How to Choose the Best Material Type for Your Endurance Racing Event

Boulder Bibs offer 3 papers to choose from for your race bibs, each with its own unique qualities. We created this guide with photograph comparisons to help you choose the best paper for your race needs!

Our Paper Options

Boulder Bibs Material Standard

Our standard paper is a fan favorite! This option has a soft feel with no texture, it is slightly more rigid & heavier than Tyvek®.

Boulder Bibs Material Tyvek

Tyvek® is made from high-density spunbound polyethylene fibers making it more textured than our standard material. It has a brushed, opal white appearance.

Boulder Bibs Material Fusion

Our Upgrade bib material is the heaviest, most rigid option. It has a matte finish and more prominent texture.

Quality Comparisons

Material Comparison Standard v Tyvek

For the best quality full-color print we recommend our Standard paper, followed by Tyvek®. Both of these options pick up all colors well and remain vibrant.

Material Comparison Tyvek v Fusion

Our Upgrade paper tends to print less vibrant with more dulled down colors. The white paper fibers will show though darker printed colors like the black and brown in this image.

Material Comparison Black
Material Comparison Color

When comparing color printing across the three paper types, our Standard option provides the most vibrant color spectrum and true deep blacks.

Please note that the colors on the bibs in these photographs are not all the same and are meant to serve as a representation of the print quality.

Tear Test

To test durability, we intentionally attempted to tear our papers and these are the results!

Boulder Bibs Material Tear Test

Standard ripped approximately .25" and could not be torn further, Tyvek® showed some stress but would not tear, and Upgrade could be torn with a little extra effort. All three of our papers hold up well under standard racing conditions.

Our Clients' Picks

Standard is a fan favorite and was our main bib paper for years before we added Tyvek®; standard is used for The BOLDERBoulder. Tyvek® is popular for obstacle races and longer events like The Buck Fifty. Upgrade is the paper IRONMAN® uses and several other triathlons prefer this option.
