The stars of Manchester United will keep their cool with a game-changing high-tech jacket.
Ruben Amorim's team had their first public session from their American tour on Soldier Field, the home of the Chicago Bears.
And despite the temperature in the north of the US that were somewhat immersed after a “real feeling” of 42c at the beginning of this week, the United players were instructed in wearing the silver jackets.
The head of the physical performance of United, Ed Leng, explained the players to the benefits of the new equipment, with First Team -Lead physical performance coach Charlie Owen operated as an unlikely mannequin.
Amorim's players watched with a mix of bewilderment and laughter, but it was explained that the equipment would help them deal with the oppressive heat.
The intention is that the United players will set them up after warming during their Premier League Summer Series matches, starting against West Ham in the Metlife Stadium of New Jersey on Saturday and during the break.
The jacket, developed by Adidas, is tested by United as part of a large breakthrough in cooling strategies and technology.
It is part of what Adidas says is a continuous innovation strategy to constantly maximize performance.
A version has already been used by F1 drivers and cyclists, used to working on extreme heat, keeping the insulation material players cool while they train.
Heat limitation problems are an increasing requirement, demonstrated after Chelsea -Baas Enzo Maresca said that it was “impossible” for his players to train well in the early stages of their successful Club World Cup -Run.
Dortmund and Bayern Munich replaced themselves in the dressing room during some of their games instead of roasting on the couch.
Adidas, long -term partners of FIFA, also expects the jackets to be common among teams that play in next year's world cup.
