The Libertad odour-free shirt: The 'most perfect shirt' for travellers?

Sweaty armpits while holding a handrail on a crowded train or being the "smelly one on a plane" can be avoided with a new high-performance shirt that will leave you "completely confident" wherever you are travelling, according to its designer.

Made with a lightweight yet durable "all natural high-performance" fabric with no chemical additives, the Libertad is made using advanced wool technology that creates ultra-fine Merino wool which "inhibits the growth of odour-causing bacteria" and is designed to regulate body temperature while absorbing moisture off the body, leaving you sweat- and odour-free for days wherever you are.

The unique material "efficiently manages moisture" without gathering body odour, while the fiber's natural crimp helps it to recover from any wrinkles and remain crease-free for longer than cotton. Three testers were said to have remained body odour-free after wearing the shirt in a tropical climate for five consecutive days.

The breathable and machine-washable shirt, launched on the crowd funding website Kickstarter this month, is said to feel soft against the skin and can be worn "comfortably" year-round, thanks to tiny air pockets that help keep you cool when it's hot, and warm when it's cold.

Available as either a regular or tapered fit in several colours and sizes, Libertad is also designed to be stain-resistant, fire-retardant and anti-static as well as offer UV protection.

The Libertad is the latest piece of "revolutionary" all-purpose clothing that has been proposed in recent years. Last month, the BauBax, a "Swiss Army knife"–style jacket equipped with enough gadgets for James Bond, claimed to provide everything a traveller might need. Dubbed the "world's best travel jacket", it offers 15 built-in features including a neck pillow, hood, eye mask, gloves, drink holder and multiple compartments that can store full size tablets as well as phones, earphones, portable chargers and a small blanket.

Last year, a multi-pocketed trench for women offered a surprisingly sleek solution to cutting airline baggage fees. Fit with 18 pocket that can carry all of your travel essentials including two mobile phones, a digital camera, an iPad, a water bottle, keys and passport, the SeV Womens' Trench also has a 'No Bulge' design that is said to help users maintain a slim "figure-flattering" line.
