Arc'teryx jackets have a cult following for their technical performance and in the world of outdoor gear, they're widely considered the gold standard. But there's one thing even I'll admit to its that the naming system can be somewhat confusing.

If you've ever stood in a store looking at an Alpha SV GORE-TEX PRO and wondered what those letters actually mean, you're not alone. Arc'teryx product codes aren't just marketing fluff. They're a clear way to understand how the jacket is built and where it's meant to perform.

Why Arc'teryx Stands Out: Born in British Columbia's Coast Mountains - a region where conditions can swing from sun to snow to sideways rain in the space of an afternoon. Sound familiar? For Kiwis, that's basically a stock standard day.

Gore-Tex Technologies: Your First Decision

At the core of most Arc'teryx shells is Gore-Tex but not all Gore-Tex is the same. Here's the breakdown:

GORE-TEX ePE

Best For: Everyday rainwear, hiking, mixed-use
Pros: Waterproof, breathable, eco-friendlier
Cons: Not as rugged as PRO

GORE-TEX PRO

Best For: Alpine, mountaineering, severe weather
Pros: Maximum durability & breathability, stormproof
Cons: Heavier, higher price

GORE-TEX PRO + Hadron®

Best For: High-output alpine, climbing
Pros: Light but tough, excellent abrasion resistance
Cons: Limited to premium alpine models

Think of it this way: ePE is your go-to for everyday wet missions, PRO is for those "this might get ugly" days in the hills, and PRO + Hadron gives you alpine-grade armour without the bulk.

SV, AR & FL: What the Letters Mean (Plus a Note on LT & Other Codes)

Arc'teryx's abbreviations are a quick guide to what a jacket is for, how tough it is, and the conditions it's built to handle.

SV – Severe Weather

Use: The roughest conditions, days of heavy rain, strong winds, or alpine snow.

Build: Tough fabrics (up to 100d), reinforced in high-wear areas, helmet-friendly hood, storm flaps, full GORE-TEX PRO.

In NZ: Fiordland's endless rain, winter climbs on Aoraki, or guiding in storm-prone areas.

Example: Alpha SV – $1,450, 100d GORE-TEX PRO shell built for extreme conditions.

AR – All Round

Use: Year-round versatility, handles rain, wind, and snow without being too heavy for fair days.

Build: Balanced durability, weight, and breathability. Uses GORE-TEX PRO with lighter panels for comfort.

In NZ: Routeburn Track in spring, ski touring in the Craigieburns, or commuting in windy Wellington.

Example: Beta AR – $1,000, mix of 80d and 40d GORE-TEX PRO, DropHood™ fits over helmets or hats.

FL – Fast & Light

Use: When speed and low weight matter, running, fastpacking, or quick alpine trips.

Build: Minimal features, lighter fabrics, packs down small. Best for short, high-output missions.

In NZ: The Old Ghost Ultra, bikepacking Alps 2 Ocean, or a quick summit on Taranaki Maunga.

Example: Norvan SL – ultralight shell that still keeps you dry when the weather turns.

What about LT?

Older Arc'teryx models sometimes used LT (Lightweight) for pared-down designs. It's been phased out, but the idea lives on in the current Beta, which keeps that lighter, streamlined feel.

Other Codes You Might See

SL – Super Light: Even more minimalist than FL, built for shaving grams.
IS – Insulated: Adds synthetic or down fill for cold conditions.
MX – Mixed Weather: Hybrid fabrics for durability and breathability in varied climates.

We don't currently stock these models, but they follow the same logic as SV, AR, and FL, helping you choose the right jacket for your needs.

Quick Comparison Table

Model	Best For	Gore-Tex	Weight	Price (NZD)
Beta	Hiking, everyday rain protection	ePE	375g	$650
Beta SL	Multi-day hikes, packability focus	ePE	340g	$820
Beta AR	Harsh weather, versatile alpine	PRO	461g	$1,000
Alpha	Technical alpine routes, climbing	PRO / Hadron®	370g	$1,150
Alpha SV	Severe alpine storms, mountaineering	PRO	485g	$1,450

Choosing the Right Jacket for NZ Conditions

New Zealand's weather is famously unpredictable, so think about your worst-case scenario, not just your best.

Fiordland & West Coast

Multi-day storms, extreme conditions

→ Alpha SV

South Island Alpine

Tramping, winter trips, versatile use

→ Beta AR

North Island Tramping

General wet-weather, everyday use

→ Beta

Pro Tip

If you'll only own one jacket, lean toward AR models - they strike the best middle ground between weather protection and everyday wearability.

Perfect for New Zealand's unpredictable conditions where you might face sun, rain, and wind all in one day.

Layering for Performance

Arc'teryx shells work within a layering system. The shell itself is for weather protection; it won't keep you warm without help underneath.

Base Layer

Merino or synthetic to wick sweat (Icebreaker, Arc'teryx Rho)

Mid Layer

Fleece or synthetic insulation like Arc'teryx Atom LT

Shell

Your chosen waterproof Arc'teryx jacket

NZ Pro Tip: Always carry a mid-layer, even in summer. Weather can change in 10 minutes!

Care Tips for Longevity

Arc'teryx jackets are an investment, treat them like one.

1. Wash Often

Dirt and oils clog the membrane. Use tech wash like Nikwax.

2. Reproof Regularly

When water stops beading, reapply DWR treatment.

3. Tumble Dry Low

Helps reactivate DWR without damaging fabric.

4. Store Properly

Never pack away wet - mildew and odor will set in.

Final Thoughts: Buy Once, Buy Right

Arc'teryx doesn't make fashion jackets, they make survival tools. By matching the right Gore-Tex membrane and model to your activity, you're investing in gear that will perform when you need it most.

Whether you're battling Fiordland storms, summiting Mt. Taranaki, or just want a rain shell that won't quit after a season, understanding these tech codes means you'll buy smarter and stay safer.
