Zippers are the savior and bane of lightweight tents. They work well when they work, and keep weather and bugs at bay easily. Until they go bad. Snagged on their own material, or simply lost metal to metal contact they can be frustrating and impossible to fix.
Here comes Big Agnes with an alternative: the Zipperless Tent, the Fishhook SL2..Replacing the zips with magnets, Big Agnes claims their new fastening system will keep bugs and rain out as well as zippers. Fifteen magnets secure the main door. We tried the system, and while not as quick as a fast running zipper, with a little practice with tucking and aligning the magnets, this does the job and without the fear of catching fabric in the zips.
This 37 square foot tent weighs just 3 lb. 10 oz.
