Simms just dropped its 2025 spring collection, and it’s a very fly-focused new offering from the venerable, Bozeman-based outerwear brand. The new collection includes a plethora of new gear, but a few items will percolate to the top for most fly anglers. Namely, Simms has updated multiple items in its well-loved G3 line—the G3 Boa boot and an all-new G3 bootfoot guide wader. It is also debuting a brand-new version of its Flyweight wading boot and has unveiled a new saltwater wading boot and a new collection of its Headwaters packs.

Here’s a quick look at some of the new-for-2025 highlights.

Simms Flyweight wading boot

The Simms Flyweight line has proven to be an exceptional addition to the company’s footwear collection in recent years—it’s one of those pieces of gear that compels anglers that own it to go out of their way to extol its virtues to others. Like previous incarnations of the Flyweight boot, the new boot (pictured at top) is designed to be lightweight and comfortable for the anglers that like to log miles — whether along the stream or on the trail on the way there. The new version features a synthetic upper, molded rubber toe protection and Vibram Idrogrip outsoles. The light, lace-up boots feature drain holes to help the boots shed water and keep things light and tight as anglers move between fishing locations or boulder-hop from one spot to another.

Simms Free Salt boot

Simms’ new saltwater wading boot, the Free Salt boot, was clearly built with a nod to the wading striper angler — it’s wader-compatible and built to help saltwater anglers keep their feet warm in chillier ocean environments. The boot is constructed with corrosion-resistant materials to protect against harsh saltwater conditions, and the sole is compatible with cleats and studs. The sole is also non-marking, so they’re boat-safe.

Simms G3 bootfoot waders

Bootfoot waders often get a bad rap or simply overlooked by countless angers. Many anglers have concerns about a lack of agility due bootfoot waders’ built-in muck boots. While there’s no doubt some truth to that, it’s mostly a misconception and whatever loss in agility is suffered, it’s a minor inconvenience compared to the enormous benefits bootfoot waders offer anglers in seriously cold weather, as George Daniel explained recently in a recent article about staying comfortable during winter fishing outings. Simms latest incarnation of its G3 bootfoot waders are constructed with tried-and-true Simms breathable tech, comfortable air-mesh suspenders that won’t dig into the shoulders and a zippered, fleece-lined hand-warmer pocket in the chest. The attached boots are vulcanized rubber and neoprene.

Simms Headwaters pack collection

All new in 2025 is the Simms Headwaters pack collection. The collection’s biggest offering is the Headwaters backpack, a substantive pack made for the hiking angler. The pack is built with durable 630-denier construction with a magnetic roll-top closure and some thoughtful storage options. While the pack itself is water-resistant, it features a fully waterproof roll-top liner that drops into the main compartment with a magnetic closure. The main compartment is secured to the rest of the pack with a hook-and-loop system — it can be removed and turned inside out to dry.

The new Headwaters line also features a new sling pack that, in Simms marketing speak, “divides, conquers and corrals” items contained within. The pack is ambidextrous and, like the backpack, is constructed of water resistant 630-denier Oxford nylon. The sling features a compression-molded “workstation” equipped with a fly patch for easy on-the-water fly changes, and it’s got a magnetic-closure drop-in pocket behind the work station for easy access to frequently used tools, fly boxes or even a phone.

For those that prefer hip packs over sling packs, there is of course one of those, too. The pack’s main compartment features a movable divider for tool and fly-box storage, a compression-molded workstation much like what’s included in the sling, a magnetic drop-in pocket, a water-bottle holder and net carrier on either side of the pack.

Finally, there’s also a new Headwaters chest pack that’s designed to have all your tools and gadgets “front and center,” while also offering ample storage. It’s more than just a chest pack — it also features a backside storage container that might be ideal for a light stuffed-in rain jacket or items that aren’t needed all the time, but nice to have on the water. The front pack features an internal divider, and that new workstation the company has incorporated into the line.

The new Headwaters line also features a pair of new flips, and a new flats sneaker.
