The fit guide Men's Underwear

At F&F we believe that a pair of well-fitted, comfy underwear is the first step towards a great day. Here's how to choose your perfect pair.

In new fabrics for the season, many of our trunks, boxers and briefs now feature As New technology, which is designed to prolong the life of the garment, keep the colour longer and reduce bobbling.



F&F trunks team a close fit with a soft brushed waistband for a balance of support and comfort. A front keyhole opening to completes the functional, day-to-day feel.

#2 Hipsters

Similar in style to our trunks, F&F hipsters offer slightly more support with a shorter leg length and front pouch. Made from stretch jersey to ensure a comfortable fit, they're finished with a soft brushed waistband.

Jersey Boxer Shorts

Loose and relaxed, F&F jersey boxer shorts have a touch of stretch and feature a practical button opening at the front. A soft brushed waistband completes this comfort-first fit.

#4 Woven Boxer Shorts

Our woven boxers are our loosest, least constricting fit. In woven cotton for an authentic, classic finish, these boxer shorts come with a functional button opening and soft brushed waistband.

#5 Slips

Sitting naturally higher on the leg, our slips are closely-fitted to offer maximum support. Made from stretch jersey for comfort, F&F slips are available with either a tunnelled or brushed waistband.

#6 Briefs

With a supportive shape and in comfortable stretch jersey, F&F briefs are similar to our slips but with a practical keyhole opening instead of a front pouch. They are also available with either tunnelled or brushed waistbands.
