Renshuu Republic: The Intel

The Gear

What materials are the rash guards?

We donā€™t do thin, flimsy gear. Our rash guards are built from premium, high-density performance fabrics designed for high-friction training. They are moisture-wicking, antimicrobial, and reinforced with flatlock stitching to survive the daily grind.

How is the fit?

  • Rash Guards: Designed for a true compression fit to stay in place during transitions. If you prefer a slightly relaxed feel, size up.

  • Heavyweight Tees: Our 6.78 oz tees feature a structured, relaxed athletic fit. They hold their shape and don't drape like standard undershirts.

  • Hoodies: Relaxed fit, built for pre-training warmups and daily wear.

Shipping & Fulfillment

Where is my gear coming from?

Every piece is designed in Texas and fulfilled through our US-based centers. We prioritize domestic partners to ensure the quality matches the "Renshuu" standard.

How long does shipping take?

Most orders ship within 1ā€“3 business days. Custom-printed pieces are made specifically for you and typically ship within 3ā€“5 business days. Youā€™ll receive a tracking number the moment your gear hits the mail.

Why did I get two different packages?

To get your gear to the mats as fast as possible, we sometimes ship items from different fulfillment centers. If your order is split, you won't be charged extra for shipping.

Do you ship internationally?

Currently, we ship exclusively within the United States. We are working on expanding the Republic to international grapplers soon.

Returns & Exchanges

What is the return policy?

Tested on the mats, built for real training. If you aren't satisfied, apparel can be returned or exchanged within 30 days of delivery. Items must be unworn, unwashed, and in original condition.

How do I start a return?

Email contact@renshuurepublic.com with your order number. Weā€™ll provide the instructions and a prepaid label for qualified returns.

What if my gear arrives damaged?

We stand by our construction. If your item is defective or damaged upon arrival, contact us within 7 days with a photo, and we will make it right immediately.

Care & Longevity

How do I make my gear last?

Treat your gear with the same respect you give your training.

  • Rash Guards: Rinse in cold water after use. Machine wash cold, gentle cycle. Hang dry only. Avoid bleach and fabric softeners.

  • Heavyweight Tees: Wash cold, tumble dry low.

Will the designs peel?

No. We use premium printing techniques that bond with the fabric. As long as you follow the care instructions (especially avoiding high heat), your graphics will endure as long as your training does.

Orders & Discounts

Can I get a custom order for my Dojo or Team?

Yes. We specialize in custom team gear for Judo clubs and grappling teams who want something better than the standard catalog options. [Start Your Team Order Here].

All major credit cards, Shop Pay, Apple Pay, and Google Pay through our secure Shopify checkout.

The Why

What does Renshuu Republic mean?

Renshuu (ē·“ēæ’) means "deliberate practice." We believe progress isn't bought; itā€™s earned through repetition and the relentless pursuit of excellence. We build gear for the work no one sees.
