✷ The RSD Cargo Base Layer
Ditch The Pack.
Ride Free.
Three rear stash pockets carry your phone, multi-tool, snacks and a 350ml soft flask flat against your back. Nothing bounces on the descents. Nothing digs into your shoulders on the climbs. Nothing to unclip when you want a drink.

✷ Step 1
Pick Your Fit
Same three-pocket cargo system, cut two ways. Both are compression fit and true to size. Between sizes? Always size up.
Not sure on size? Compression fit, true to size, and if you are between sizes we say size up. Still stuck, email us and we will pick it for you.
The 3-Pocket Cargo System
✷ How It Works
Your Pack, Rebuilt
Into The Base Layer
A backpack puts 2kg on your shoulders and a wet patch down your spine. A hip pack swings on the rough stuff and has to be unclipped to reach. We moved the storage into the one thing you were already wearing.
- 1
Left Pocket · Tools
Multi-tool, tube, levers. Held flat and silent so nothing rattles down a rock garden.
- 2
Centre Pocket · Phone And Fuel
Phone, keys, gels, snacks. Secure against your body over technical terrain, not swinging off your hips.
- 3
Right Pocket · Hydration
A 350ml soft flask rides in the outer pocket, off to the side. Reach it and drink without stopping or unclipping a thing.
✷ Why Riders Switch
Four Things You Feel
On The First Ride
This is not a jersey with a pocket sewn on. It is a compression base layer engineered to carry load without moving.
Carry More
Three rear pockets for phone, gels, tools and a soft flask. Ditch the pack.
Stay Dry
Moisture-wicking fabric pulls sweat off your skin on the long climbs.
Ride Longer
Flatlock seams sit flat against the skin. No bunching, no chafe, hour four included.
Ride Lighter
85% recycled polyester with 15% elastane. Trail ready, planet conscious.
✷ Straight Comparison
Cargo Base Layer
vs Everything Else
Four ways to carry your kit on a trail ride. Here is how they actually stack up once you are moving.
| RSD Cargo Base Layer | Backpack | Hip Pack | Plain Base Layer | |
|---|---|---|---|---|
| Carries phone, tools, snacks and a flask | Yes, three rear pockets | Yes | Some of it | Nothing. You still need a pack |
| Weight on your shoulders | None, load sits on your back | Straps loaded all ride | None | Nothing to carry |
| Sweat down your back | Wicking fabric, nothing trapping heat | Guaranteed wet patch | Mostly clear | Clear, until you add the pack |
| Bounce on rough descents | Compression fit holds gear still | Shifts and sways | Swings on the hips | Nothing to bounce |
| Reach your kit without stopping | Yes, rear pockets | Stop, unshoulder, unzip | Rotate and unclip | Nothing to reach |
| Wearable under a jersey | Yes, pockets still reachable | Over the top only | Yes | Yes |
| Crash cover | 40% off a replacement, no time limit | None | None | None |
| Extra kit to buy, pack and clean | None, it is your base layer | A whole separate item | A whole separate item | A pack, on top of this |

✷ Before You Buy
Every Question We Get About This Base Layer
Answered straight. If yours is not here, email us at contact@rubbersidedown.com.au and a human replies.
Will the pockets bounce when they are loaded?
No. This is a compression fit, so the fabric holds whatever you load against your body rather than letting it swing. That is the whole reason it beats a hip pack on technical terrain. Riders have run phone, tools and a full 350ml flask through rock gardens with it.
Is this just a jersey with pockets?
No. A jersey hangs off you. This is a compression base layer, so it sits against the skin, wicks sweat and keeps the load still. You can wear it on its own in summer or under your jersey when it cools down, and the rear pockets stay reachable either way.
How should it fit?
Compression fit, true to size. The fabric stretches to mould against your skin without restricting movement. If you are between sizes, always size up. Men's runs S to 3XL, women's runs XS to 2XL.
Should I tuck it in?
No. The Cargo Base Layer is designed to be worn untucked so the three rear pockets stay accessible while you ride. Tucking it in defeats the point.
Will it be too hot in summer?
It is a moisture-wicking fabric built to move sweat off your skin and dry fast, which is exactly what you want on a hot climb. It is also the layer that replaces a backpack, and a pack is the single hottest thing you can put on your back.
Will it pill or fade?
The fabric is built to last. Our team has worn the same base layers for over a year of regular riding with no stretching, pilling or fading. Wash cold and air dry to keep it that way.
How do I wash it?
Cold machine wash, air dry. Skip the dryer and the fabric softener. Both shorten the life of compression fabrics.
What is the Crash Commitment?
If you crash and damage your gear on the trail, we give you 40% off a replacement. Just send us a photo. The Cargo Base Layer is covered, with no time limit. See how it works.
How fast does it ship?
Australia wide: $10 standard (4 to 7 business days) or $15 express (2 to 3 business days), and standard is free on orders over $90. New Zealand from $12 and United States express $17 USD. All orders ship from Australia.
What if it is not right for me?
You have 30 days from delivery to request a return or an exchange. Item needs to be unworn with tags in its original packaging, and return postage is on you. Email contact@rubbersidedown.com.au and we will walk you through it.
