There are rigs that can be rented for a price of 100SEK/jump. The fee includes an altimeter.
Student rigs can also be rented given that no student is in need of one. When renting a student rig you will receive a packed rig, and you are required to repack the rig before returning it.
Since there is a limited number of rental equipment it is a good idea to start looking for your own gear as soon as you approach the end of you course. Your instructors can help you with tips on what is suitable for you and which rules apply.
