What's the difference between the Solucell™ Boxer Brief and the LYCRA® ADAPTIV Briefs?
The Solucell™ Boxer Brief is built from Supima® cotton with Solucell™ technology for a lightweight, ultra-soft hand feel. The LYCRA® ADAPTIV Briefs use patented LYCRA® ADAPTIV fabric that dynamically responds to movement, delivering adaptive stretch and shape retention for high-output training.
What is Solucell™ technology and why do we use it?
Solucell™ is a specialized process applied to Supima® cotton fibers that creates a 3-dimensional hollow channel system inside the yarn, improving breathability and moisture management. Blended with spandex, the result is a soft cotton feel with 4-way stretch and quick-drying function.
Are the Solucell™ Boxer Briefs made for training or everyday wear?
Both. A middle dart creates an ergonomic fit, 4-way stretch moves with the body, and an anti-chafe internal bonded seam keeps the brief comfortable whether training, commuting, or moving through a long day.
How do the Essential Crew Socks fit and what sizes do they come in?
The Essential Crew Socks come in two sizes: S/M fits shoe size 7–10, and L/XL fits shoe size 10.5 and up. A Y-Heel stitch locks around the heel, and a ribbed body provides strategically placed breathability.
What makes the LYCRA® ADAPTIV Briefs good for high-intensity training?
The patented LYCRA® ADAPTIV fabric responds dynamically to movement, delivering adaptive stretch and shape retention rep after rep. The 3-dimensional hollow channel construction maximizes airflow to keep the body cool and dry.
How do the Solucell™ Boxer Briefs prevent chafing?
An anti-chafe internal bonded seam replaces traditional stitching at high-friction points. The Supima® cotton with Solucell™ technology adds a smooth, ultra-soft hand feel and wicks moisture away.
How do we care for ASRV socks and underwear to make them last?
Turn the product inside out before washing. Machine wash cold with like colors, and use a clear detergent without synthetic dyes. Do not iron.
Do the Essential Crew Socks come in a multi-pack?
The Essential Crew Socks ship as a pack of three pairs, available in colorways including Black, White, Crimson, and Forest Green, with and without the ASRV logo detail.
