This shelter is squarely aimed at backpackers, hikers, and campers who prioritize a lightweight kit and are comfortable with non-traditional tent setups. It’s a practical choice for those engaging in activities like bushcraft, kayaking, or hunting where a fast, adaptable shelter is valuable.

Design and Build
The Nature Link Sirius Two employs a classic A-frame or baker tent design, relying on two external supports at each end to create its peaked structure. This single-wall construction is a key factor in its low weight. The primary material is 20D ripstop silnylon, a fabric known in backpacking circles for its favorable strength-to-weight ratio and silicone-coated waterproofing. The manufacturer specifies a 3000mm hydrostatic head for the roof and a more robust 4000mm for the bathtub floor, with all seams factory taped to prevent leaks.
Attention to durability is noted in the reinforced peak and tie-out points, as well as the use of snag-free YKK zippers. The shelter includes a bathtub floor design, where the floor material extends up the sides to help prevent ground moisture ingress. The front entrance features a double-layer system with a full no-see-um mesh door for bug protection and a solid canopy that can be deployed as an awning. Inside, thoughtful touches include two storage pockets and a central point for attaching a camping lantern.
Performance and Features
Weight and Packability
The headline feature is the minimum trail weight of 2.31 pounds. It’s crucial to note that this weight is for the tent body, guylines, and stuff sack only. The included ten stakes and five guylines add to the total packed weight, a point highlighted in some user feedback. The packed dimensions are relatively compact, measuring just over 12.5 inches in length, making it easy to stow in a backpack.
Weather Protection and Ventilation
The silnylon fabric and taped seams form the basis of its weather resistance. The 3000mm/4000mm waterproof ratings are suitable for typical three-season conditions, including rain. Ventilation is a strong suit for a single-wall tent. The large front mesh door, combined with a lower rear mesh panel with a flap, is designed to promote maximum airflow, reducing internal condensation—a common challenge with single-wall designs. The front awning mode provides a protected vestibule space for gear outside the sleeping area.
Space and Livability
With a floor width of just over 51 inches, the Sirius Two is designed to accommodate two standard-sized sleeping pads side-by-side. The 45-inch peak height offers reasonable sitting room at the center of the shelter. The open front design, when in awning or screen-only mode, provides excellent views and a sense of spaciousness, which is a significant advantage over enclosed tunnel or dome tents.
Setup, Support and Ownership
Setup is a defining characteristic of this shelter. It does not include dedicated poles; it requires two trekking poles, hiking sticks, or suitable branches cut to approximately 45-47 inches in length. The process involves staking out the four corners, erecting the two poles/sticks at each end, and then tensioning the peak guylines. The manufacturer also describes the option to secure the peak between two tree branches using a guyline. This versatility is a core selling point for bushcraft and adaptable camping. The product is backed by a standard one-year warranty from Nature Link.
Ownership considerations center on the specialized setup. Users must already own or be willing to use trekking poles. Care instructions are listed as hand wash only, which is typical for technical silnylon fabrics. For more insights on specialized outdoor and tech gear, explore our Tech Gear section.
What Owners Say
Owner feedback presents a mixed but generally positive picture. The overall rating distribution shows a significant portion of perfect scores, with others noting specific drawbacks. Positive reviews frequently praise the tent’s lightweight nature, design versatility, ease of setup, and perceived quality for its price point. One owner specifically appreciated the ability to sleep sideways with the large open mesh front.
Critical feedback highlights the actual packed weight including stakes, with one user noting the tent alone weighed slightly more than the minimum trail weight. The most negative reviews express disappointment with the product’s value, suggesting it did not meet expectations based on years of backpacking experience. There are no widespread reports of material failures or leaks in the available excerpts, but the presence of some lower ratings indicates performance or quality may vary.

Who Should Buy It (and Who Should Skip It)
The Nature Link Sirius-2 is an ideal match for the minimalist backpacker or hiker who already uses trekking poles and wants to leverage them as part of a shelter system to save weight. It’s also well-suited for bushcraft enthusiasts, kayakers, or hunters who appreciate a fast, adaptable shelter that can be pitched in various configurations using natural materials. Its spacious interior for two and excellent ventilation make it a strong candidate for fair-weather backpacking trips where views and airflow are priorities.
This tent should be skipped by campers who prefer the simplicity and convenience of a freestanding tent with included poles. Those who frequently camp in bug-heavy areas without a breeze might find the large mesh front less desirable. Backpackers who demand guaranteed, bombproof weather protection in extreme conditions or those who are skeptical of single-wall tent performance may want to look at double-wall alternatives. For those researching other specific product categories, our Reviews hub offers a wide range of analyses.
Final Verdict
The Nature Link Sirius Two Ultralight Backpacking Tent successfully fulfills its primary mission: providing a very lightweight, versatile shelter for two people. Its use of durable 20D silnylon, thoughtful ventilation design, and multiple pitching options offer genuine value for the target audience. The ability to create a covered awning and the spacious feeling from the open front are significant livability benefits not found in many similarly weighted tents.
However, its appeal is niche. The requirement for external poles is a significant barrier for casual campers, and the mixed owner reviews suggest quality control or performance may not be universally consistent. It is not a set-it-and-forget-it shelter but a tool for experienced outdoors people who understand its trade-offs. When judged as a budget-friendly, ultralight trekking pole shelter, the Sirius Two presents a compelling option worth serious consideration for weight-conscious duos.

FAQs
Does the Nature Link Sirius-2 come with tent poles?
No, the Sirius Two does not include any tent poles. It is designed to be set up using two trekking poles, hiking sticks, or suitable branches that are approximately 45 to 47 inches long. This design choice is what allows it to achieve such a low minimum trail weight.
Is this tent truly waterproof?
According to the manufacturer’s specifications, the tent is made from 20D ripstop silicone-coated nylon with a 3000mm waterproof rating for the roof and 4000mm for the bathtub floor. All seams are factory taped. This construction should provide reliable waterproofing for standard three-season rain, but as with any single-wall shelter, proper pitching and ventilation are key to managing condensation.
How many people can comfortably fit inside?
The tent is rated for two people. The floor dimensions are 84.65 inches long by 51.18 inches wide, which is sufficient to fit two standard-sized sleeping pads side-by-side. It provides a reasonable amount of room for two backpackers and their sleeping gear, with extra space for small items in the interior pockets.
What is the difference between trail weight and packed weight?
The minimum trail weight of 2.31 lbs refers to the weight of the essential components: the tent body, guylines, and stuff sack. The packed weight includes all items sold with the tent, which for the Sirius Two adds the weight of the ten aluminum stakes, five guylines, and the stake sack. Owners should expect the total packed weight to be higher than the minimum trail weight.
