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.

Our Mountaineering Alpine Zone Tents

Our Every Season Tents

    • WindSaber – “One Tent to Rule Them All”
      Outside Magazine

      One tent to rule them all. Best for: a nightout anywhere, anytime, whatever the conditions. …this four-season monster could replace all the other tents in your garage.”

      Modern Hiker

      “Actually lives up to the name ‘all-season’. Strikes the right balance – light, strong, and modular.”

      Backpacker 2017 Gear Guide

      “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.
      True to its name, the WindSaber handled 60-mph gales with ease. ‘The gusts were so strong that they started to pull the stakes out of the ground, but the tent handled it like a spring breeze,’ one tester says”

      Backpacker Magazine

      “TENT REVIEWS: The 12 Best New Tents of 2017.”

      Gear Institute

      “advanced feature set, innovative design, extreme sturdiness”.

Our Backpacking Treeline Tents

  • 2Lite – “as light as anything else out there, much stronger, much more livable and cheaper too.”

    “lighter than our previous favorite.”

    Gear Institute

    “While the 2Lite’s 29 square foot floor area seems small, living in the tent does not.”

    Treeline Backpacker

    “…supremely light weight…an exceptional value and true reliability


    “best for anyone looking for a three-season tent where packability and weight are at a premium: backpacking, bike touring, or thru hiking.”


    “The 2Lite really shines in terms of interior livability.”

  • CrossBow– “One Tent For All Seasons.”
    Trailspace: StormPack

    “minimizes weight, yet still has the strength to stand up to virtually any weather!”

    Trailspace: with Mesh DropIn

    “protected from insects…minimizing weight.”

    Trailspace: Mesh Body

    ” the workhorse configuration of the SlingFin CrossBow 2 family…this tent will stand up to virtually any weather”

    Trailspace: Ripstop Body

    “among the most stable tents I have ever used…in the 30+ mph range this tent did not budge.”


    “light but more importantly…strong, stout, and taunt.”

    Industry Outsider

    “extremely lightweight, yet…strong and comfortable.”


  • Bill Allen, Owner/Lead Guide Mountain Trip International:We’ve been using the BFD and LFD on our
    Everest Expeditions since 2010, and they are still holding strong and look nearly new. 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. The quality of material and construction is well above any other tents
    we’ve used and we are definitely getting our money’s worth out of these tents.
  • Bill’s unsolicited email sparked this section. There’s more to come…we’re going to dig through past email and gather quotes.

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!
