prAna Men's Brion Pant - Stretch Hiking Pant with UPF 50

In this review the prAna Men's Brion Pant is assessed as a go-to option for hikers and travelers who want a slim, mobile pant that still protects against the elements. The single biggest reason to buy is the signature Stretch Zion fabric blend, which balances durability with stretch so the pant moves with you on trails and long travel days while offering UPF 50+ sun protection and PFAS-free water resistance.

Key Features

• Stretch Zion fabric: The 95% recycled nylon and 5% elastane mix provides reliable flexibility for full range of motion during climbs, scrambling, and everyday wear.
• Secure zip-fly closure: A zip-fly with button fastening gives a familiar secure closure so the pants stay in place during activity.
• Adjustable waist strap: The hook-and-loop strap at the waist allows a customized fit to reduce slippage without adding bulk.
• UPF 50+ sun protection: Built-in sun protection helps keep skin safe on exposed trails and during long days outdoors.
• Abrasion resistance: Durable fabric resists snags and wear from rocks and brush to extend the life of the pant.
• PFAS-free water resistance: A water-shedding finish helps keep legs dry in light rain or wet brush without harmful PFAS treatments.

Who It's For

The Brion Pant is best for hikers, travelers, and anyone who wants a slim-profile outdoor pant that still lets you move freely; the fabric stretch and abrasion resistance make it suited to day hikes and multi-day travel where light protection matters. Those who prioritize sun protection and a PFAS-free finish will appreciate the UPF 50+ and water resistance.

Shoppers who prefer a loose, baggier cut or who need generous pocket storage should look elsewhere, as several customers note mixed reactions to fit and pocket size. Also, if you need secure zippered rear pockets for travel security, the basic pocket set may feel limited.
