Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Consumer Contract Regulations (CCR)

What are the Consumer Contract Regulations?

Under the "Consumer Contract Regulations, you have the right to cancel an order for goods made at a distance. These rights start from the moment you place your order and ends 14 days from the day you receive your goods.

Your right to cancel

Your right to cancel an order for goods starts the moment you place your order and ends 14 days from the day you receive your goods.

This 14 day period is the time you have to decide whether to cancel, you then have a further 14 days to actually send the goods back.

Your Right to a Refund under CCR

You may get a refund within 14 days of either, the trader getting the goods back, or you providing evidence of having returned the goods (for example, a proof of postage receipt from the post office), whichever is the sooner.

A deduction can be made if the value of the goods has been reduced as a result of you handling the goods more than was necessary. The extent to which you can handle the goods is the same as it would be if you were assessing them in a shop.

Refunding the cost of delivery

The trader has to refund the basic delivery cost of getting the goods to you in the first place, so if you opted for enhanced service e.g. guaranteed next day, it only has to refund the basic cost.

Exemptions

There are some circumstances where the Consumer Contracts Regulations does not give you a right to cancel. These include CDs, DVDs or software if you've broken the seal on the wrapping, perishable items and tailor-made or personalised items. They also include goods with a seal for health protection and hygiene reasons that have been broken or tampered with, e.g. Climbing Equipment and PPE.

My goods are broken

If you feel that your item is defective/broken/faulty and it is still under warranty, please contact our Customer Support team([email protected])with as much information as possible with regards to the fault, including photos if applicable.

We want to reduce our impact on the environment as much as possible, the first step for this is reducing our waste. Therefore, please note that we will always offer a professional repair in the first instance; if the product can be repaired.

This may involve your product being sent back to our suppliers or to a professional repair company. Please note that due tovaried procedures, warranty claims and repairs can take between 2 and 4 weeks to be concluded

Osprey Ozone Hardside Four-Wheel Carry-On Expandable 34 Plus10L Black

Season:AW26

Brand:Osprey

Code:3655-550

Osprey Ozone Hardside Expandable 4-Wheel Carry-On 34+10 Overview

The Ozone Hardside Expandable 34+10 builds on Osprey's premium lightweight luggage platform, offering the same durable protection and effortless mobility as the standard model — with added flexibility when you need more space.

Designed for professionals, frequent flyers and adaptable travellers, this carry-on expands by 5cm, adding up to 10 litres of extra capacity. It maximises overhead bin space while maintaining a refined silhouette and lightweight structure.

With a strong recycled polycarbonate shell, smooth 60mm Hinomoto Silent Run wheels and Osprey's ZeroLiner interior system, it delivers premium protection and streamlined organisation in a travel-ready format.

Best For

  • International carry-on travel
  • Business trips
  • Frequent flyers
  • Travellers needing expandable flexibility
  • Coordinated Ozone luggage systems

Materials and Construction (Technology Explained)

63% Recycled Makrolon Polycarbonate Shell

The exterior shell is constructed from high-performance Makrolon polycarbonate containing 63% recycled content. Makrolon is known for its exceptional impact resistance, flexibility and strength-to-weight ratio.

Unlike brittle hard plastics, polycarbonate flexes slightly under pressure, helping absorb shocks from baggage handling while maintaining structural integrity. The result is durable protection for your belongings without excessive weight.

ZeroLiner Interior System

Osprey's ZeroLiner technology eliminates unnecessary interior material layers, reducing overall weight while maximising usable packing volume. By simplifying construction, it:

  • Increases interior space efficiency
  • Lowers overall case weight
  • Improves cleanability with a wipe-friendly surface

It's a subtle innovation that enhances performance without adding complexity.

Aluminium Dual-Pole Trolley System

The ultralight aluminium trolley handle is engineered for rigidity and durability. Aluminium offers an optimal balance between strength and weight, preventing handle flex while keeping the chassis light enough for overhead compliance.

Dual-pole construction improves steering control and long-term structural stability.

Hinomoto Silent Run 60mm Dual Spinner Wheels

Premium Japanese-engineered Hinomoto Silent Run wheels provide:

  • Smooth, low-noise rolling
  • Reduced vibration
  • Improved durability over time

The dual-spinner configuration distributes weight evenly across four points, enhancing stability during fast-paced airport transitions.

Bluesign-approved Divider Fabric

Interior divider panels are made from Bluesign-approved, 100% recycled 210D nylon with PFAS-free DWR treatment. Bluesign approval ensures responsible chemical management, safer production processes and reduced environmental impact across the supply chain.

YKK EYL #10 Zippers

Large-gauge YKK EYL #10 zippers are designed for abrasion resistance and long-term reliability. Their construction resists stress from frequent opening and closing while maintaining smooth operation.

Features

Expandable Capacity (34L + 10L)

Integrated expansion panel increases packing space by 5cm, adding up to 10 litres when extra capacity is required.

Lightweight Hardside Protection

Durable recycled polycarbonate shell offers rugged impact resistance while remaining remarkably lightweight for carry-on use.

TSA-Approved Travel Sentry Lock

The integrated lock secures belongings while allowing authorised airport security access. It eliminates the need for external padlocks and maintains a clean, streamlined design.

Four-Wheel Mobility System

Four premium 60 mm Hinomoto Silent Run dual spinner wheels deliver exceptionally smooth, low-noise movement. The dual-spinner configuration enhances stability and weight distribution, allowing effortless 360° manoeuvrability and upright rolling with minimal strain — even when the case is fully packed.

Dual-Height Aluminium Trolley Handle

Custom dual-pole handle extends to two height settings for comfortable steering and stable control.

ZeroLiner Interior System

Weight-saving interior design maximises packing volume while maintaining structural integrity.

Dual Interior Divider Walls

Roll-away divider panels with mesh pockets allow compartmentalised organisation and secure packing.

Carry-On Compliant Dimensions

Meets most international airline carry-on size requirements (always confirm with your airline).

Ozone Family Integration

Pairs seamlessly with other Ozone travel pieces to create a coordinated luggage system.
