Big Agnes Copper Spur UL3 XL 2025

Product detailed description

Now a cult favorite—tents from the American company Big Agnes have dominated the rankings of the most popular tents on all long treks for several years! The new 2025 version

HyperBead™

The main innovation is the use of a new, proprietary fabric treatment technology called HyperBead™. In addition to being free of harmful substances, it offers us a whole range of benefits. Thanks to this innovative waterproof treatment, the tents are lighter, stronger, and more durable. In short, exactly what we want and value in ultralight gear. 

In terms of numbers, according to the manufacturer, tents featuring HyperBead™ technology have the following parameters compared to standard materials:

• 6% lighter 
• 25% higher water resistance
• 65% greater strength

HyperBead™ contains no PFAS or other harmful substances.

Big Agnes Copper Spur HV UL3 XL

The Copper Spur series offers the most space and comfort—it has 2 side entrances and spacious vestibules. It is by far the most spacious lightweight three-person tent we’ve had in our hands so far. The XL version is also compared to the standard version 20 cm longer, 5 cm wider, and 2 cm taller. It’s sure to please all tall folks, because even the legendary Dlouhé Bidlo would be snoring away in this one :) 

Thanks to the short crossbar in the middle of the tent, the side walls of the inner tent are nearly vertical, so you won’t feel like you’re in a submarine. If you want to sleep “under the stars,” you can set up the inner tent on its own. On the other hand, if you want to keep the weight to a minimum, you can use the original “footprint” to pitch just the flysheet on its own, leave the inner tent at home, and effectively try out what it’s like to use a tarp.& The flysheet is equipped with two zipper sliders with a cover flap featuring Velcro fasteners. 

The listed total weight of 1861 grams includes a double-wall, self-supporting structure, enough space for an XL sleeping pad, 11 high-quality stakes, guy lines with line locks, storage bags, and even a “repair kit.” The guy lines are reflective, which makes setup and moving around the tent at night easier.  Complete package.

Setting up the tent

The same applies to setting up this tent as to all Big Agnes tents – the inner tent is set up first; the specially designed poles are color-coded so you can’t get them mixed up. Stretch out the corners of the floor and stake them down; snap the mosquito net onto the aluminum poles. You can therefore use it for sleeping under the stars while still being protected from insects. Drape the waterproof flysheet over the inner tent and orient it correctly—the straps at the corners are again color-coded; at the top, thread a short cross pole into the “pockets” in the flysheet (there are loops that allow this without using brute force), and then attach the flysheet to the poles in several places using Velcro loops—this not only helps ensure proper tension but also significantly increases the tent’s wind resistance. At the point where the pole attaches to the floor, simply clip the flysheet to the strap on the floor using a plastic buckle.

You can either thread the remaining tension points onto the floor tent pegs or run them through the guyline, then tighten the line lock and stake them separately. With a quick glance at the instructions, this goes smoothly and quickly even on the first try. Everything is simple and well thought out. Many details of the tent show that Big Agnes knows what they’re doing—whether it’s the use of line locks or, for example, snapping the mosquito net onto the crossbar and threading it into the pockets in the flysheet. The side pockets come in handy, as does the one near the head for a cell phone, headlamp, etc., and above all, the excellent craftsmanship. When using the original footprint  and setting it up without the inner tent, you’ll achieve an excellent weight of 1350 g!

New packaging

The tent now comes with a nifty compression bag EZ Pack Stuff Sack. Unlike its predecessor, it has a longitudinal opening, making it significantly easier to pack the tent. The stakes now have a dedicated pocket right in the bag. We give this a thumbs-up too!

Overall, we rate the new Big Agnes tent series very positively. Lighter, sturdier, more water-resistant, and at the same time more sustainable and eco-friendly!
