In our latest competition, we're offering three readers the chance to win a vintage-style helmet with vegan leather straps designed by Thousand and Poketo.
This competition has now closed. Congratulations to the winners, who are Sheri Darby from London, UK, Dale Arnold from Birmingham, UK and Timothy Reeve from Atlanta, USA.
Urban-cycling brand Thousand have paired helmets in a vintage-style shape with graphic contemporary patterns from lifestyle brand Poketo.
The limited-edition collection is available in three colourways: Colour Blocks, Coral Reef, and Memphis Movement, from which three winners will be able to pick their favourite style.
Both based in Los Angeles, the two brands combined their mutual interest in connecting the local cycling community to create the helmets.
Thousand utilised Poketo's characteristic, abstract prints to decorate its headgear that they claim will also help "elevate your personal style".
"It all comes down to simplicity and quality," explained Gloria Hwang, founder of Thousand.
The first colourway, named Colour Blocks, features two-dimensional cut-out geometric shapes in blue, green, yellow and pink, arranged as a collage on a black background.
Softer, curved shapes overlap in the Coral Reef colourway, where teal-blue and pink freeform shapes sit upon a peach-coloured helmet.
Lastly, Memphis Movement takes graphic cues and its name from Ettore Sottsass' postmodern design group, Memphis. White linear arcs, rods and dots are translated into a pattern that is scattered across the helmet's black base.
Each helmet features vegan leather straps and a magnetic buckle fastening which can be operated with one hand.
Thousand's retro remodel of the convention bicycle helmet is rounded with an upturned lip above the forehead.
A dial fitting-system at the back can be turned to ensure a snug fit for any wearer. Three slots at the top and two at the back of the helmet help with ventilation and cooling.
Thousand integrated its signature PopLock system into the design, which allows the helmet to be secured along with the bike.
Users are able to push out the round emblem found on the right-hand side of the accessory to reveal an opening to pass the bike lock through.
Under the brand's anti-theft guarantee any Thousand helmet stolen while locked to a bike will be replaced for free.
Although vintage in style, the collection is certified under current European and North American safety standards.
The materials and design have been tested against impact, chemical wear, and strap retention in various weather conditions.
Thousand has designed its helmet packaging to be used for transportation as well as for display in store. The brand told Dezeen that creating the dual-purpose boxes has decreased its cardboard usage by over 50 per cent.
Every purchase contributes to the brand's partner 1% For The Planet – an organisation whose members pledge one per cent of their annual sales to environmental restoration.
The Thousand x Poketo collection debuted at LA Design Festival earlier this year – where Dezeen rounded up six studios shaping the city's design scene – and is available to buy online and in Poketo stores.
Thousand was established with a focus on designing safety gear that does not sacrifice fashion, making a helmet "you'd want to wear".
Husband-and-wife team Ted Vadakan and Angie Myung founded Poketo to inject art into every-day lifestyle products. Each of its stores in Los Angeles also holds exhibitions and workshops, free to attend for the local community.
Competition closes 10 September. Three winners will be selected at random and notified by email, and his or her name will be published at the top of this page.
