Saint Kaizen is a Christianity × Gym apparel brand founded in 2022 by Christopher Clarke and Richard Buruiana, two Christian entrepreneurs from Ireland with prior experience in the fashion industry. The name Saint Kaizen combines Saint, meaning holy, with Kaizen, a Japanese term referring to continuous improvement — the pursuit of becoming better each day through discipline, consistency, and faith. Saint Kaizen was created to merge high-quality performance apparel with Christian values, offering gymwear and lifestyle pieces designed to reflect belief, discipline, and purpose. Since its founding, the brand has expanded beyond gymwear into a broader range of products, including detailed cut-and-sew hoodies such as the Crusader Armor Hoodie and footwear releases inspired by scripture, including the Isaiah 41:10 sneakers. In October 2025, Saint Kaizen hosted its first in-person event at Mr. Olympia, led by founder Christopher Clarke, marking the brand’s transition from an online-only presence to live community engagement. Today, Saint Kaizen serves a global customer base of over 110,000 believers, seeking apparel that represents both physical training and faith-driven living. Saint Kaizen — a holy pursuit of continuous improvement.

The shipping was fast and efficient and the quality is amazing this is definitely my new favourite hoodie
An exceptional clothing collection
This store has an exceptional clothing collection. The quality is excellent and the styles are beautiful. I’m very satisfied with my purchase and will definitely shop here again.
Headache. Thank God this is the only product I’m ever purchasing.
Timeline of events spanning from April 3rd-28th…
4/03: I tried to order a duffle bag (that I signed up for emails to receive notification when the item is back in stock & received an email for) - I go to order the item, but the site says it doesn’t deliver to my address (later told because it ‘wasn’t in stock’?) - so, I wait.
4/10: The site lets me order the item - I get a confirmation email.
4/13: I get an email w/ UPS tracking number.
4/16: I email SK because tracking has been sitting on “Last Scanned: Label Created on 04/13/2026” - later receive a reply containing “we regret to inform you that the Soldier of God Duffle Bag is currently unavailable” - I go back and forth with them until settling by 4/17 on me waiting for the item to come back in stock to receive it.
4/28: I have re-signed up for ‘item in stock’ notifications at this point & received the emails/texts - I reach out to them about my item - receive a reply saying “after checking with our warehouse, it looks like the original shipment may have been lost in transit”—when that’s not what they originally said happened…
5/05: finally received my purchase. Happy it’s here but never ordering from them again. What a headache.
P.S. I saw a review (on the same item I ordered) that said they didn’t receive their item, and assume what happened to me, happened to them, but maybe they didn’t reach out to SK. Make sure to keep in contact with Customer Service.
Big fan of Saint Kaizen overall
Big fan of Saint Kaizen overall, the quality and fit are on point. The shorts, in particular, stand out: comfortable, well-made, and true to size. They’ve quickly become a go-to. Only downside is shipping. It takes longer than expected, so you need to plan ahead. If they can tighten that up, it’d be a near-perfect experience.
The product was not oversized.
The product was not oversized.
Your website recommended xl so I got a XXL for a oversize look. Nope, fits like an normal shirt. Not really stretchy. Not the best shirt for the gym. The shipping I was good. The design is nice too. I can already tell the material is gonna shrink
Buyer beware - does not honour return policy
Buyer beware, I second the other reviews about customer service and return policy. Really poor customer service.

Kaizen Hoodie
Super easy order, product was perfect would definitely purchase again!
Crusader Hoodie - First Class Quality
Quality of the garment is top class.
Well made, heavy duty, feels like good merchandise.
Sadly the wrong size arrived. Return postage to the US was costly - make sure you order the correct size.
I'm 6' 2" and 230 pounds - the Crusader XL sweatshirt is top quality but it comes up a little short on my arms and in the body.
If I was ordering again I would order XXL.
Replies to emails do happen, but they take many days - don't expect a speedy answer.
Ordered a second product because love…
Ordered a second product because love the mission behind the brand. Once again the hoodie is an amazing quality that exceeded my expectations!
I really appreciate your communication…
I really appreciate your communication and customer service. Not to mention the message itself and the values your products stand for.
My way to Saint Kaizen
So
Saint Kaizen fell in my eyes through Instagram
As an believing Christian I was interested in their products
I also am a big fan of active gym sessions so I was even more excited to own one of their products
So I bought a hoodie an a pair of wrist wraps since my old one ripped
I love the looking of it and I hope to buy some more products like a belt or something else
One of my best buys
Responsive and helpful when trying to…
Responsive and helpful when trying to exchange sizes
Great quality and fast delivery
Terrible customer service
Terrible customer service, sent my items incorrectly so I incurred a duties charge which I already paid in my initial invoice to them. Couldn't even bother replying for them to correct their error.
