Construction & Materials
The Mettle Singlet 2.0 is made from lightweight 100% polyester interlock material, chosen for its durability and moisture-wicking performance under competition conditions. The diamond weave construction reduces fabric weight and improves airflow, keeping athletes cooler across multiple rounds. An athletic cut supports full shoulder and arm movement without restriction, while the close fit meets the presentation standards expected in amateur competition. Available in red and blue to suit standard corner assignments at junior bouts.
Who Is This For?
The Sting Junior Mettle Singlet 2.0 is designed for male junior boxers competing at club, regional, or national amateur level. Available in sizes from 10 to 16 years, it suits young fighters across age categories from schoolboy through to junior. If your boxer is stepping into the ring for their first bout or is a regular on the amateur circuit, this singlet provides the proper competition presentation their club and coach expect. It is equally practical for inter-club shows, ABA events, and structured sparring competitions.

Construction & Materials
The Mettle Singlet 2.0 is made from 100% polyester interlock — a fabric chosen for its durability, flexibility, and resistance to wear under repeated training use. The interlock weave provides a smooth, close surface that reduces friction and keeps its structure session after session. The athletic cut is tailored to allow unrestricted shoulder and arm movement, which is critical during combinations and defensive work. There are no restrictive seams across the torso, giving the singlet a clean competition silhouette that meets standard amateur boxing presentation.
Who Is This For?
The Mettle Singlet 2.0 suits amateur boxers competing at club, regional, or national level who need reliable ringwear that meets competition standards. It works equally well for sparring sessions and technical training where fighters want a vest that stays in place and doesn't interfere with movement. The singlet is available in sizes XS through XXL, covering a wide range of weight classes and builds. Note that the fit runs oversized — most boxers should size down one size for a closer, competition-ready fit. Coaches and club managers sourcing team ringwear will also find the size range practical for outfitting fighters across different divisions.

Styles and Fit
An essential part of your boxing clothing rotation, a well-fitted boxing vest should allow complete freedom of movement through the shoulders and torso without excess fabric that could bunch or snag.
Our range includes classic singlet cuts with racerback designs that keep your arms unrestricted during combinations, as well as looser-fit training vests suited to pad work and conditioning sessions.
Whether you prefer a traditional white boxing vest or something with a bold colour block design to match your boxing shorts, every vest in our collection is cut with a fighter's proportions in mind.
Tapered waists, reinforced hems and flatlock seams ensure each vest stays in place round after round without causing irritation.
Material and Breathability
Boxing vests are typically constructed from lightweight polyester, moisture-wicking blends or performance mesh panels that channel heat and sweat away from the body. These fabrics dry rapidly, keeping you cool under gym lights or in the ring during intense sparring sessions.
Some vests incorporate compression-grade materials that support the core muscles while maintaining full range of motion. For fighters who train in warm conditions or sweat heavily, look for micro-ventilation zones around the back and underarm areas to maximise airflow where it matters most.
Training vs Competition Vests
Training vests are built for durability first. They endure repeated washes, heavy bag work and long conditioning sessions without losing shape or colour. Fit tends to be slightly relaxed, prioritising comfort over strict regulation compliance.
Competition vests must meet specific requirements set by sanctioning bodies such as World Boxing for amateur bouts. These vests are typically form-fitting with a defined colour (red or blue corner), and they often feature a cleaner, more minimal design. If you compete regularly, having a dedicated competition vest separate from your everyday training kit is essential.
Choosing the Right Boxing Vest
Start by considering your primary use. If you need a boxing training vest for daily gym sessions, prioritise moisture management and robust construction. If you are preparing for competition, check that the vest meets the regulations of the governing body overseeing your bout.
Size is critical. A vest that is too tight restricts your breathing and shoulder rotation, while one that is too loose can shift during exchanges and distract you in the ring. Consult the sizing chart for each product, measure your chest and waist, and choose the closest match. For fighters seeking a personalised look, custom boxing vests are available to represent your gym, club or national colours with precision.

Boxing Vest FAQ
The best boxing training vests are made from lightweight, moisture-wicking fabrics with flatlock seams to prevent chafing. Look for a racerback or athletic cut that allows full shoulder rotation. Durable polyester blends hold up well across repeated training sessions and frequent washing, making them ideal for daily gym use.
Training vests prioritise durability and comfort for everyday gym work, using robust fabrics and a slightly relaxed fit. Competition vests must conform to the regulations of the sanctioning body, such as World Boxing for amateur bouts, and typically feature a tighter, more streamlined cut in the required corner colour.
A boxing vest should sit snugly against the torso without restricting movement or breathing. The shoulder straps must stay in place during rapid arm movements, and the hem should reach the waistband of your shorts without riding up. If you can raise your arms overhead comfortably, the fit is right.
Most boxing vests are made from lightweight polyester or polyester-elastane blends engineered to wick moisture away from the skin. Some feature mesh panels for enhanced ventilation, while others use compression-grade materials for added core support. These fabrics are chosen for their quick-drying properties, durability and resistance to repeated washing.
Yes, amateur competition typically requires vests that meet World Boxing regulations. These vests must be the correct colour for your assigned corner, usually red or blue, and fit closely to the body. Always check with your coach or event organiser for the specific requirements before purchasing a competition vest.
Measure your chest at its widest point and your waist at the narrowest part above your hips, then compare these measurements against the product sizing chart. Boxing vests should fit closely but not restrict movement. If you fall between two sizes, most fighters prefer the smaller size for competition and the larger for training comfort.
