Fabrics are mainly purchased in Canada, United States and China, it’s produced around the world since the Canadian offer is very limited in textile production and does not fully meet the technical needs of the company to offer you high-performance and sustainable materials.

Indigo Denim

This denim of 10 oz is made of 80% cotton, 18% polyester and 2% spandex in a very rich blue that I adore. Its cotton composition makes it very soft, it absorbs fluids and it’s a fiber that will stretch over time resulting in faster perforations, this material has been tested intensively in order to know its crack point which is located at 6500 km travelled by bicycle.  It should be noted that these data may vary with your saddle type, the way you pedal and the maintenance of your garment must be taken into consideration, which varies from person to person. The tension points during pronounced humidity’s in the matter are at the level of the knees and groin. Its 18% polyester content makes it more durable, allowing it to last as long and makes the fabric a slightly thinner. Its percentage of spandex at 2% which makes it a bit elastic in order to stretch slightly during movements. The dye will decrease with the washing and at first it will tend to transfer on a white saddle and perhaps on your undergarments, this will vary depending on sweating during longer trips or on very hot days, and will eventually stabilize after a few washes

Particular Information

As this material is less elastic than the black denim or the Jodhpur fabric, according to my statistics, for the purchase of a particular size it must be a larger one.  If you take for example a medium in black denim and Jodhpur that are comparable in elasticity, you will have to take a large in the indigo denim otherwise it will be a little too tight for the waist and it will bother you.

Black Denim

This 10 oz denim with a black-on-top effect and white underneath (ideal for color contrast for the ‘turn-up’ hem), will tend to become greyer with time as the dye goes away with washing due to cotton. Compared to the indigo denim it’s a little thicker as it has 82% cotton, this higher rate makes it less durable as the fiber itself stretches over time and absorbs more fluids. According to our tests carried out the puncture point is located at 6000 km by bicycle.  Note, these data may vary since it is necessary to take into consideration your saddle type, the way you pedal as well as the maintenance of your garment which varies from person to person. Its 15% polyester makes it more durable than the norm. Its 3% spandex ratio makes it more elastic and very comfortable compared to the indigo denim. The points of tension during heavy wetness in the material are at the knees and groin level but will be felt less as it is more elastic than the indigo denim.

Denim's care

For the maintenance of denims, it is better to wash it once a week if you use it several times or to put it in the freezer to remove bacteria which reduces the need to wash completely, suspend it for drying as heat burns fibres in the long term. It will be stiffer when dry flat, but it will soften on you in 2 hours. To keep your garment as long as possible, note the tears areas and have it repaired/reinforced if necessary in order to keep it longer.

Wear is inevitable in the long term or in repetitive use because of the importance of cotton in these materials as well as the friction factors on the saddle and the acidity of perspiration.  These materials will last longer in the area with the saddle cut lined with antibacterial, according to tests carried out the lifetime increases by 1000 km on average with this option and the perforations will be located at the edge of the cut, making it easier to repair/reinforced without discomfort.


This material can suit with a more casual outfit or even more chic, it will harmonize with a wider range of clothes in your wardrobe. It is also my favourite fabric, it compensates for the shortcomings in denims. It is made in a special way, the 50% nylon is on the top of the fabric which makes it slightly shiny by its synthetic fiber, on the other hand nylon is one of the most resistant fibers which is excellent for abrasion, signs of puncture and tears are not comparable to denim, no signs of discoloration or tears in the saddle area. The only puncture during the last 2 years of testing with several garments was a hole formed at the corner of a pocket linked to a solidification corner seam, which falls into the category variable depending on your use, your saddle and the way you pedal which cannot be considered recurrent. The 42% cotton is inside which makes it very soft against the skin. The ultimate point of this material is its elasticity at 8% in the length and width which makes it extremely elastic, so it harmonizes very well with any movement without giving points of tension in the knees or groin like denims. Due to its low cotton content it absorbs less fluid without limiting its elasticity which is perfect for hot days or during showers. It also does not fade with washing so the color will remain beautiful what is ideal with blacks. This material is the cream of the cream for its durability and comfort. The only drawback as nylon is a synthetic fiber it will tend to make small balls on top with friction, so watch out for this detail and use a razor to remove them. This phenomenon occurred mainly on the hips, due to the rubbing of the pouches, arms or backpacks, slightly on the cut-out of the saddle because the fabric is more crushed in a sitting position on the bike.

Colors available

Black / Grey

Jodhpur's care

For maintenance, such as our denims wash cold and dry flat to avoid burning fibers with drying. Watch for tears and small balls. The material tends to stretch a little when worn several times, so after a wash it will be a little tighter, but without discomfort.

Basic technical specs

Each garment is adapted according to the cyclist, his movements and needs through the options, the base itself can suit everyone.

The base of pants and shorts

1) The cut is semi-fitted and can be customized for a ‘skinny’ finish for pants and shorts can be adjusted in 3 lengths (short, mid-thigh and knee).

3) The rear is higher to cover the entire area of the buttocks and hips in the leaning position on the bicycle. The size itself lies between the high and low, a high size option is available.

7) A gusset that runs along the inside of the legs is inserted to eliminate any pressure in the sitting position, to give more flexibility without tension and to reduce tear by friction that could damage the garment in the long term.

3) Double back belt loops to stabilize belt wear at this area.

Rear pockets aligned and design towards the sides to keep all personal belongings out of the contact area in a sitting position.

9) The front pocket are deep and in an extensible and very soft material.

Basic options for pants and shorts

5) The basic seams that are found on the front and back pockets as well as the back cut-out can be customize in several colors. For a discrete high visibility touch you can choose the reflective thread.

6) Another option for visibility is the reflective bands in several colours, hidden in the inside hem for pants and on the side for shorts, simply flip the hem to use it when needed.

8) Saddle reinforcement zone and lined with an antibacterial to increase the durability of the garment in this area.

10) An independent u-lock holster. 

11) A d-ring on the belt loop of your choice to hang stuff with a carabiner.
