I was looking for a new pair of budgie smuglers for the pool. With the help of Rebel on-line I found a great colour pattern and the size was perfect. Thanks Rebel
Good fit and great quality. Sizing appears accurate
Good quality- long wearing. Good fit. Excellent for the price.
Took my first swim with these and they meet the expectations for quality and comfort
Can't go wrong with Speedo , good service from Rebel .
It’s a Speedo, nothing more to say. Original and Best.
I've been buying Speedo briefs for years and for years I've maintained the same weight and figure and the briefs have always been size 34 and they have fit me perfectly. This one felt like it was two sizes down. Also John Lewis do not offer a straight forward exchange but I have to return and order a new one. Pay for the new one, wait for refund of the one being returned. Very tedious.
