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

What is the Helium UL Jacket?

The Helium UL Jacket is an ultralight waterproof shell designed for those who prioritise minimal weight without compromising on performance.

Ideal for a variety of fast-moving pursuits, it delivers reliable weather protection and breathable performance while packing down small enough to carry in your pack whenever conditions are unpredictable.

Its streamlined construction makes it ideal for hiking, trail running, fastpacking and travelling, offering highly packable and dependable protection when the weather turns.

Materials & Technology

Toray Dermizax™ 2.75-Layer Fabric

For dependable weather protection, the jacket uses Toray Dermizax™ 2.75-layer waterproof technology for waterproof, windproof and breathable performance while maintaining an exceptionally low weight.

The jacket features a lightweight 15-denier nylon ripstop outer allowing it to withstand regular use in the outdoors, without compromising packability.

Toray Dermizax™ 2.75-layer technology is a lightweight technical waterproof fabric that offers a hydrostatic head rating of 20,000mm, for reliable, breathable weather protection, whatever the adventure. The jacket's lightweight and protective construction makes it well-suited to fast-paced mountain activities when the weather won't make up its mind.

Features and Functionality

Adjustable Hood

A fully adjustable hood with a wired brim provides dependable shelter from the elements without impacting visibility. The hood can be easily cinched in close in windy conditions, and the peak can be easily reshaped to direct rain and wind away from the face as you're moving fast in the mountains.

Packable Design

The Helium UL Jacket features a highly packable construction to keep weight and bulk to a minimum. The jacket's left-hand pocket doubles as a packaway pocket for convenient storage, allowing it to take up minimal space in your running vest or rucksack when the weather improves.

Waterproof Front Zip

The jacket is fastened with a lightweight, waterproof YKK® AquaGuard® centre front zip for maximum weather protection with minimal bulk.

Secure Hand Pockets

For storage, you'll find two YKK® AquaGuard® zipped hand pockets that offer ample storage for quick access essentials such as trail snacks, a mobile phone and energy gels. The pockets also use waterproof zips to help protect your belongings during downpours and prevent literal puddles in your pockets.

Low-Bulk Cuffs

Shaped cuffs with partial elastic binding around the edges provide a comfortable fit and feel around the wrists, whilst helping to reduce drafts in windy conditions. The partial elastic design makes it easier to access your sports watch on the go or quickly pop a sleeve if you start to get a bit too warm, effectively cooling you down, without needing to undo the main zip.

Reflective Detailing

Reflective logo detailing helps improve your visibility to others in low-light conditions, ideal for early morning and late night missions, especially those with some on-road sections of trail.

Adjustable Hem

The jacket is finished with an elastic drawcord hem to allow you to tailor the fit over various layers and further seal out the elements on windy, exposed routes.
