Field-Tested Waterproof Protection for Month-Long Backcountry Trips

The 90L Koyukon is a wilderness-grade, field-tested waterproof duffel built for month-long river hunting and fishing adventures. Caribou Gear engineered it with TPU-sealed, multi-treated core fabric — no PVC — so it stays truly waterproof through real abuse. Backpack straps, fixed side handles, and tie-down points make it practical for bush planes, rafts, and ATVs. An air release valve compresses gear in tight quarters, and reflective logos help you locate your bag in the dark. This is a season-proven, rugged duffel designed for serious hunters.

Dry Gear Or It Doesn't Make The Cut

Dry Gear Or It Doesn't Make The Cut

Most waterproof duffels promise dry gear and deliver soaked clothes after a day in a raft. Caribou Gear built the Koyukon 90L after years of month-long river hunting trips exposed exactly how other bags fail — heavy, bulky, and not truly waterproof as advertised. At Hunt Premium, we don't carry gear we wouldn't bet a tag on, and the Koyukon earned its spot. The TPU-sealed, multi-treated core fabric replaces PVC construction entirely, eliminating the toxic, delicate materials that crack and leak after one hard season. This is a bag built by people who actually spend 30 days at a time in river country.

Compression That Works In Tight Spaces

Compression That Works In Tight Spaces

River trips and bush planes don't offer extra room. The Koyukon 90L includes an air release valve on the side so you can compress your load into tight quarters — a raft cargo bay, a float plane baggage compartment, or the bed of a truck packed for a two-week hunt. Reflective logos help you locate your gear when you're breaking down camp in the dark after an evening hunt. Caribou Gear designed these details from lived experience on the water, not from a product meeting room.

Fabric Built For Real Abuse On The Water

Fabric Built For Real Abuse On The Water

PVC dry bags look acceptable on a store shelf and fail fast in the field — lightweight, toxic, and too delicate for serious use. Caribou Gear rejected PVC entirely and built the Koyukon from technologically advanced core fabric that's multi-treated and sealed with the finest TPU waterproofing available. This isn't a bag that survives one float trip and starts seeping. It's a season-after-season workhorse engineered for the kind of trips where your gear staying dry isn't optional — it's the difference between a successful hunt and a miserable one.

Transport Compatibility

Designed for the real-world logistics of remote hunting and fishing trips.

  • Fits in standard float plane cargo compartments

After many years of month-long river hunting and fishing adventures, Caribou Gear took a new approach to duffel and roll-top bags, putting all gear through extreme tests in function and durability. When it comes to dry bags, they found that other brands were heavy, bulky, difficult to use, costly, and not completely waterproof (as advertised).

They didn’t hold back in making the finest, most durable duffel bag available.

Koyukon Waterproof Duffel Bag 90L made with a fine balance of technologically advanced core fabric, which is then multi-treated and sealed using the finest TPU waterproofing available.

They didn’t want PVC dry bags that are lightweight, toxic, and delicate.

They added backpack-styled shoulder straps and carrying handles to the 40L duffel bag for easy transport. It also has convenient removal features and fixed side handles, which is important at the airport or when getting in and out of a boat or raft. 

The 40L and 70L offer tie-down loops at four locations to securely strap the duffel bag to a boat, canoe, bush plane float, ATV, or motorcycle frame

Also included are side Velcro straps for your accessories, such as a fishing case or tripod, and reflective logos to locate your gear easily in the darkest of nights. Compress your gear in tight quarters (with the combined use of the air release valve on the side). 

Koyukon Waterproof Duffel Bag 90L is pliable in the coldest weather and tropical conditions and super tough. It is designed for hardcore hunters and outdoor enthusiasts. Koyukon Waterproof Duffel Bag 90L offer unmatched performance in the field and stylish looks for everyday use. 

Built to handle environmental extremes, protecting your valuable clothing and gear against rain, wind, and snow.

What’s the difference between PVC and TPU

TPU is known for being extremely durable, non-toxic and remains flexible in cold temperatures. TPU resists oxidation and chemical breakdown, extending the life expectancy far beyond PVC. TPU treated fabric has the ability to withstand extended wear, puncture and pressure damage.

PVC is known to be toxic and not recommended for extended use or food storage. PVC becomes brittle in cold temperatures, easily fades, punctures and cracks.
