The Short Answer
Pump Covers are oversized clothing (t-shirts, hoodies, joggers, etc...) which are typically worn over a gym outfit to obscure one's body at the beginning of a workout. These articles of clothing are designed to be taken off once a pump has been achieved to display one's physique in it's most aesthetic condition.
Why Wear Pump Covers?
Many gym-goers believe there are also functional purposes behind wearing pump covers. The idea is that extra clothing assist in generating more heat during one's workout, which in turn improves blood flow to targeted areas of the body. This improved blood flow consequentially promotes a more intense pump. The increased temperature also boosts sweat production, which further enhances the look of muscles under typical gym lighting.
What Makes a Good Pump Cover?
While almost every gym clothing brand carries pump covers, it is important to consider the following qualities before purchasing a pump cover:
Heavyweight: A good pump cover should be heavyweight, commonly quantified with a minimum weight of 200gsm (6 oz.). The thicker fabric, the more heat it generates.
Soft: Softness is crucial for an enjoyable workout experience. However, it is challenging to produce a soft product with heavyweight fabric. The hallmark sign of a quality pump covers is one that the material is both heavyweight and soft.
Stretchy: An ideal pump cover offers a bit of stretch. This elasticity accentuates the silhouette of muscles as the pump intensifies throughout the workout.
Pre-washed: Cotton is the most common fabric for pump covers, and it's essential that the material is pre-washed. Cotton that has been treated with pre-washing minimizes shrinkage and ensures a proper fit even after multiple washes.
