Hints and tips for the most beautiful season.
Exclusive seating
With this app, you can find and book free seats in approximately 3000 private jets and helicopters worldwide – often even cheaper than business class tickets (free for iOS and Android, jetsmarter.com).
Bye Bye Chargers
The electric folding bike with 250-watt engine recharges the integrated battery while riding – thanks to a kinetic energy recovery system (2900 euros, vello.bike).
Glasses for the ears
Bluetooth sunglasses transmit music from the phone by bone conduction into the inside of the ear. Traffic noise remains audible and your hands are free for cycling or climbing (approx. 100 euros, zungleinc.com).
Magic away sand
With this beach mat, the patented fabric structure ensures that troublesome sand from the surface is simply transported through several layers to under the lying surface (about 45 euros, cgear-sandfree.com).
Safe sunbathing
Sunscreenr uses UV cameras to show which skin areas still need sun protection. Creamed areas appear dark coloured, clear areas remain light (approx. 100 euros, sunscreenr.com).
Barbecues made easy
The charcoal grill made of stainless steel in laptop size (29.5 x 19.3 x 2.5 cm) is set up in one minute and with a weight of about 3 kg the ideal excursion companion (98 euros, 
fennek-grill.de).
Cool basket
Do you really want to forgo cold drinks or ice cubes at a picnic? With the Cool Pick Teamstar you don’t have to – thanks to the 10l cooling unit and the compressor-driven 1.7l ice compartment everything stays cool (Price on request, pmc-mobilekaelte.com).
The mountain is calling
