Who is the FLOW 1 layer for?

Agile performance

Use cases and athlete profile for the Single Layer.

Ultra-lightweight protection developed for athletes who need joint warmth and proprioception without feeling restricted, bulky, or weighed down.

HYROX and endurance racing: Maximum breathability and zero bulk to sustain an optimal running pace, transition smoothly through the RoxZone, and fly through high-rep conditioning stations.

High-speed and bodyweight conditioning: Full, unhindered range of motion for fast-paced movements like burpees, box jumps, double unders, and kettlebell swings.

Hybrid and functional fitness athletes: Specifically engineered for those who prioritize absolute freedom of movement, agility, and sweat management over heavy mechanical compression.

Light-load dynamics and wall balls: Ideal for high-repetition metabolic conditioning where maintaining a consistent joint temperature and non-slip performance is critical.

Combinations

Modular System

Configure your support according to the demands of the WOD.

"Adapt your support to your workout". Not every exercise requires the same stability or mobility, which is why you can customize your protection by combining the FLOW textile range and the POWER neoprene range.

Standalone Agility Configuration (FLOW 1 Layer): Absolute freedom and breathability. Ideal for pure endurance racing, high-speed metcons, or hot training environments where heavy compression causes premature muscle fatigue.

Smart Hybrid Configuration (FLOW 1 Layer + POWER 5 mm): Light background compression with on-demand support. Keep the fabric sleeve on for agility during the cardio or gymnastics block, and pull the 5 mm neoprene sleeve up from your ankle only when facing heavy strength sets.

Extreme Lock-in Configuration (FLOW 1 Layer + POWER 7 mm): Maximum structural stability with optimized joint comfort. Overlapping the 7 mm neoprene over the single fabric layer creates an incredibly stiff barrier for PR attempts and heavy squats while regulating joint temperature and protecting the skin from chafing.

Custom Endurance Configuration (FLOW 1 Layer + FLOW 2 Layers): Layered textile compression. Combining both fabric sleeves provides a highly responsive, progressive compression that increases stability during moderate lifts without the stiffness or heat of neoprene.

Frequently asked questions

What is the main difference between the FLOW Single Layer and traditional neoprene knee sleeves?

The FLOW Single Layer is made of an engineered, high-strength stretch fabric instead of neoprene. It provides light support, consistent joint warmth, and enhanced proprioception with maximum breathability and zero movement restriction, making it perfect for high-speed cardiovascular and conditioning workouts.

Can I use the FLOW Single Layer for heavy weightlifting?

While it provides excellent joint warmth and proprioceptive awareness, it is designed for light support. For heavy lifting blocks (loads over 80% of your 1RM), we recommend stacking it with a POWER neoprene sleeve or opting for the POWER range directly to get the necessary mechanical compression.

Does the FLOW Single Layer slide down during intense conditioning workouts?

No. It features built-in anti-slip silicone bands on both the top and bottom edges. This ensures the fabric sleeve stays completely locked in place above and below the knee, eliminating the need for mid-set readjustments even during sweaty running intervals or box jumps.

How does the Calf Anti-Compression System work on a fabric sleeve?

The sleeve is engineered with an anatomical, non-cylindrical shape featuring three distinct diameters to mirror the leg. This design specifically releases pressure on the upper insertion of the calf and soleus muscle during deep knee bends, preventing circulation discomfort and annoying bunching behind the knee.

Is the FLOW Single Layer approved for official CrossFit and IWF competitions?

Yes, the FLOW Single Layer fully complies with both CrossFit and IWF rulebooks. However, keep in mind that official CrossFit competition-stage rules prohibit multi-layer systems on the floor, meaning you must wear it as a standalone sleeve per leg during those specific events.

What are the benefits of using it as a base layer in the VELITES Modular System?

It acts as the perfect foundation. You can keep it on for the entire session to maintain joint temperature and agility, and quickly slide a POWER 5 mm or 7 mm sleeve over it when transitioning to heavy barbell blocks, adapting your gear to the workout in seconds.

How do I choose my correct size for the FLOW Single Layer?

Stand up and measure the circumference of your thigh exactly four fingers above the upper edge of your patella (kneecap). Match this measurement to our size chart. Choosing the correct size based on your quadriceps ensures the anti-slip bands grip perfectly without shifting or cutting off circulation.

How should I wash and care for my fabric knee sleeves?

We recommend hand washing them in cold water with a mild detergent, or using a gentle machine cycle inside a mesh laundry bag. Always air dry them completely; do not use a dryer or expose them to intense direct heat to protect the elasticity of the fabric and the silicone non-slip bands.
