The first-ever base layer made with legendary Spectra ® fiber, this all-around performance crew neck will be the hardest working shirt you'll own. Use it as a base layer for your next alpine mixed climbing outing, wear it alone for warmer sport climbing temps, or use it over and over on your next backpacking trip.

Honeywell's Spectra ® material is performance without compromise. Pound for pound, Spectra ® fiber is fifteen times stronger than the strength of steel. Our knitted fabric is 90% polyester, and 10% Spectra ®. With remarkable tear and abrasion resistance, this tee will defend itself against the roughest of rock and elements your alpine pursuits can throw at it. Despite its durability, this fabric blend is remarkably comfortable with a merino like feel. The natural coolness of Spectra ® and the light weight of the fabric offers excellent breathability and all day comfort.
