GoBlow Stacks Explained — Single, Double, Triple and When to Use Each

May 9, 2026 · Shopify API

Most carry systems try to do everything at once. One bag, one pouch, one compartment that's supposed to handle every situation. The result is always the same: too much in one place, nothing organised, everything mixing with everything else.

Built for this? See Stacks deep-dive.

Stacks are the opposite. Three separate configurations — Single, Double, Triple — each designed around one specific carry problem. They thread together, they come apart, they live in your pocket without announcing themselves.

What Stacks actually are

Cylindrical machined stainless steel vaults. Threaded ends. Each unit is a self-contained sealed chamber, and the units thread together so you can carry one, two, or three chambers in a single stacked piece.

machined stainless steel marine-grade stainless — same alloy as the pendant range
Machined threads on a male and female end so units interlock cleanly
Independent caps — each chamber opens on its own, without disturbing the others
Cylindrical profile — sits flat in a pocket, doesn't print through fabric

They're small. Most people see them online and assume they're scaled up. They're not. Deliberately sized to disappear into a pocket, not to announce themselves.

The Single — 19×63mm

One chamber. 19mm in diameter, 63mm tall — slightly shorter than a stack of three coins, slightly thicker than a marker pen.

Who it's for: the minimalist who wants one sealed compartment and nothing else. The first-time Stacks buyer who wants to understand the system before scaling up. The everyday carry user who pairs it with a pendant and considers the carry complete.

The answer to "I want one piece, I want it sealed, I want it to disappear in my pocket."

The Double — 21×65mm base

Two chambers. 21mm in diameter, 65mm tall when stacked. The key thing: it's not just "more space than the Single." It's two completely separate compartments. Each chamber opens independently. What's in one never touches what's in the other.

Who it's for: people who want to keep two loads completely separate. Couples or pairs splitting one carry. The traveller who wants different contents available at different points of a trip.

If the Single is the minimalist's answer, the Double is the organiser's. Don't mix your loads.

The Triple — 18×80mm base

Three chambers. 18mm in diameter, 80mm tall when fully assembled. Designed to be the longest piece in the range without becoming awkward.

Who it's for: festival weekenders — three days, three chambers, one per day. Multi-day events where you need to carry enough to get through the entire weekend without going back to a bag. The Triple is the answer to "how do I do a three-day festival without a bumbag."

How threading works

Each chamber has a male thread on one end and a female thread on the other. They screw together in sequence. The system is genuinely modular — not just "three things that come in the same box."

You can run a Double as a Single by removing one chamber
You can run a Triple as a Double or Single by removing chambers
Each unit's cap is independent — opening one doesn't affect the others
The threads are machined tight enough that nothing rattles or works open in a pocket

Festival use

Three days, no bag, no bumbag, no constantly going back to the tent. The Triple is the answer.

Day one in chamber one. Day two in chamber two. Day three in chamber three.
Sealed against rain, dust, dropped drinks, and crowd compression
Reads on a security pat-down as a piece of metal carry, not a problem
Stays in your pocket from the gate to the headliner

Nightlife use

The Double is the cleaner nightlife carry. One chamber for the start of the night, one for later. Or one for you, one for your partner. It's slimmer than the Triple, longer than the Single, and the two-compartment logic maps perfectly onto how a real night actually unfolds.

The full carry system

Pendant on the chain. Stack in the pocket. That's the entire system.

Pendant on the body — always with you, scales from the gym to the rooftop dinner
Stack in the pocket — Single for the day, Double for the night out, Triple for the festival

Where to start

Most people start with the Single — cheapest entry point, covers everyday use, teaches you how the system works. Most people upgrade to the Double after the first festival. The reasoning is always the same: "I should have brought two of these." A small number start with the Triple, usually because they're already festival regulars and they know exactly what they want.

The right Stack is the smallest one that solves your specific carry problem. Start small. Add chambers when the use case demands it.
