The Big Agnes Copper Spur UL1 is the pinnacle of ultra light backpacking tents. At 2lb 11oz you get all of the great features of a tent without the weight. The side door access is a big plus and with ample room inside of the tent you’ll be plenty cozy on a rainy day. In contrast to the Fly Creek UL1 the the Copper Spur has a lot more room inside of the tent and a little thicker material used in the rain fly and tent floor. If you are looking for an outstanding backpacking tent that will be great in all conditions this is it.
