Two Harnesses Built for Active Dogs
If you’re choosing between the NOX Sidus H Harness and the Thor H Harness from Zee.Dog, you’re looking at two daily-use harnesses that share a practical design. Both are fully adjustable, easy to put on, and include two D-ring placements on the back so you can choose where to clip the leash. The main difference comes down to extra features and style.
The NOX Sidus adds reflective material that makes your dog more visible at night — a useful safety upgrade for evening walks or early morning runs. The Thor H Harness is part of the limited Marvel | Zee.Dog collection, so it’s a choice for fans who want a themed look without sacrificing function.
What Each Harness Offers at a Glance
-
NOX Sidus | H Harness: The NOX Sidus H-harness is reflective and easy to spot at night. It is fully adjustable with two d-ring placements on the back. Reflectivity is the standout advantage for active dogs walked in low light. The dual D-rings give you control over leash position, which can help with training or comfort.

Thor | H Harness: The Thor h-harness is part of the Marvel | Zee.Dog limited edition. It is fully adjustable with two d-ring placements on the back. The Thor harness delivers the same adjustable, dual-D-ring design as the Sidus, but in a limited-edition Marvel theme. It’s a daily harness with a collectible twist.

Key Differences to Consider
- Nighttime visibility: The NOX Sidus includes reflective detailing for low-light visibility. The Thor harness does not list reflectivity in the supplied catalog facts.
- Design theme: The Thor H Harness is a limited-edition Marvel collaboration. The NOX Sidus has a non-themed, sporty look.
- Price: The NOX Sidus is priced at USD 13.79 (catalog comparison price USD 19.99), while the Thor is USD 14.69 (catalog comparison price USD 20.99). The Thor costs slightly more, likely due to the licensed design.
- Size range: Both harnesses are available in Extra Small, Small, Medium, and Large. The supplied catalog does not include specific measurements for each size, so you’ll need to measure your dog and consult Zee.Dog’s size guide.
Honest Trade-Offs
Neither harness includes care or washing instructions in the supplied facts, so you’ll want to check the product tag or contact Zee.Dog for cleaning recommendations. The dual D-rings are confirmed on both models, but the catalog doesn’t specify the material or weight capacity, so it’s best to treat them as standard daily-use harnesses rather than heavy-duty gear.
If you walk your dog in low-light conditions, the NOX Sidus’s reflectivity is a practical safety feature that the Thor doesn’t offer. If you’re a Marvel fan or want a unique look, the Thor’s limited-edition design may be worth the small price difference.
