Purchased the crusader Amour hoodie. High quality, heavy weight but really soft. They are fast to respond to questions and really fast shipping. Highly recommend.

Terrible

Terrible , delivered to wrong address, then they had no stock . Then they had partial stock and know they are saying my items been sent to a neighbor but no note through the door . A total farce would never order from here again

St Kaizen is a cut above.

Pricing was fair, size was true to listed descriptions, delivery was quick, designs are pretty amazing.

I'm getting their st Michael design tattooed in the centre of my chest at the end of 5/26.

So if I'm willing to put it on my body for the rest of my life, you can determine just what a perfect image it is.

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

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.
