YMMV Review

Having recently done a review of the Adidas Terrex Gore-Tex Active Shell Jacket, I wanted to do a review of the Terrex Fast Sunglasses as well. They originally caught my attention because of the cool styling with interchangeable lenses and integrated foam pad. These sunglasses seemed like a good option for winter recreation and I was able to get a pair to test from Adidas.

The Whole Kit


I tested the Terrex Fast Sunglasses across a variety of activities. Not one to focus my efforts in one thing, I rode, ran, skied, snowshoed, and hiked in these sunglasses.

The Adidas Terrex Fast Sunglasses are built to adjust. The sunglasses have a variety of features to make them more than a one-trick pair of sunglasses. The frames of the Terrex Fast are made of SPX material. SPX is lightweight, flexible, and break-proof for better durability. The sunglasses come with two lenses that differ depending on what color frame you choose. The lenses are Vision Advantage PC Lens made from polycarbonate that incorporates a nanomodified water-repellant scratch-resistant coating. The special multi-layer construction makes the lens highly scratch resistant, ensuring a long product life and withstands high impact forces. The lenses are made with the 8-base decentered view for optimum optical quality.

With Head Strap Attached

The Terrex Fast sunglasses feature quick-release hinges. These hinges are designed to release under pressure to protect the sunglasses from breaking. They ae easy to reinstall and also switch out with the included adjustable strap. This strap is a good option for times when losing your sunglasses is not and option. The adjustable elastic strap can be used to completely secure the sunglasses to your head or even over a helmet. The hinges also feature a TRI FIT adjustable temple. The temple has three height adjustments to give you the fit you are looking for. The nose pads are also adjustable. There are two positions available depending on preference. To further adjust there is a quick-shift foam pad that can be inserted without having to adjust the nose pads. This foam pad help make the sunglasses into a semi-goggle. The foam pad has ventilation built into it to help it reduce fogging. Both with and without the foam pad, the sunglasses are RX compatible.

The Terrex Fast Sunglasses come with a hard case, soft sunglasses bag, extra lens bag and everything else described above. The only drawback of the sunglasses is that I am unable to find any reference to the use of sustainable materials of green manufacturing processes. For this reason, I gave them a zero rating for sustainability.

Fit ★★★½☆

Adjustability (50%) ★★★★½

Comfort Next to Skin (50%) ★★½☆☆

It is a bit difficult to address the fit of sunglasses. The Terrex Fast sunglasses are on the larger size. Since I have a smaller head, the sunglasses did feel slightly large on my head. They looked even larger in pictures. The sunglasses do cover a large area of my visual field. Since they are a bit large on my head, I am able to look to the sides and see some gaps between the sunglasses and my face when using the foam pad. I wish they were slightly smaller, so they may be used as a mini goggle. The adjustable nose pieces are nice in that I can either adjust the sunglasses to sit slightly high and off my face or lower and closer depending on what level I adjusted the nose pads too. The pads are made of a rubber type material which is comfortable on the nose even when wearing these for long periods.

Without the Foam Pad

The adjust able temples are really cool. You can adjust these to three different positions, and it really does change the orientation of the sunglasses. If you happen to have ears of different heights, this feature will be much appreciated as they can be adjusted separately. For me, the foam pad helps the sunglasses fit my head better. Without the pad, it is really easy to see how large these are on my head. With the pad installed they fit closer to my face and are more comfortable. The foam material is soft and helps distribute some of the pressure around my face. On the bottom of the temples is a grippy surface to help keep the sunglasses in place. If you really need them to be secure you can use the elastic head strap. This is adjustable to your preferred fit.

Performance ★★★☆☆

Versatility (30%) ★★★½☆

The Terrex Fast Sunglasses come with two lens options. These lenses differed depending on the frame color you choose. I tested out the white and lime frames, and they came with the Space and LST Bright Antifog Lens. The Space lens is a dark lens made for high brightness conditions such as water or snow. The low-light lens is a higher contrast lens for cloudy and foggy days. I found that both lenses were clear and crisp and found no issues with optical clarity. The lenses are an easy and quick change. It is difficult to do it without getting any finger prints on them. Fortunately, the included lens bag and soft bag are both made to clean the lens. At least with this system the lenses are very secure and do not feel like they will fall out. When wearing the Space lens I did occasionally have issues with fogging but had no such issues with the Antufog lens.

With Foam Padding

I did a majority of my testing with the foam pad inserted. For me this was a better fit. I like the comfort of the foam pad and did not have any increased fogging foam pad inserted. It seems to vent well, and it probably helps that they are not entirely snug to my face as this creates a couple of other areas for the sunglasses to vent. The foam pad does help the sunglasses create a bit of an internal microclimate. It also can keep sweat out of you eyes on high intensity days. I liked the foam pad most on windy days. Whether this was a windy day on the mountain or wind while riding my bike. The sunglasses do not allow the uncomfortable venting you get with some other sunglasses.

Changing out the temples is really easy. You can pop them in and out in a second or two and switch to the strap just as easily.  The adjustable strap is easy to use and can be adjusted to a wide range of sizes.  The lens and frame are made of high-quality materials that have some flex to them but also feel really durable. The only part I always worry about is the temple hinge. These sunglasses have a different hinge mechanism and while I have not had any issues yet, I will keep you posted if I do.

Overall ★★★½☆

Overall, I have really liked these sunglasses. They are a larger fit so if you prefer a larger sunglass, this is a good option for you. For me, they were slightly big but with the foam pad this was not as much of an issue. The adjustable nose pads, temples, and lenses make these sunglasses great for a wide range of activities. This makes the purchase of these a better investment as they can be used for all your activities, not just one. I found them to be good for all my activities. I wish you could change the lens without getting fingerprints on them. At least, the included soft bags are made to clean the lens. It is really easy to do but does take a couple of extra seconds when making the switch. The added case is nice and solid. If you need a pair of sunglasses that can be used for everything, this is a good option. Just remember they are on the larger side. The Adidas Terrex Fast Sunglasses retail for $210 but offer much more adjustability than some others in this price point. As always, your mileage may vary.
