Objective:
The goal of this test was to assess the singlets’ overall weight and how it impacts the runner’s freedom and mobility. A lightweight singlet ensures that athletes aren’t encumbered during performance, maximizing efficiency.

Method:
Each singlet was weighed using a precision digital scale to measure its baseline weight. Additionally, we conducted user-based field testing to determine if the singlet felt cumbersome during long-distance runs of up to 10 kilometers in varying terrains.

Outcome:

• The Adidas Iw6105 Adizero Running Singlet scored highest, with its ultra-lightweight fabric providing an almost “barely-there” feel.
• The Nike Dri Fit Aeroswift Singlet Regular and New Balance Impact Singlet X Large also performed well, though their materials were noticeably thicker in comparison.
• The Amazon Essentials 2 Pack Performance X Large was heavier, making it less ideal for competitive settings.

Objective:
This test aimed to evaluate how effectively the singlets managed sweat by drawing moisture away from the body to keep the wearer dry and comfortable during high-intensity runs.

Method:
We conducted sweat simulation tests in a controlled environment using moisture-absorbing pads and recorded the evaporation rate of water applied to the fabric. We also observed performance during outdoor runs in humid conditions, focusing on how quickly the singlets dried over time.

Outcome:

• The Under Armour Standard Castlerock Black excelled in this category, demonstrating superior sweat-wicking and quick-drying properties even in high-humidity runs.
• The Adidas Iw6105 Adizero Running Singlet and New Balance Impact Singlet X Large also offered excellent moisture control.
• The Amazon Essentials 2 Pack Performance X Large struggled in managing sweat efficiently, leading to noticeable dampness during rigorous activities.

Objective:
To determine how well each singlet allowed air circulation, promoting ventilation and reducing overheating during sprints and endurance runs.

Method:
We measured airflow through the fabric using a custom airflow meter to detect resistance. Further, during outdoor runs in temperatures exceeding 85°F (29°C), testers discussed their levels of heat retention and cooling.

Outcome:

• The Adidas Iw6105 Adizero Running Singlet and Nike Dri Fit Aeroswift Singlet Regular displayed exceptional breathability due to their mesh designs and thin materials.
• The Under Armour Standard Castlerock Black also scored high for its perforated fabric, which allowed consistent air circulation.
• The Amazon Essentials 2 Pack Performance X Large ranked lower as its fabric retained more heat, making it less suitable for hot weather workouts.

Objective:
Comfort testing aimed to gauge how well the singlets fit and whether they caused irritation, particularly during extended use. Factors like fit, seam placement, and fabric softness were considered.

Method:
Testers ranged in body types and sizes and provided feedback after 5K and 10K runs. We noted issues like chafing, restrictive fit, or discomfort from seams or labels.

Outcome:

• The Amazon Essentials 2 Pack Performance X Large and Under Armour Standard Castlerock Black received high marks for their soft, smooth seams and non-restrictive fits.
• The Nike Dri Fit Aeroswift Singlet Regular was less comfortable due to its tighter fit and less forgiving material.
• Minor chafing issues were reported for the New Balance Impact Singlet X Large after prolonged use.

Objective:
Durability tests evaluated the longevity and resilience of each singlet to ensure it could endure frequent washing, exposure to outdoor elements, and regular runs without showing significant wear and tear.

Method:
We subjected each singlet to 20 machine wash cycles using standard settings and tested their resilience in trials that included exposure to sunlight, mud, and physical stretching. Post-testing, we examined the fabrics for pilling, loose threads, or fading.

Outcome:

• The Adidas Iw6105 Adizero Running Singlet and Under Armour Standard Castlerock Black showed minimal change after repeated washes, maintaining their structural integrity.
• The Amazon Essentials 2 Pack Performance X Large performed surprisingly well for its price point, showing only slight signs of wear.
• The Nike Dri Fit Aeroswift Singlet Regular was prone to fabric fraying after extensive use in rugged conditions.
