The Big Creek sleeping bag was everything promised and more. I was impressed with the quality construction, the bonus cotton carrying sack (a bit bigger than the included stuff sack), and a few features not mentioned in the website. Plenty roomy for two, and at 6'2" I fit fine.
Don't be shy of the no-stuffing-in-back design. When used with the Big Agnes Air Core pads, it worked brilliantly. There's even a small window sewn in so the pad inflation nozzle is accessible without removing it from the pocket. No sliding around, no falling off the pad, no sleeping bag twisting around your feet.
We were toasty on our first 40-degree night, and this summer-weight bag stuffs smaller than our two previous bags combined. Nice.
One glitch: the drawstring that tightens the hood pulled out in the first five minutes of use. :-( Everything else seems fine and I love this bag too much to return it, so I stitched the drawstring back into place myself.
I recommend sticking with Big Agnes Air Core pads. They're a perfect fit and a quality product themselves. Glad I got 'em.
