Several months ago I introduced the Big Agnes Copper Spur 2 tent here at Outside San Diego.  You can read that report here The Big Agnes Copper Spur 2 is a lightweight freestanding, double walled tent.  The tent is designed for 3-season use, and the inner wall is primarily mesh,  with a small perimeter  of waterproof coated ripstop nylon extending up from the floor. It is a cozy fit for two, and a palace for one.  The Copper Spur features two doors on each side of the tent with separate individual vestibules. The door are a large “D” shape that for some inexplicable reason zip down, leaving the fabric of the door  bunched up on the  floor to be crawled over when entering and exiting. The DAC poles are made from TH72M aluminum, and are hubbed to create two separate shock corded pole assemblies.  The tent is asymmetrical from the head area to the foot area,  and therefore the fly goes on only one way. Proper alighmeent is  aided by color coded clips on each corner.  After an short learning curve,  the tent set up quickly and without a lot of hassle.  The included stakes are very good,  lightweight and strong.  Like any stakes that try to find the sweet spot between weight and performance,  they do not hold as well as a full sized heavy stake. While the design of the Copper Spur is not revolutionary, the combination and use of materials produces a reasonably sized 2-person double walled, freestanding tent that has a trail weight in the mid-three pound range; makes it a standout among it’s peers.  The fact that this tent is easy to set up, and has proven to be plenty durable adds to the appeal.  I have had the opportunity to use the Big Agnes Copper Spur 2 tent on multiple trips in a variety of different conditions through the fall and early winter.  The tent has seen me through some very significant weather, and has functioned near perfectly.  The Copper Spur 2 proved to be very durable and very weatherproof.  It rained during several outings, and moisture inside the tent was never a problem.  The combination of superior double wall design and quality materials make both external moisture, and internal condensation a mute issue .  The most annoying issue I encountered with this tent was the noise the fly and the poles made while they rub against each other in windy conditions.  I expect wind noise,  but the  low pitched squeak that emanated from where the poles contacted the fly with each gust of wind was annoying.  Fortunately I was able to adjust the tension of the fly using the buckles on each corner, but could never silence the squeak on a particularly windy evening. The Big Agnes Copper Spur 2 is the perfect tent for backpackers looking to lighten their load for a sufficiently sized two person double walled freestanding tent and is willing to trade dollars for ounces.  Big Agnes has a reputation for making high quality gear, and the Copper Spur 2 only enhances that reputation.  I have used the tent extensively,  and it has grown to be one of my favorite.  I reach for it when I am backpacking with another person,  and often when I am sleeping alone, as it is as light as many of my 1-person tents.  The tent has proven to be durable and well crafted, and I predict that it will perform for many years to come.  The $400.00 price tag is steep, but I am confident it represents a good value for a weight conscious backpacker.
