be too tight as it’s unstretchable and the 7 1/4 will be too loose? – Mike Melkonian
A:	It appears you fall somewhere between the L and the M size. With Free Returns, it's advantageous to order both sizes, use the Free Shipping* offer, and return the size that doesn't fit quite right. – Hunter Fry Supplier Relationship Manager, Customer Service Specialist, Former Basketball Referee

Q:	My hat size is a L/XL. Will a L/XL size skull cap work for me? – Luke Arakawa
A:	This skull cap comes in individual sizes—S, M, L, XL. The L is recommended for cap sizes 7 1/4 - 7 3/8 while the XL is 7 1/2 - 7 5/8. Please determine your cap size using our Fitting Room. – Brandon Lawson Support Specialist, Pro Umpire School Graduate and Umpire, Football Official & Basketball Referee

Q:	I wear a 7 3/8 hat. Will the LARGE be too small/tight if it's for 7 1/4 - 7 3/8? – Bob Levine
A:	This is the best recommended fit for a size 7 3/8. The Medium size will most definitely be too small and the Xtra-Large much too big. – Ty Unthank Marketing Specialist, HS & College Umpire

Q:	Does this perform differently than the sand finish one? Do mask harnesses "stick" better, or is it mostly/completely an aesthetic issue between the matter and sand finishes? – Mike Wolff
A:	Both are equally protective but this matte surface does not scratch as easily as the sand matte does. Mask harnesses made with a tackified surface like the All-Star Delta Flex Umpire Mask Replacement Harness are becoming more common so the grip aspect of the cap surface is no longer the greater priority. – Ty Unthank Marketing Specialist, HS & College Umpire
