One of the things I love to do most in all the world is swim outdoors. And I post about this a lot on Instagram. During the lockdowns I went every day. Now I try to go a couple of times a week.
(1) Get an after-swim dressing gown from Nordbaek (this grey one also comes in navy or aqua) and/or a Sittingsuit (big Danish trend), both from Norse Supply.
(3) Get yourself a tow float from Swim Secure. Best to get the biggest one available.
