Five Star Gift Ideas

How about a hang gliding experience package? You could book him a day to learn how to hang glide with a professional instructor or arrange for him to go on a tandem hang gliding flight in a place he's always wanted to fly over. Alternatively, if he already owns his hang glider, you could give him a customized hang gliding accessory or an updated piece of equipment to enhance his flights. You could also arrange for a private lesson or workshop with a renowned hang gliding expert.

Or you can get him a star map with the date when he was born.

“It was such a sentimental and romantic present for my husband's birthday (since he is so into astronomy and the moon on the background). The order came super well packaged, and now it is the gem in the basement :)”
