An Update on Inventory

Inventory Update

Like many manufacturers, we’re experiencing unavoidable disruptions to our supply chain coupled with increased demand for our best-in-class outdoor gear from folks looking for new socially distanced adventures. Unfortunately, that’s left some of our most popular products out of stock, which we’re genuinely bummed about. We’re doing everything we can to keep production moving, but some supply issues are simply beyond our control. If there’s a particular product that you’re really after, we encourage you to take these approaches:


Sign up for Back-in-Stock Emails

This is the best way to get notified whenever we receive new inventory. You can sign up on any product page, and we’ll send out an email any time new stock arrives.


Check Your Local Dealers

We’ve tried to keep our local stores supplied as best as possible. On every product page we have a “Find in Store” button for local inventory and a “Find Online” option for our online partners. If we’re out of stock, it’s worth a check to see if they have it.


Shop Early

With the holidays approaching, inventory fluctuations and shipping delays could aggravate the issue. If you’re considering an available product, we recommend purchasing early to ensure you don’t miss out.


At this time we’re unable to share updated timelines for re-stocks on specific products as things are changing quickly and unpredictably. Our customer service team is dealing with a significant backlog of questions, repairs, and warranties that are keeping them busy. As such we encourage you to hold your product availability questions so they can focus on helping others get back outside with their favorite gear!
