“As light as anything else out there, much stronger, much more livable and cheaper too..” ― Gizmodo on the 2Lite

"The tents are set up at high altitude for months at a time getting a massive amount of UV, but aren't falling apart like other tents we've used." Bill Allen of Mountain Trips International

"Strongest - At less than 5 pounds, this four-season double-wall is a windproof fortress that weighs a fraction as much as comparable two-person shelters." Backpacker Magazine on the Windsaber

Who Is SlingFin?

SlingFin was founded in 2012 to develop the best gear for use in the outdoors. Period.

Project one was tents that performed better under high mountain conditions of extreme cold and wind. Based on years of design experience and a core innovation, the now patented Webtruss, the results proved an unqualified success.

From the top of the mountain, SlingFin has subsequently worked on challenges central to backpackers and thru-hikers: weight, strength, comfort and durability. The result have been as witnessed by the reviews below.

Our founder, Martin Zemitis has 30+ years of experience first as lead tent designer at Sierra Designs and then as one of the founders and the tent designer at Mountain Hardwear. He has created and continues to create iconic designs beloved by outdoor enthusiasts.

We view our stellar reviews as a natural outgrowth of our dedicated focus on the needs of our customers undiluted by the demands of marketing niches or corporate quarterly reports. We don’t add gimmicks and claim innovation. We are focused on the deep problems of outdoor equipment design...the ones that may take months or years to solve. We go to market only when we have something worth presenting.

Our primary loyalty is to our customers: outdoor enthusiasts like you pursuing our common passion for this wonderful world of ours.

What was SlingFin's Wefunder campaign?
Wefunder is an investment portal. Prior to 5/16/2016, only investors with substantial asset could invest in startups. The JOBS Act Title III changed that and democratized investing. Wefunder's heart is in making startup investments a viable option for everyday people whether they're founding a business or investing to help it get going. They're helping companies from around the country and investors from around the world understand and utilize the new rules.
SlingFin was one of the first companies companies to utilize their portal. We raised over $100,000 in working capital in an offering that closed in December of 2016. Heartfelt thanks to all our investors and to the folks at Wefunder for all the assistance!
