Glossary

The vocabulary that shows up on Free Drop product pages, on the labels themselves, and in the corners of the internet where this gear gets traded. Fabric technology first, then brand marks, then how to read a label, then the trade terms.

Fabric & technology

Dri-FIT

Nike's moisture-management platform, trademarked in the mid-1990s and sitting inside the broader NikeFIT apparel system that began in 1991. Nike describes it as a high-performance microfiber construction that pulls sweat off the skin and spreads it across the fabric surface so it evaporates faster. Worth knowing: there is no single Dri-FIT fabric. It is an umbrella applied across many recipes, which is why a 2001 polo and a 2008 polo can both be truthfully labelled Dri-FIT and feel nothing alike.

Dri-FIT UV

Dri-FIT behaviour combined with a minimum UPF 30 rating. Nike's own golf material named it as a distinct sub-system.

Dri-FIT Body Mapping

Ventilation zones placed inside Dri-FIT fabric at the points that actually get hot, rather than symmetrically. Visible as denser fabric at the chest and shoulders with lighter mesh under the arms and down the back.

Therma-FIT

Nike's warmth family, trademarked alongside Dri-FIT. The cold-weather counterpart — fleeces, linings, and layering pieces.

Storm-FIT

Nike's weather-protection family. Names the intent, not the construction: Storm-FIT tells you a piece is meant to handle weather, but the seam package is what tells you whether it is genuinely a shell.

Clima-FIT

Nike's wind-resistant, breathable tier, sitting between Dri-FIT and Storm-FIT in the same naming system.

NikeFIT

The umbrella, dating to 1991, that groups all of the above into dry, warm and weather categories. Reading a Nike garment as part of a system rather than a standalone product is usually the fastest way to understand it.

ClimaLite / Climacool

Adidas's two adjacent platforms, and a clean illustration of different engineering priorities under similar names. ClimaLite is moisture transport, closest in logic to Dri-FIT. Climacool adds ventilation and mesh at sweat zones on top of that — it started in tennis polos, launched in running shoes in 2002, and spread through apparel in the mid-2000s.

Hydrolix

Oakley's moisture-management label. Product-facing, with less disclosed technical detail behind it than Nike's FIT names.

DryScience / Breath Thermo

Mizuno's paired climate system — DryScience moves sweat out, Breath Thermo turns absorbed moisture into warmth. Same underlying physics as its competitors, organised as a system rather than a single feature.

Microfiber

Polyester spun to a very fine filament. More filaments means more surface area and more capillary pathways, which is why microfiber genuinely wicks better rather than just feeling softer. The phrase on old Dri-FIT copy is doing real technical work.

Denier

A measure of yarn thickness. Denier-differential fabrics use different weights on the inside and outside face to move moisture in one direction — Nike's later patents describe exactly this mechanism.

UPF

A fabric's ultraviolet protection rating, not a sunscreen rating. UPF 30–49 is very good, 50+ is excellent. It depends on fibre, colour, knit density, stretch and wetness, so a stretched or damp garment protects less than the label implies.

DWR

Durable water repellent — the finish that makes water bead on a shell. It wears off with use and washing, and its absence is a condition note rather than a defect.

Delamination

When a laminated or coated inner layer separates from the face fabric with age. Reads as bubbling, flaking or a sticky inner surface. Always disclosed.

Brand marks & sub-brands

Software

Oakley's outerwear line — vented pullovers, ski shells and technical jackets carrying Software labelling. The most collectible Oakley apparel designation, and a +5 bonus in Free Drop's scoring rubric.

Thermonuclear Protection

Oakley's own name for its moto-derived archive language: bold colour, reflective detail, high-tech fabrics, aggressive silhouettes. Oakley still frames the archive this way, which makes it a useful term rather than a nickname.

Eyeshade / Eye Jacket / X-Metal / Juliet

The Oakley eyewear canon — the mid-1980s shield, the 1991 Eye Jacket, and the 1997 arrival of investment-cast metal frames. Apparel from the same years reads as the same engineering argument in fabric.

Yin Yang

The symbol carried by the first Tiger Woods and Nike co-branded line in 1998. Its presence dates a piece precisely, and it predates the TW mark.

TW logo

The familiar Tiger Woods monogram, dating from 2000. Yin Yang first, TW second — that sequence is one of the most reliable dating tools inside Free Drop's era.

Nike Golf Shield

Nike's golf-division badge, introduced in 1998 when Nike split golf into its own business and used through roughly 2007 before being phased out in a brand reset. It ran alongside the swoosh, not instead of it — a golf-specific mark layered onto product that still carried the swoosh everywhere else. Nike brought the shield back in 2026, so a shield on its own now means 1998–2007 or 2026 and later. Corroborate it against the tag, the fabric and the cut. More on Dating Nike Golf.

Trefoil / Equipment / Badge of Sport

Adidas's three logo eras, and an unusually workable dating tool. Trefoil signals heritage and Originals, the three-bar Equipment mark belongs to 1990s performance from 1991, and the Badge of Sport arrives in 1996 and carries performance product from there.

Golfman

Ashworth's mark, sketched on a napkin in 1987. Ashworth is the brand that made relaxed all-cotton golfwear viable against a polyester-era default, and was the number one golf apparel brand by 1997.

RLX

Ralph Lauren's technical golf line, launched around 1998–99, as distinct from Polo Golf's resort and lifestyle positioning from roughly 1989–90.

Reading a label

Tag era

The period a garment's neck and care labels belong to, inferred from their format. Collector guides map Nike across pinwheel, blue-label, grey-label and later production-tag formats. These guides are community-built rather than official brand documentation, so they are strong supporting evidence and weak standalone proof.

Wash tag

Usually the most honest surviving document on a garment. US law requires fibre content, country of origin and the responsible company, plus separate care instructions — so the inside label is generally more reliable than the logo on the chest. Verify the wash tag first, then the technology story, then the graphics.

Care symbols

The standardised symbol language introduced in 1963, indicating the maximum severity of treatment a garment tolerates. Text-heavy labels, mixed text-and-symbol labels and symbol-only labels can each hint at a different production period or export market.

Country of origin

An era signal rather than a value in itself. For Nike Golf in this window, Mexico, Thailand, Malaysia, Indonesia and Hong Kong are all period-correct — Nike was producing across 35 to 38 countries. "Made in USA" and "Made in Japan" carry a collector premium in vintage sportswear because they correlate with pre-outsourcing production, but origin alone does not make a piece valuable.

Style code

The internal product number on the inner tag. On some brands it encodes season and year — Patagonia has coded items since 1988 and added colour codes from 1995. On Nike Golf of this era there is no single universal format, which is why dating leans on several signals at once.

Trade terms

Deadstock

Never worn, never sold. Original tags where they survive. Used literally here, and rarely.

One-of-one

A single garment, not a size run. Everything on this site is one-of-one, which is why sold pieces stay listed rather than disappearing.

P2P

Pit to pit. The chest measurement taken flat from underarm seam to underarm seam. The most useful number on any vintage listing.

HPS

High point of shoulder. The reference point for a length measurement — where the collar seam meets the shoulder, straight down to the hem.

Fits like

Free Drop's call on what modern size a garment actually fits, independent of its tag. Explained in full on Sizing.

Drop

A dated release of pieces around a theme. Free Drop's drops keep their page permanently — when the next one launches, the last becomes part of the archive rather than being taken down.
