Outside is the Sidemen’s new wilderness competition series for Netflix, scheduled to premiere on September 28, 2026. The format sends a group of online creators into the outdoors, where challenges, temptations and strategic choices can affect their chance to share a prize worth up to £1 million. Netflix has confirmed the premise, while the exact release time and availability can vary by country.
What is the Sidemen’s Outside Netflix show?
Netflix’s official description says the Sidemen “drop content creators into the great outdoors” to compete through challenges, temptations and scheming for a share of £1 million. That makes Outside a creator-led reality competition rather than a documentary about the group.
The central pressure comes from the prize pot. Contestants are placed away from normal comforts, while their decisions can put money at risk. The setup gives the Sidemen room to combine survival-style tasks with the social bargaining, misdirection and comedy familiar from their large-scale YouTube productions.
Outside also extends the format the group developed with Inside, but changes the environment. Instead of confining contestants to a controlled indoor space, the new series moves the competition into a forest setting. That shift matters because weather, limited comfort and outdoor endurance can influence the game alongside the challenges created by the producers.
When does Outside come out?
TV Insider lists the series premiere for September 28, 2026, matching the date promoted for the launch. Netflix’s official title page confirms that Outside is a 2026 reality series and hosts the official trailer.
Viewers should still check the Netflix listing in their own region. Streaming services can release titles at different local times, and a title page may appear before every episode is playable in every market. At publication time, Netflix had not provided a universal hour on the public title page reviewed for this article.
Who is in the Outside cast?
The announced contestant lineup mixes YouTube creators, fitness personalities, reality-TV alumni and musicians. Listings for the series name Chloe Veitch, Louis Russell, Matt Morsia, Kaci Jay, Moyo, TheBurntChip, Paigey Cakey, Dani Babes, Heinz Baines, Sara Saffari and Yonna Ray among the competitors.
The Sidemen members are the hosts and creative force around the competition. The group’s established on-camera lineup includes Simon Minter, Ethan Payne, Joshua Bradley, Vikram Barn, Tobi Brown and Harry Lewis. Cast credits and final episode appearances may differ from promotional listings, so viewers should treat the released episodes and Netflix’s credits as definitive.
How is Outside different from a normal Sidemen Sunday?
A standard Sidemen YouTube upload is usually built as a self-contained challenge or travel concept. Outside is structured as a season, giving alliances, spending decisions and consequences room to develop across episodes. It is also made for a subscription streaming platform, not simply uploaded as a weekly video.
The distinction is important for viewers searching for the show. Outside is on Netflix, while the group’s regular challenge videos remain on its official YouTube channels. The Netflix page is therefore the safest place to verify regional availability, episode count and age rating.
The series arrives during a period of change for the group. KSI announced earlier in 2026 that he would stop appearing in future Sidemen videos; our separate explainer covers what KSI said about leaving the Sidemen. Promotional material for Outside should not be used to infer more about his current role than the official credits establish.
What is confirmed—and what is still uncertain?
Confirmed: Netflix describes Outside as a Sidemen-led outdoor reality competition with creators competing for a share of £1 million. The listed premiere date is September 28, 2026, and Netflix has published an official trailer on the show page.
Not yet clear from the public Netflix page: the exact release hour in every country, whether the entire season arrives at once in all markets, and how much the prize changes during the game. Those details are best checked against the episodes themselves rather than social-media speculation.
For viewers, the simple answer is that Outside takes the Sidemen’s creator-competition formula into a wilderness setting and packages it as a Netflix season. The format is familiar enough for existing fans, but the outdoor conditions and longer story arc give it a different pressure point from a normal YouTube challenge.
