Pros and cons of flannel lined jeans


1.) Softness: Flannel is made of cotton fiber and is brushed on one side to create a soft nap. Therefore flannel lined jeans will feel softer against the skin and will prevent abrasions or rashes. 

2.) Breathability: The loosely knit fabric gives room for aeration and therefore improves the coziness of the jeans. 

3.) Lightweight: Since flannel is usually made with cotton fiber, the material is very lightweight. 

4.) Warmth: Even though the material is all natural, breathable and lightweight, it does provide great levels of warmth while ensuring your comfort. 

5.) Temperature regulation: Since flannel is very breathable, it will not cause over heating or over sweating and it brilliantly regulates the temperature. 


1.) Absorbs moisture: Flannel absorbs moisture and hence flannel lined jeans won’t let your sweat evaporate easily. 

2.) Prone to Pilling: Flannel over the course of time will collect annoying little fiber bobbles all over it’s surface. This will probably cause irritation of the skin as it rubs against the legs. 

3.) Shrinkage: When washed with hot water, the flannel lining of the jeans can shrink.

But it is indeed important to take good care of your fleece lined jeans if you want them to live longer and in good shape as well. 

4.) Cost: Synthetic fabrics are made in factories in bulk and are hence a lot cheaper than natural fabrics. Fleece is cheaper when compared to flannel, but the rate does depend a lot on quality and brands as well. 

5.) No heat loss: The tightly knit polyester fabric of fleece do not allow air to pass through it and thereby prevents any form of heat loss in winters. 

6.) No moisture wicking: Fleece do not retain moisture and therefore the sweat will dry off easily and even post laundry it will be easier to dry fleece lined jeans.
