Welcome to Neptune Mountaineering
Back in 1973, Gary Neptune had a simple idea: fix gear, share stories, and help fellow adventurers get after it in the mountains. What started as a small boot repair shop in Boulder, Colorado, became something special – a space where climbers, skiers, and mountain lovers gathered to trade beta, swap tales, and gear up for their next adventure.

Gary knew that the best gear advice comes from people who have racked, skied, packed, and put it through its paces. So he built a team of adventurers who lived and breathed outdoor life. They weren't just selling equipment; they were sharing hard-won knowledge from countless days on rock, snow, and ice. That philosophy – enthusiasts helping enthusiasts – became the foundation of Neptune Mountaineering.
In 2021, Maile Spung and the Ute Mountaineer family welcomed Neptune Mountaineering into their fold. This wasn't just a business transaction – it was a homecoming. Maile's father, Bob Wade, has been part of Neptune's story since 1976, when Gary fixed Bob’s pack before his expedition to climb the North Face of the Eiger. That connection to community and history allows us to stay rooted while growing to meet new challenges and opportunities.
We continue to honor our rich history while welcoming all and inspiring a new generation of explorers. We seek meaningful outdoor experiences in our backyard and beyond, using that firsthand knowledge to help you gear up for wherever your next adventure takes you.

We cemented our commitment to outdoor access for all with the introduction of Neptune Second Send in 2025, our pre-owned outdoor gear shop. An extension of our community-first mindset and our 50+ year commitment to quality gear, Neptune Second Send offers premium pre-owned gear that saves you money and reduces impact on the outdoor spaces we all love, because great adventures shouldn't break the bank or the planet.
So, whether you're planning your first trip or your 400th, we're here for it all. After decades of serving the outdoor community, we still get excited about helping fellow adventurers discover what's possible. We’re here to ensure everyone feels welcome on the journey, no matter where they're starting from.
