Collonil Leather Gel Review: How Good Is It?

The Collonil Leather Gel is known to be one of the best leather gel conditioners in the market. The reason it’s so well known and why several leather manufacturers such as Furla and Mulberry recommend it is because it’s extremely effective and simple to apply on any leather product. 

In essence, the Collonil Leather Gel is based on natural oils and balms and doesn’t contain any solvents, which are typically harmful to leather. These natural oils help to create a waterproof layer and also enrich your leather’s color.

Collonil Leather Gel

  • Available in 50 ml, 200 ml, 230 ml
  • Creates a waterproof layer
  • Made of natural oils and balms
  • Long-lasting and easy to use

In this review, we’ll be taking a detailed look at why the Collonil Leather Gel is touted as one of the best gel conditioners available. 


Collonil isn’t too transparent when it comes to the ingredients of the conditioning gel. This is mainly because their gel is made of a proprietary formula that is claimed to be non-toxic, harmless, and environmentally friendly. 

However, what we do know is that the waterproofing gel contains the following ingredients:

  • Natural Oils – this help to nourish your leather product and seal moisture. It also helps to replenish the natural look of the leather and provides a waterproof coating. 
  • Balms – these have a similar effect and help to create a waterproof coating. Additionally, natural balms tend to bring out the natural colors of leather and also ensure that it’s well protected. 

Benefits & How It Works

Using the Collonil Leather Gel has many benefits. In essence, the gel helps to protect your leather products against the elements and increases their longevity and appearance. 

Here are some of the main benefits:

  • Creates a waterproof layer 
  • Protects against the elements
  • Restores natural appearance
  • Promotes a gleaming look
  • Preserves leather’s condition

Apart from waterproofing, the Collonil Gel also nourishes your leather with natural oils and balms, making it not only last longer but also look better. It does this by deeply penetrating the pores so that the gel is fully absorbed by the leather. 

The natural oils in the gel also help with rejuvenation, by softening the leather and creating a protective coating to avoid water moisture accumulation.

Who It’s Made For

The Collonil Leather Gel has many applications, as it works on any type of leather and also any type of leather product. This means it can be used on nubuck, suede, top-grain leather, full-grain leather, printed leather, bonded leather, split leather, coated leather, and much more. 

This gel is also compatible with all types of leather products, for example, leather gloves, shoes, jackets, belts, bags, purses, pouches, sofas, seats, handbags, or anything else you can think of. 

We use the Collonil Leather Gel regularly and apply it to products that are often in contact with the elements and that are used in unfavorable weather conditions. 

Using this gel is great to protect your leather products against:

  • Moisture (tropical and humid regions)
  • Water (rain and ocean)
  • Snow (winter)
  • Direct sunlight

These weather conditions typically dry out your leather products over time, as both water and sun remove the natural oils from the leather. In the worst-case scenario, this can also lead to leather discoloration or surface cracks. 

Therefore, protecting your leather with conditioners such as the Collonil Leather Gel is generally a good and effective way to not only restore and rejuvenate it’s condition, but also to protect it long-term. 

We’ve used this product for several years (alongside other great leather conditioners) and it’s worked wonders so far. 

Product Sizes

Collonil has plenty of leather conditioning products available and their classic gel comes in three different sizes, which are:

  • 50 ml (1.69 oz) – jar with lid
  • 200 ml (6.76 oz) – bottle with pump
  • 230 ml (7.44 oz) – bottle with pump

All sizes contain the same gel, meaning that the ingredients are exactly the same, regardless of size and appearance. The only difference between the sizes is that the 50 ml version comes in a jar with a twist lid, whereby the 200 ml and 230 ml versions have a pump dispenser. 

The best Collonil Leather Gel size depends on your needs. If you have plenty of leather products, then the larger bottles would have a better cost-value ratio.

However, you may want to be careful when operating the pump dispenser of the 200 ml and 230 ml bottles. Sometimes they can break off during transport or improper use. Therefore, simply be mindful and use it gently.
