Julbo Aerolite Long Term Review

I seek out gear that I can wear into the backcountry without need to stop and adjust as the conditions change. Sunglasses are no exception, and Julbo gets it. All of their sunglasses that I’ve used are well-designed for demanding conditions and users. The Aerolites are no exception.

It is almost too easy to forget that my Julbo Aerolites are on my face––both because they are extremely light but also because the photochromic lenses change light transmission so smoothly and quickly. The frameless design, premium materials, and minimalistic temple design with the “Air Link” system make these glasses featherlight.

  • Panoramic view – the field of view is huge and the frameless design means that as you fly down a technical trail, there are next to no blind spots to trip you up
  • REACTIV Performance photochromic lenses – the lenses will transition under different light conditions. Click here to learn more. You can also get them with a non-photochromic Spectron 3 lens for a bit less money
  • Superior venting – the glasses have huge venting cutouts and sit far enough from my face that I’ve never had them fog up, even on long ski trips
  • Weight – 22g

Style & fit:

The Aerolites are marketed by Julbo as sunglasses for runners with smaller faces, but I have a pretty average face, and I think they fit great. For the massive-glass style that’s popular these days, especially among cyclists, you might look to the larger cousin of the Aerolites, the Aerospeed.

I’ve used the Aerolites in a wide variety of conditions from full alpine sun to snowy ski mountaineering races to night running with a headlamp. Yes, that’s right––these are sunglasses you can run in at night, great news for those ultrarunners out there.

All in all, I’ve put in over a thousand miles with these sunglasses on. They show limited wear and perform as well today as the day I got them. I’ve never had fogging problems, and I’m impressed with their durability, having dropped them on trails, shoved them into stuffed packs, and probably sat on them a time or two.

Final thoughts:

The Aerolites are part of a family of Julbo shades that started with the Aero—a very similar, but slightly larger pair of glasses—and the still larger Aerospeeds that I mentioned before. It would be hard to go wrong with any of these, but I have to say, despite the trend, bigger is not always better, especially for runners. The Aerolites may be the last glasses you ever need.

From Julbo, the Aerolites retail for $219.95 with REACTIV lenses. They come with a hybrid hard/softshell case and microfiber bag. You can likely find them elsewhere for less. I wrote this review entirely of my own accord, and I have no relationship to Julbo other than being a customer.

La Sportiva Bushido II Long Term Review

In Japan, Bushido refers to the code of samurai. Japanese warriors held values of loyalty, frugality, courage, and honor until death. So far, the Bushido IIs live up to their name.

Here are my Bushido IIs after 500 miles. Not too shabby, eh?

When I look for shoes, the traits I look for first are high build quality and durability, moderate to aggressive tread, stability, and foot protection for technical trails. I like to try lots of different drops, stack heights, and footbed shapes, so not a fundamentalist here.

In terms of build quality, the Bushido IIs are excellent. I’ve put 500 trail miles on my pair, and they have performed well and show wear, but remarkably little. In ten years of trail running, I’ve had few shoes hold up so well. 

  • Outsole: La Sportiva’s FriXion XT 2.0 with their impact brake system. For more info about La Sportiva’s outsole types, shoes, and other technologies, click here
  • Midsole: 4mm EVA foam with a 1.5mm rock guard in the forefoot. 
  • Upper: mesh laminated with thermal adhesive microfiber, ripstop, and a TPU toe cap & mid-foot wrap that provide excellent protection
  • Drop: 6mm with a 19mm stack on the heel and 13mm on the toe
  • Weight: 10.5 ounces for mens 9

There are a few worn-spots worth noting. One of the plastic stability control inserts cracked after about 300 miles. The EVA midsole wore hardest under the rear of my arches directly behind the midfoot TPU wrap and similarly the outsole wore hardest right under my arch where the midfoot wrap goes under the outsole.

In terms of fit, the Bushido IIs, like the original Bushidos, have a more narrow, low volume fit, and the last is what La Sportive refers to as their “racing lite ergo.” I have pretty average size feet, and I found the Bushido IIs to fit quite comfortably, though I did size up half a size based on recommendations, which was a good idea. 

The toe box is relatively narrow. When I first saw them, I thought I would be uncomfortable since I usually like a wide toe box, but I found these astonishingly comfortable, and hence they became my go-to for a couple months.

Verdict: great shoes, buy them and then buy extra pizza & beer since they’ll last you a few weeks longer than most other shoes for the same price.

The Bushido IIs cost $130 retail.  

I wrote this review completely of my own accord. I bought the Bushido IIs myself and have no association with the company otherwise.
