Outdoor Research Crocodile Review

The Outdoor Research Crocodile is a single-minded model. They're a little heavy and stiff, but they do their one job incredibly well. They are ultra-durable, waterproof, fit over your clunky double mountaineering boots, and are stiff enough to keep themselves from sliding down the back of your calves every other step. For everything else, they are a little too bulky, too spacious and too heavy. At a solid 10.2 ounces a pair, these gaiters weigh a lot.

Comfort & Breathability

Out of the plastic, these gaiters are stiff and a little clunky, and they stay that way for quite a while. The long break-in period is a little annoying but won't cause too much discomfort. The real downside to all the beefiness and durability is the loss of breathability of the fabric. A perfect recipe for super wet and miserable feet is a combination of warmish weather, double plastic boots, thick pants, and these gaiters. Our Editors' Choice winner, the Rab Latok Alpine, uses breathable eVent fabric throughout and is a much better choice than these gaiters for moderate weather mountaineering.

Debris Protection

The gaiters work well at keeping debris out of your boots, but you have to be using them for the right thing. They are meant to go over bigger boots, which doesn't necessarily mean doubles, but using them with smaller shoes leaves a gap that debris can penetrate. They do not fit as well over hiking boots and do not really work at all with approach or running shoes. They are stiff enough to support themselves and keep from sliding down your calves and have a cinch at the top that holds fast and keeps the snow out from above if you are on foot and it's really that deep (seriously, get some skis). They hold snugly in place with a clip for the laces at the front and the great adjustability of the underfoot strap.

If you get the right fit, nothing is getting past these gaiters.

Durability

These gaiters held up in our side-by-side testing like a champ. After a big trip in the mountains, everything you take with you will look more than a little worn (including yourself). We used these gaiters while guiding on Denali, and after walking down the Kahiltna glacier with our Crocodiles intact, they still looked brand new after a quick wash. These things are as close to indestructible as can be. The 1000D foot panel will resist even the most errant crampon spikes, and the foot buckles are triple bar-tacked and made with a solid piece of metal. It'd be hard to find a mountaineer in the country who hasn't owned a pair of these (and probably still do), and the one universally agreed-upon statement about them is that they last.

Ease of Attachment

The folks at OR have this pretty dialed and made it easy to use this product in almost any conditions. Once you have the instep strap adjusted, they Velcro in place and have a cam buckle top closure. While you can adjust the cam buckle with gloves on, you'll need to take your gloves off to adjust the instep strap, which is another area where this pair loses just a little bit of ground. Also, the bootlace hook is on the top of the gaiter, which means you need to close them first and then finagle the hook down.

These gaiters are relatively easy to attach once you have the fit dialed in, but you'll need to take you gloves off to adjust the instep strap.

Water Resistance

Just like its namesake, the Outdoor Research Crocodile thrives in the wet. They are about as close to waterproof as a gaiter can get, keeping in mind that if you are wading through an ankle-high stream, water can still creep up the inside of the gaiter and wet your feet that way. With a three-layer Gore-Tex upper and 1000 denier foot panel, this gaiter is virtually impenetrable from the outside. It continuously shed water in our dousing test, and no part of the gaiter wetted through even after a prolonged soaking. Keep in mind, though, that the real trick with this gaiter is keeping your feet dry from the inside on warmer days when you still need to wear them. Poor breathability makes this model a less than ideal choice for warmer weather mountaineering. Even the coldest climbs can become sweltering in the heat of the day or on the descent. While there will never be a perfect solution, being able to adapt is still the easiest way to keep yourself comfortable and healthy.

Both the 1000D foot panel (bottom) and Gore-Tex upper (top) shed water effectively and will keep your feet dry all day long, on the outside at least.

Weight

These gaiters are solid and weigh 5 ounces each. They are not the lightest gaiters in this review, but considering the coverage they provide, they aren't the worst either. In addition, in terms of their durability relative to their weight, they are A+ when it comes to keeping you protected.

Value

You'll only have to buy these gaiters once or twice in your climbing career, and that's assuming your climbing career lasts long enough to get through the first pair. That's a pretty good deal.

Conclusion

These gaiters have a specialized niche — you won't want to wear them on a warm day hike, but they are hard to beat in their cold, icy element, and will last as long as you in the backcountry.
