I used to dismiss the idea of a tool belt .... until I had one.
They make a lot of sense for jobs around the garden - when you need multiple items to hand.
Load up with the tools you might need and save yourself the endless trips back and forth to the shed or greenhouse.
these are sized with the American workwear market in mind so;
S/M - from a 28" waist up to a 34/36"
L/XL - from 34" up to around a 44" waist
I'm around a 35" waist - sometimes I can wear 34" jeans, sometimes a 36". I wear a 36" in the Carhartt Bib Overalls. I can wear both sizes of the tool belt - the S/M at its maximum length and the L/XL at its smallest. I've chosen to go with the S/M as I personally prefer not to have the access strap on the L/XL
