30 South Trail RX Sunglasses Summary Review

Bold colours and an unusual, hinged arm were what initially struck me about 30 South’s new Trail RX running sunglasses. Both of those aspects of the design are great and the price is excellent when you factor in the free lens pack with 2 extra lenses..

Targetted at longer distance (trail) runners, the Trail RX delivers comfort on both the nose bridge and side arms where they rest on top of the ears. They grip nicely…but not too much. Add an ultralight 26g weight into the mix and these won’t bounce as you run.

The lenses seem pretty good and clear to me with some good colours and choices that included photochromic or polarised properties to reduce reflected light, adapting quickly to changing light conditions. Handy for the trees, brightness and water ie Handy for those long outdoor trail runs.

Ultra/Trail running seems to be going through a renaissance at the moment and the trendy brigade are getting in on the act, consequently, you need to keep up with appearances. I’d say the Trail Rx have an on-trend, modern look with full-frame support for a medium-sized wrap around lens. The colour combos of frame, lens and arms are ‘bold’ and I normally don’t like that but I do like how 30 South have not gone overboard with boldness and I’d definitely wear these myself.

 

Pros

  • Price
  • Design
  • Interchangeable lenses
  • 2 free, extra lenses! (3 in total)
  • Variety of lens choices
  • Appears durable
  • Great for running
  • A lifetime manufacturer guarantee

Cons

  • Hinge – as always with glasses, the weak point is the hinge.
  • For cycling, I’d prefer a slightly larger lens

30 South Trail RX Contents

You get the sunglasses, a cleaning cloth-cum-drawstring recycled bag and a good-quality, semi-rigid case.

Along with the main lens, there’s also a free spare clear lens and free polarized lens both of which are UV400 to give full UV protection.

30 South Trail RX Specifications, Features & Lens Quality Review

The frames use a flexible thermoplastic nylon (TR90) that is increasingly used in performance sports and hiking sunglasses because of both their light weight and flexibility.

VLT: Visible Light Transmission

All RX Trail lenses are classed as High-Definition Optics (HDo), meet 100% UV400 standards and are either CAT0 or CAT3 (see image to right). Add in some anti-glare and your lens is good to go on the longest trails.

30 South also claim the lenses to be ballistic-grade shatterproof, hydrophobic and scratch-resistant. If you look closely at the specs for the lens construction you can see it comprises 9 layers covering scratch resistance, UV, strengthening and various protective layers including polarizing and UV layers.

They are further classed as wraparound lenses with good peripheral vision. I’d say the frame gives great peripheral vision and the frame/lens combo probably covers 70% of the peripheral vision, so some errant light might get in but not much. I’d say this is about right for running sunglasses but for cycling, I’d prefer more wraparound and more of the peripheral vision covered by the lens.

There are two, more interesting features of the sunglasses. Firstly the open-ended flexible ‘loop’ at the end of the arms sits on top of your ear. This doesn’t provide any kind of noticeable ‘suspension/spring’ but the softer rubbery material is much easier on the ear when worn for extended periods. Bottom line: it’s more comfortable.

Secondly, by squeezing in the nose piece, it rides higher on the nose and creates more ventilation should you need it to improve airflow when sweating and hence better avoid misting up

The frame dimensions are broadly 143mm x x55mm x 130mm as shown in this diagram

 

30South Trail RX Product Options

There are 5 frame colour options as shown above, so that’s a yellow arm+blue frame, a black arm+orange/brown frame and so on.

Perhaps the biggest differentiator with 30 South is a free pair of additional lenses that come in a lens pack. In total you get these 3

  • free non-polarized mirror lens (CAT3, UV400)
  • free grey polarized lens (CAT3, UV400)
  • free clear lens (CAT0, UV400)

For an extra £17 you get a PhotoChromic lens that continually adapts to changing light conditions

Receiving a free polarized lens is unusually good and 30South have to be commended for providing a SINGLE sunglasses solution that will cope with any light conditions even rainy days. The further option for a relatively cheap photochromic lens is one of the best things to add that’s normally something reserved for more expensive trail running sunnies.

Any clue as to where they are made?

company is from RSA which is where they are designed.
i guess they are probably made in SE Asia like everything else these days, I’ll ask.

Confirmed from them, “Made in China”

At least they are honest about it. Know any sunglasses that aren’t? Even the ones that say they are ‘made in italy’ are actually only assembled there, parts are made in China. They just mislead for marketing. Only thing I have found that is not made in China are a few lenses, but still most are. Shame but it is what it is.
