Unit Guide Flex Pro MTB Pants



Unit are an Australian brand founded in 2002 on the Gold Coast, with a range that spans Moto, MTB, and lifestyle. The Guide Flex Pro MTB Pants are the only pants offered by Unit, and have more of a gravity than all-mountain focus due to their burlier construction. 

Materials, fit and features

The Guide Flex Pro MTB Pants are made from 90 percent polyester and 10 percent elastane. They’re a 4 way stretch material and I found the material to be the stretchiest on test. They’ve received a DWR water repellent finish like many of the pants on test, and they use a similar ratchet retention system. Two vertical zipped side pockets work well for your phone and keys. The pants also feature ‘quick dry technology’ and reflective logos, a nice touch for those twilight rides home from the trails. The Guide Flex Pros were some of the heavier duty pants on test at 378 grams in a 32” size. 

On the bike

The material's stretch was put to the test as they were the tightest pants on test. If you wanted a looser fit with these pants, I’d recommend going up one size. In terms of skin feel they feel like a pair of high performance boardshorts. The stretchiness worked well for pedalling, and they worked well with and without pads. While not overly hot or hard to pedal when trail riding,  their additional weight and decreased breathability was noticeable compared to lighter offerings like the Mons Royale Virage or the Fox Flexair pants. The additional material is more confidence inspiring for genuine gravity riding. 

Who they suit?

The Unit pants sit in between the lighter all mountain-oriented pants on test and more gravity-oriented pants like the Royal Apex Pants. There’s more material with the Unit pants but their stretch means they pedal nicely. They didn’t breathe quite as well so they wouldn’t be my choice for trail riding in summer. If you’re after the one set of pants to do it all, including gravity riding, these could be it.
