Sub Jacket Questions, Answered
What is a sub jacket?
A long, insulated coat worn by substitutes and squad members while they wait to come on. It goes over your kit to hold body heat in, so muscles stay warm rather than stiffening up in the cold.
Which size should I choose?
The size guide shows measurements of the jacket itself: chest, length and sleeve. Compare them with a coat that fits well. Kids sizes run from 4XS (Mini, about age 5 to 6) to XS (about age 11 to 12), and adult sizes from S to XXL.
Is it waterproof?
The outer shell is waterproof nylon, designed to keep rain out and deflect the wind while you're on the bench.
How does it fasten?
With hook-and-loop fastening instead of a zip, so it comes off in seconds when you're called on. Adjustable wrist straps help keep the warmth in.
Can I order for a team?
Yes. For larger orders use our bulk enquiry form, or call us on 01942 497707, and our team will send a quote.
How quickly will it arrive?
