Two-inch polypropylene webbing. Stitched black leather ends. 41 to 72 inches. An extended end holding three picks. Picks not included. $13.99.

Seventy-two inches is why this strap is on the shelf. The other three straps here stop at 60, 60 and 56 inches, and that is enough for a guitar at chest height on a player of average build. It is not enough for a bass worn low — which is a playing position rather than a style, because it sets the angle of the right wrist — and it is not enough for a tall player, who reaches the last hole and finds the instrument still sitting too high. Six feet of strap solves both.

The other end of the range is worth saying too: it starts at 41 inches, where two straps on this shelf start at 35. This is not the strap for a child.

The stitched leather ends are the construction detail that matters. The two points where a strap fails are the ends, where the button goes through, and leather stitched to webbing lasts in a way molded plastic does not. It is also the part that keeps the instrument on the strap, which on this shelf is otherwise the job of the strap locks.

The pick holder takes three, on the lower front end. The shelf’s own reasoning is that a pick is lost every session and the only answer is having plenty — but plenty in a drawer in another room is no answer mid-song. Three on the strap is where a hand goes without looking.

What it does not include is the picks themselves. Stated twice in the listing: picks not included. One strap on this shelf arrives with six, and the strap locks here arrive with four. It is the holder, not the contents.

Two inches is standard width. The shelf’s reasoning says a wide strap spreads the weight and changes everything over a long session — two inches is where that starts, not where it goes. And no load rating is published, though it should be said plainly that no strap on this shelf publishes one.

The product record gives 91 g (3.2 oz).

The questions players ask

Why would anyone need 72 inches?

Two reasons, and they are both real. A bass worn low — which is a playing position, not a pose, because it changes the angle of the right wrist — can need a foot more strap than a guitar at chest height. And a tall player on a standard strap simply reaches the last hole and finds the instrument still too high. The straps on this shelf stop at 60, 60 and 56 inches; this one goes to 72. At the short end it starts at 41 inches, which is longer than the 35-inch minimum two other straps here offer, so it is the wrong strap for a child.

Does a pick holder on the strap actually help?

It gives the pick one known place to be, which is the whole problem. The shelf’s own reasoning is blunt: a pick gets lost every session, and the only practical answer is quantity — but quantity in a drawer in another room is not an answer mid-song. Three picks on the lower front of the strap is where a hand goes without looking. What this one does not do is supply them: picks are not included, stated twice, where one strap on this shelf arrives with six and a set of strap locks here arrives with four.
