Whenever you’re fishing in variable weather (which is quite often in fly fishing), layering is an important part of the sport. Building a layering system that works for you allows you to stay warm, dry, and comfortable on the water. Most people think about warmth when layering but layering can help in warm weather, too, but wicking moisture and keeping you cool and dry. If you’re fishing in a colder freshwater environment, chances are you’re wearing waders. Layering under waders is extremely important. Wearing the right clothes under your waders keeps you insulated from cold-water environments and allows you to fish without being distracted by the weather. After all, that’s what we’re all on the water for… to focus on the fish. 


One of the largest fly fishing gear manufacturers is Simms Fishing Products, a high-tech gear company out of Montana. They’re perhaps most well known for the high-end waders they make that are worn by guides and avid anglers alike all over the world. They also make fishing bibs, jackets, wading boots, and a variety of other gear for fishing and outdoor recreation. Turns out, they’re an industry leader in layering, too. The Simms Fleece Midlayer Bib is one of the best layering systems they make. This bib features abrasion and odor-resistant fabric, a grid-fleece interior, a center front 2-way zipper, and a thermo-laminated zippered chest pocket. Add a host of other features and it’s easy to see why this bib is one of the most popular layering systems in fly fishing today. If you’re an angler who wades and fishes in wintry conditions and icy water, this bib will keep you warm all day long.


If you’re looking for pants only, Simms has a handful of great options. The Simms Fjord Pants are their top-of-the-line cold water layering pant. Specially designed for Steelhead season, these pants feature compression-resistant double-layer fleece and stretch-woven cuffs and stirrups for ultimate usability. These pants are durable, ruggedly warm, and perfect for the avid winter angler. If you prefer something a little lighter, check out the Simms Fleece Midlayer Bottom. These pants still offer warmth, but are moisture-wicking and designed for cool mornings and warming days. This is a great layer for an angler who wants to stay warm in the icy water but doesn’t need the extra durability and warmth of the Fjord Pants


Simms also makes an upper layer that can be worn under a rain jacket or winter jacket during inclement weather. The Men’s Exstream Core Top features a 2-layer weave to trap heat and an athletic cut for a free range of motion. This hoodie also features a hood and neck gaiter to help seal out the cold and keep your core warmer during those chilly mornings on the water. And Simms makes a similarly-styled bottom layer, too, called the Exstream Core Bottom. These bottoms are abrasion-resistant and anti-pill with wicking ankle cuffs to integrate easily with your waders and boots. They’re warm and make a great full body layer when worn with the Exstream Core Top
