I have always worn regular briefs as underwear and to sleep in.  I decided to give these a try.  As underwear I don't like them much as they bunch up a bit.  However, I love to wear them to sleep in with nothing else on.  I don't like to wear much to bed and these are great as they are short but not quite like briefs.

Update I recently purchased the 100% version of these&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Fruit-Loom-Trunk-Briefs-Assorted/dp/B000P55S98/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Fruit Loom Trunk Briefs Assorted</a>&nbsp;and I like them much better.  They are lighter weight and not as tight fitting.
