SLEEVES

What arm sleeves are

Arm sleeves are removable knit tubes running from bicep to wrist — the most modular garment in the race kit. Marathoners start cool mornings in them and shed or roll them as the road warms; track athletes warm up in pairs and race in none, one, or two; and the single sleeve has become a sprint signature all of its own.

The jobs are plural: warmth without a jacket, sun protection in UPF-rated versions that block around 98% of UV, light compression, and — not to be underrated — identity. A sleeve is the cheapest way a kit says something personal inside a federation uniform.

How a piece of basketball medical kit ended up on Olympic sprint start lines is a genuine crossover story — charted above, told below.

The crossover story

The modern sleeve was born on 21 January 2001, when Allen Iverson took the court with a length of compression stockinette on his right arm — cut by 76ers trainer Lenny Currier for the bursitis in Iverson's shooting elbow — and scored 51 points. Under Armour later made him a nylon version, the league's stars copied it, and by 2008 sleeves were the NBA's most popular non-apparel item.

Running adopted the sleeve for its own reasons. Distance racing's version is thermal: at the 2018 Boston Marathon, run in near-freezing rain, the lead women's pack raced with arm coverage under their singlets — the sleeve doing a jacket's job at a fraction of the weight, ready to be discarded if the day warmed.

Sprinting stripped it down further, to one arm. Gabby Thomas, who races with a single sleeve, put the honest version on record: for many it is aesthetic, for her a cue — “a reminder out of the blocks to drive my arm up.” The compression science, for what it is worth, is modest: reviews find no clear performance effect and a positive trend in recovery, some of it possibly placebo. The sleeve's real cases are warmth, sun and self.

How a sleeve is built

Simple garment, deliberate details.

• The knitPolyester or nylon with elastane — a verified UPF model runs 67% recycled polyester, 25% polyester, 8% spandex.
• The gripperA silicone band inside the bicep cuff keeps the sleeve up through two hours of arm swing.
• The taperCut narrower toward the wrist so tension is even along the forearm — sized by bicep circumference, never by height.
• UPF versionsRated UPF 50, blocking about 98% of UVA and UVB — sun cover without sunscreen on ultra and trail days.
• Thermal logicWarm-up warmth that removes in seconds without touching shoes or bib — the whole reason marathon fields wear them at cool starts.

A pair weighs less than an energy gel, which is exactly why the cold-start calculus favours them.

How to choose yours

Choosing sleeves is a two-measurement decision.

• Measure the bicepSize by upper-arm circumference against the maker's chart; a compression sleeve fits slightly smaller than the arm, snug without pinching.
• Match the jobCool-start racing and warm-up: standard knit pairs. Sun: UPF-rated. Style or a technique cue: whatever colour tells your story — precedent says one arm is fine.
• Check the cuffThe silicone gripper should hold without leaving a ring; if it digs, go up a size.
• Pairs and singlesSleeves are sold as pairs; the single-sleeve look simply wears one and keeps a spare.
• Archive realityRace-issued sleeves are team accessories from a single cycle — small runs that match specific kits in the archive and do not restock.

However you wear them, they remain the only garment in this series you can put on, race in, and throw to the crowd — all in the same afternoon.
