What waist sizes does it fit?

25 to 47 inches; SPIbelt sells a separate Slim model for smaller waists.

In Austin, Texas, according to SPIbelt.

Is a running belt better than an armband?

A belt keeps the weight at the waist instead of on one arm, and its pocket also holds keys and cards; an armband usually holds only the phone.

What can the SPIbelt Original hold?

A large smartphone, keys, cards or gels in its single expandable pocket.

Can you wear the SPIbelt under a shirt?

It is a slim belt with a low-profile pocket, so it can sit at the waistband or under a loose shirt.

Why this gift works

The SPIbelt Original is a slim elastic running belt with a single expandable zip pocket, 8 by 4 by 2 inches, that SPIbelt says holds larger smartphones - including the iPhone 13 Pro Max and Samsung Galaxy S20+ - along with keys, cards or a gel. It adjusts to fit waists from 25 to 47 inches, weighs 82 grams and is made in Austin, Texas. This listing is black with a red zipper.

It solves the most common running annoyance: where to put the phone and keys. It sits at the waistband instead of weighing down one arm, so it suits road runners who want their phone for maps, safety or a ride home without wearing a vest. It is a low-risk gift - one size fits most, and it is useful from the first run.

Who is this gift for?

Great for

A road runner who carries their phone in one hand
A first half-marathon
Walkers who want their hands free

Think twice if

They need to carry water
Their phone is unusually large

The catch

It has one pocket and no bottle holsters, so it carries small things only, and the maker's phone list stops at iPhone 13 Pro Max and Galaxy S20+ sizes - check the fit for a newer oversized phone in a bulky case.

Skip if they run long trail routes and need to carry water - a hydration vest or a belt with bottle holsters suits them better.
