Shipping of starting packages

For ecological reasons, we consolidate starting packages including T-shirts and send them to the address of the company or branch in bulk, always after the end of the current wave of registrations. It may happen that you receive the T-shirt, for example, after a month and a half after registration.

We send the t-shirts in one package to the address you entered during registration. On the cover of the starting package, the names of all the members of your team approved so far by the company coordinator will be listed. Thanks to GLS, one of the participants from the company/branch, who must be set by the company coordinator, will be informed about the delivery of the package in advance via SMS and will be able to change the place and time of delivery.

You or your company coordinator must always approve the registered participants before the end of the wave. That’s the only way participants will get their T-shirt on time – it will leave the warehouse in the given wave. If you are not sure how your T-shirt is doing, contact your company coordinator.

T-shirt of May challenge 2026

A t-shirt made of organic cotton and with an ecological print from MERCHYOU will be given to each participant registered in the May Challenge, and brought to you by GLS. Please select your size according to the dimensions listed in the size chart below. We recommend washing the T-shirt inside out at 30 °C and do not put it in the dryer.

Please choose the appropriate size according to the table, we do not change the sizes of the t-shirts for logistical reasons. Thank you for your understanding.
(We only change the size if you receive a different size than the one you chose.) Try to exchange inappropriately chosen t-shirts in the company with colleagues or on Facebook groups according to your city.
