Eureka Spero 30 Degree Sleeping Bag Gear Review
The Spero 30 is EurekaTents' newest kids on the block. Their new Synthesis technical insulation is pretty remarkable. I'm a big fan of down and the synthetic fibers in this bag are really nice and very compressible for synthetic. Another great feature is that the men's and women's bags can be zipped together for nighttime snuggles.
All in all they are fantastic bags and well worth the price
