The ideal weight of your boxing gloves depends on your body size and training goals. Here is some basic sizing information based on weight:

For training on a heavy punching bag:

Under 100 lbs (including children): 6-8 oz. boxing gloves

100-125 lbs: 10 oz. boxing gloves

125-150 lbs: 12 oz. boxing gloves

150-175 lbs: 14 oz. boxing gloves

175+ lbs: 16 oz. boxing gloves

For sparring or competing in a ring:

Boxers should go up one size (2 ounces) from their standard training glove weight to ensure the safety of their opponent while sparring or competing. The weight of your glove indicates how much padding there is between your hand and your opponent.

You can also choose a glove size based on your training goals. If you are working on strengthening your muscles and building endurance, try sizing up to train with a heavier glove. Heavier gloves require more effort to lift your hands and punch the bag. If you are working to improve hand speed, try sizing down to increase your output. Professional boxers have several pairs of boxing gloves and change glove size based on their goals.

The AIBA, or the International Boxing Association, is the international governing body for amateur boxing. It is responsible for overseeing and regulating amateur boxing competitions globally. AIBA sets stringent standards and regulations to ensure the safety and fairness of boxing matches.

When a product, such as boxing gloves, is labelled as having "AIBA-approved padding," it means that the padding used in the gloves meets the specific safety and quality standards set by the AIBA. These standards are designed to protect the hands and knuckles of the boxers and to ensure that the padding offers adequate protection during matches and training sessions. AIBA-approved padding is a mark of quality and compliance with the safety guidelines established by the international boxing community. It assures boxers that the gloves they use are suitable for AIBA-sanctioned competitions and meet the organization's rigorous safety requirements.

The primary difference between genuine leather boxing gloves and synthetic leather or vinyl-covered gloves lies in the material used for their construction.

Genuine Leather Boxing Gloves:

Material: Genuine leather boxing gloves are made from real animal hide, typically cowhide, buffalo leather, or goat leather. The use of genuine leather provides durability and a high-quality feel.

Durability: Genuine leather gloves are known for their durability, as the natural fibres in leather are robust and long-lasting. They can withstand intensive use and heavy training sessions.

Comfort and Fit: Leather gloves tend to mold to the shape of the hand over time, providing a comfortable and snug fit. They often offer superior breathability.

Price: Genuine leather gloves are generally more expensive than their synthetic counterparts due to the cost of quality leather.

Synthetic Leather or Vinyl-Covered Gloves:

Material: Synthetic leather gloves are made from man-made materials like polyurethane (PU) or vinyl. They imitate the look and feel of genuine leather but are not derived from animal hide.

Durability: While synthetic gloves can be durable, they may not last as long as genuine leather gloves, especially with rigorous use. Their lifespan can be shorter.

Comfort and Fit: Synthetic gloves may not conform to the hand as well as genuine leather gloves, potentially leading to a less customized fit. However, they often provide a comfortable fit right out of the box.

Price: Synthetic leather or vinyl-covered gloves are typically more affordable compared to genuine leather gloves.

The choice between genuine leather and synthetic gloves often depends on your budget, intended use, and personal preferences. Genuine leather gloves are favoured by serious athletes for their superior quality, durability, and fit, while synthetic gloves offer a budget-friendly option with decent performance for recreational and occasional use. Consider your training needs and budget when deciding which type of boxing glove is right for you.
