G4 Pro® Pack Collection

Easy Access and Fishy Internal Organization Meets Durable Weatherproof Protection.

Now that winter has come and gone, the time has arrived to gear up and get organized for full day pursuits on the water. Whether it’s drifting dries, stripping streamers or stalking the flats, the months ahead are some of the best for hike/wade enthusiasts. Those who fish on foot know the importance of a quality pack. Finally, after over 4,000 hours of rigorous field-testing, Simms is able to offer a collection of packs worthy of the G4 badge. Available in a backpack, sling, hip and tactical-hip style, the G4 Pro® line is no doubt the fishiest to ever leave Simms HQ. Read more:

So how does a fishing pack receive the honor of falling under the G4 umbrella? According to Simms’ Pack Design and Development team, the goal was to marry the functionality, organization and ease of access found in traditional cut-and-sew packs (Waypoints) with the ruggedness and weather resistance of a welded dry bag/pack (Ex: Dry Creek). The end result is an extremely durable and weatherproof pack that still allows quick and easy access to internal organization.

“Both cut-and-sew and welded dry bags/packs have distinctive pros and cons. We wanted to focus on the pros of each type and bring them into one pack.” Says Simms Pack Designer, Paul Thomas “For example, welded dry bags/packs are great but to retain their waterproof capabilities, you end up having to sacrifice ease of access and organization.”

To achieve quick and easy access, each G4 pack implements a unique opening to the main compartment of the pack. For example, the backpack features a U-Shape Tongue type opening that runs almost all the way around the pack. The hip and tactical-hip utilize a dual zip, peel back style opening and while the sling features a large U-Shape Opening. All of these are easy opening and allow anglers to see all of their gear at a glance instead of having to dig around in one big cavernous black hole.

“There are a lot of dry bags/packs out there that are in fact 100 percent waterproof. However, the majority of these packs are next to impossible to get into while keeping the pack on your body, let alone while your standing in a river. We really wanted to retain a high level of water/weather resistance without hindering an angler from making a fast leader or fly change. These G4 packs function much like our Waypoints line only you have the added ruggedness and water resistance.” Says Simms Pack Developer, Lindsay Vincent

So the question is, just how weather proof are the G4 Pro® Packs. In short, the anser is — very. The G4® Pro weatherproof capabilities stem from strategically placed, internal, critically taped seams. In layman’s terms, this means waterproof seams were implemented in the areas of the packs that are prone to get wet first, such as the bottom of the pack. “We didn’t critically tape the entire pack because again, we wanted to retain ease and speed of use.” Says Vincent “We did however critically tape the bottom of the packs which keeps your gear totally protected during deep wades or from water in the bottom of a boat. Make no mistake, just because the main opening isn’t critically taped, it is still highly water resistant and can easily withstand a downpour of rain.”

After over 4,000 hours of field-testing, it’s safe to say the G4 Pro® line of packs have been put through the paces and reflect the true heritage of Simms — guide tested and guide approved.

“I am where equipment goes to die. Considering this, I was extremely impressed with the G4 packs. Before now, I don’t think I’ve had a pack last an entire season. I’m looking forward to putting my G4 Hip Pack through the wringer next year as well.” – Simms Ambassador/Field Tester/Alaska Guide, Mark Hieronymous,

    Embarrassing for a company such as SIMMS not to proofread their articles. When you don’t know the difference between your and you’re and not catch this fault, it tells me you’re not paying attention to details and leaves me wondering whether your products are not going through proper scrutiny either. It looks very dumb.

    Is the G4 back pack 100% water proof and what’s it like when used in the salt?

    Fishing the tropical flats for 6 hours at a stretch I have some concerns about this pack. First is the black color. Even in the mountains of MT during a summer hike, the pack is going to get excessively warm. On the flats where there is no shade and the fish spook easy I am not a fan of the black. The next issue is a hydration bladder. On the equatorial flats its quite easy to suck down a 100oz of water in a trip. Carrying water bottles is a pain, specially when you are constantly on the move and have only a moment or two between stalks. While the drinking tube port will create an ingress point for water, how about a method of attaching a separate sleeve or even a second non-waterproof compartment for one? So to conclude, to make this Flats wading friendly it would have hydration and be in a lighter color.
