The training tank that runs cooler than cotton. Feels better than anything in your wardrobe.

The TWL HaloFlex™ Oversized Muscle Tank is the tank you put on once and immediately start recommending to people. Built from TWL's proprietary HaloFlex™ fabric — a 75% Polyester / 18% Lyocell (Tencel™) / 6% Spandex blend developed in-house — it delivers a cool-touch feel, a silky drape, and a softness that standard cotton and polyester blends simply cannot match.

Sleeveless, open-armhole, and cut for complete upper-body freedom. Wear it to train, wear it out, wear it everywhere. Once you've worn HaloFlex™, going back feels like settling for less.

HALOFLEX™ — WHY THIS TANK FEELS DIFFERENT:

The secret is the 18% Lyocell (Tencel™) — and it changes everything about how this tank wears.

Lyocell is a natural fibre derived from sustainably sourced wood pulp. At the microscopic level, Lyocell fibres are smooth and uniform — they lie flat against the skin rather than creating the micro-friction that makes standard tanks feel rough after a long session. This is what gives the HaloFlex™ Muscle Tank its distinctive silky, fluid drape — the fabric moves with the body rather than sitting on it.

Lyocell also absorbs and releases moisture more efficiently than polyester or cotton — drawing heat away from the skin during training and releasing it through evaporation faster than standard fabrics. 

SLEEVELESS — BUILT FOR MAXIMUM FREEDOM AND AIRFLOW:

The muscle tank cut adds two things the T-Shirt doesn't have: total shoulder freedom and maximum airflow. The open armhole design removes any fabric from the shoulder and armpit — the two contact points where standard sleeves restrict overhead movements and trap heat during intense training. 

Combined with HaloFlex's natural thermal regulation, the open construction means this is one of the most breathable piece in the TWL range.

SUSTAINABILITY:

The Lyocell in HaloFlex™ is produced through a closed-loop manufacturing process that recaptures and reuses 99% of the water and solvent used in production.
