What's the difference between fleece and PUL pad backing?

Updated: Nov 21, 2019

When shopping at House of Callaway, you will usually (stock allowing) have the choice of either fleece or PUL backed pads. A common question we receive is, what is the difference between these two backers and what are the pros and cons of each? This post will explore the answers to these questions.

What is fleece?

Fleece is a very soft, polyester fabric. It is usually used for sports jackets, hats, blankets and other items used to insulate the body. It is fairly breathable and has hydrophobic properties meaning that it repels water but is not waterproof.


- some say it is more breatheable than PUL

- helps thinner pads to hold their shape more

- does not have the issue of 'delaminating' over time like PUL does

- due to the texture of fleece, it tends to stay in place easier than PUL


- tends to be thicker than PUL (although some people feel more secure with a little more thickness!)

- can be warmer in summer

- is not totally waterproof so can be unsuitable for extremely heavy bleeders or those with sensitive bladder issues

What is PUL?

PUL stands for polyurethane laminate. It is a fabric where one side is knitted polyester while the other side has a thin film of polyurethane which has been fused onto the fabric. It is breathable, very thin, lightweight and waterproof.


- very thin and keeps the general bulk of a pad down

- waterproof


- can be more slippery on the underwear as PUL is less textured than fleece

- some say it is less breathable than fleece

- can delaminate over time or with improper care, which decreases its waterproof properties
