Fantastic pjs- treat yourself

My wife and I love our Dagsmejan jams. I buy them for her and she buys them for me, we love their softness, fit, temperature and moisture regulation. When you spend as much quality time with clothing as you do with pjs, these are a worthy investment.

These summer jammies are superb and she really loves them, as she did with the ‘warm’ version during the winter.
