Lambskin vs. Calfskin ? What?s the Difference? | Pierotucci Leather Factory Blog
Here at Pierotucci we use several types of high quality Italian leather, both lambskin and calfskin included. It’s not a matter of one being better than the other, as both leathers are considered a luxury material, but there are in fact several differences between the two. As a general rule of thumb, we typically stick to using lambskin for leather garments such as jackets and coats and calfskin for handbags, wallets, and other leather accessories. The reason behind this is quite simple. Lambskin is a much softer, buttery type of leather and also much more light weight, easily forming to the body. You wouldn’t want to put on a jacket that weighed you down to the floor, would you? Calfskin however, is a tougher and thicker leather than lambskin, therefore better for handbags because the leather retains its shape more easily. Beyond the idea that lambskin is ultimately best for garments and calfskin for handbags, lambskin is also very insulative and protective, especially for its thiness. It stands up to cold climates better than any other synthetic material, which makes it the obvious choice for leather jackets. In comparison, calfskin is soft (although typically not as soft as lambskin) while remaining highly durable, making it good for harsh conditions and withstanding abrasions. So, the next time your’re out and about shopping for leather, feel the texture of it, look at the thickness, see how heavy it is and soon you will be a leather expert too.

The Differences in Lambskin & Calfskin | eHow
Lambskin and calfskin are known for their soft and supple texture, making them preferred materials for high-quality leather shoes, jackets and other clothing. This extra softness is because both materials are taken from young animals; their skin is more flexible and thinner than that of older animals. For those trying to decide on a high-quality leather purchase, there are some differences between calfskin and lambskin to consider before the purchase is made.

- Besides being smooth and silky, lambskin's main draw is that it is insulative and protective, especially for its thinness. Lambskin is unique among leather in that it is tanned with some of the wool still attached to the skin. Lambskin gloves keep hands warm in cold weather, and lambskin jackets stand up to cold temperatures better than many synthetic materials.
[h=2]Benefits of Calfskin[/h]
- Calfskin products are known for their sheer, almost velvety texture and their high durability even in harsh conditions. Although not as insulating or weather-resistant as lambskin, calfskin is tougher and withstands abrasion better. Calfskin gloves and jackets are perfect for people who come into contact with rough surfaces and gritty environments on a daily basis. Calfskin shoes retain their softness longer than other very soft materials even if used by daily walkers.
The only place this jacket is fitted, is under the arm pit. The pit to pit measurement and waist measurement is slim, the rest is rather loose. That is why no matter how loose the jacket looks around the sleeves, back and shoulders, it buttons up perfectly. Trust me, this jacket was created by logan using specific measurements for how they wanted brad pitt to look. It is obvious now when you look at all the seams on the jacket, that they are all there for a reason. So that each part of the jacket can measure a certain way. Now that we know that the xmart jacket was a logan jacket, we know that every single seam was thought out by logan.
