What Is The Dry-Tech MRT Fly Box?

• Conveniently dries your wet flies inside the box
  
  
• Eliminates hook corrosion in freshwater & saltwater flies
  
  
• Extends the durability, lifespan, and investment in your flies
  
  
• Waterproof, airtight, rugged, durable lifetime construction

Moisture that becomes trapped inside fly boxes can be damaging to flies. Replacing wet flies in your fly box or fishing in wet or humid conditions can cause hooks to rust and fly tying materials to deteriorate. The new Dry-Tech MRT fly box uses Moisture Reduction Technology (MRT) to eliminate the harmful effects of humidity inside a fly box. Moisture from wet flies that generally accumulates inside is now soaked up continuously by unique absorbent crystals.

Wet flies placed back in the box will dry out completely as the moisture from them is drawn out of the box and away from other flies as well. These crystals also maintain a constant dry humidity level of only 10-15% and protect flies from dampness at all times. This eliminates the deterioration of hooks, thread, fly-tying materials and extends the lifespan of your flies. A Humidity Indicator Test Strip is included with each box to demonstrate the effects and benefits of the MRT Design.

How Does It Work?

The fly box uses environmentally safe, odorless, non-toxic gel crystals that continuously absorb and store moisture in a non liquid form. Recessed inside the lid in a special container, these orange crystals turn color when they begin to reach their maximum absorption capacity which is typically between 5-8 individual fishing days for the Medium MRT box.

An individual fishing day is any one day when flies are used and replaced wet inside the box. The variance in days is related to the number, size, and the water retaining qualities of the flies you use. When the beads turn color, the removable crystal container can be quickly regenerated in a conventional microwave oven. When refreshed, their absorption potential and original color are restored. This regeneration process can be repeated for long term service.

Test Results/Hook Corrosion

A comprehensive test was performed on the Dry-Tech MRT fly box in order to analyze the effectiveness and benefits of the Moisture Reduction Technology design. Tests with both saltwater and freshwater flies were conducted. Below is a reference from that report:

After 16 repetitions of drying the same saltwater flies in the Dry-Tech MRT fly box without freshwater rinsing an evaluation of the hooks by microscope and X-Ray revealed no corrosion.

The Medium MRT Box (6.5"L x 4.5"W x 1.75"D) employs a single MRT crystal container and is ideal for small to medium-large trout flies including midges, nymphs, and dry flies. Dense, rich, puncture-resistant graduated foam and slit foam sections store 100's of flies.

In general, the MRT Container will need regeneration every 5-8 individual fishing days and will probably vary based upon your own personal fishing habits and usage. For extended trips or usage, reusable back-up crystal containers are available. The box is completely waterproof & airtight. Rugged, durable, lifetime construction. Made in USA. $39.95 For complete user information please click on MRT User's Guide

The Large MRT box (8.5"L x 5.25"W x 2"D) employs a double container design for larger freshwater and saltwater flies. In general, regeneration may be required after every 5-8 individual fishing days. This is just an average and may vary based upon the number, size, and the water retaining qualities of the flies you use.

For destination trips, wilderness trips, or extensive use of large freshwater or saltwater flies, optional reusable MRT containers are available as backup replacements. High quality puncture-resistant charcoal slit foam stores 100+ medium to large flies. 100% waterproof and airtight. Rugged, durable, lifetime construction. Made in USA. $44.95 For user information please click on MRT User's Guide

Dry-Tech MRT fly boxes are available from Cabela's, select fly shops, or can be purchased from the online store on our website.

Humidity Indicator Test Strip

A Humidity Indicator Test Strip is included with each box to demonstrate the effects and benefits of the MRT Design. This simple test can be done with a new box and just a few wet flies. For some basic tests and observations relating to the MRT design, please click on Consumer Test.
