Here's what others have to say...

Any idea when the black will be restocked in XL?

Hi Todd,

Looks like we are set up to get some XL's in both the black and red sometime around the beginning of November.

Do you think this gaiter with the 3 layers of gortex would prevent a snake bite from penetrating?

Best Answer

Hey Kevin,

I would say it would slow them down a bit, however it would not prevent the rattlesnake from penetrating through. If that's what you're looking for you should check out a leather set of gaiters.


Simply Amazing

  • Familiarity:I've used it several times

These gators do an extremely good job of keeping snow and ice out of boots. The last time I wore them I was climbing Boundary Peak in Nevada right after a heavy snow storm. I hiked approximately 6 miles in deep powder with my legs sinking into the snow with every step. These gators keep every bit of snow and moisture out. One of the most effective pieces of gear I've ever gotten.

Hey Robert - Leta here with OR. Thanks for the great review. There is a reason that the Croc Gaiter is considered one of OR's pinnacle pieces, and why it is the industry standard to which all other gaiters are compared!



Single, best piece of Gear

  • Familiarity:I've used it several times

This is by far my most favorite piece of gear as the value is unmatched. The 3 layer Gortex and the Cordura made these things bullet/waterproof. Or at least I think it would hold up to waterbullets- ? : /.

Anyway, these things are exactly what you are looking for. They fit great, don't sag, they have the toughest strap I have seen to competitors, and they fit all my Salomons beautifully. (I have various XA 3D pros and the 3D comet boots. (Again... you just cant beat Gortex). The gaiters have a hook at the base to attach to the lowest part on your laces to prevent riding up and reduce snags.

My experience- Multiple hikes through mud, snow, slush, and deep puddles. My last trip found me in a situation that if I didn't bring them, I would have been in quite a bit of trouble. I leaped across this ICE COLD creek from solid sand to what I thought was going to be solid sand on the other side. Turns out it was deep soft mud. I quickly found myself high stepping trying to get out before I sank beyond the rim of the gaiters. This stuff was serious perma-frost type mud. I got out after looking very strange and panicked. I thought I was going to be soaked... thought there is no way that water didn't infiltrate my gaiters and boots.

GORTEX O.R. Gaiters combined with GORTEX Salomon boots = Dry comfortable lower extremities.

If you are looking for the serious gaiters.. Stop here. They cannot get any better.

Work awesome

  • Familiarity:I've used it once or twice and have initial impressions

Used these to hike back to our deer camp in the snow. Did a fantastic job at keeping my feet dry! Super happy with this purchase.


Second pair.

  • Familiarity:I've put it through the wringer

Absolutely love these gaiters. On my second pair. First pair lasted 15 years.


Instantly became a vital piece of gear.

  • Familiarity:I've used it once or twice and have initial impressions

First to note: the sizing listed on the chart for these things is actually for mountaineering boots, so size down if you plan on using them on hiking boots. Which is what I did after a quick, easy exchange.

Down here in Florida we definitely don't have to worry about ice and snow, but I got these wanting to protect my new boots from water and rocks, as well as keeping ticks out.

Even on our cooler nights, it's still warmer than the rest of the country I'm sure, yet these are breathable enough that they were not at all uncomfortable. First day hiking it was 40-50s and worked great keeping out our "highland" sugar sand, cactus, and bugs. On the second day the temps were in the high 70s, and the terrain was rocky, thorny, and even muddy in places. These gaiters performed flawlessly in all environments, never once did I feel the need to take them off for a breather.

We even did some light spelunking, and my boots were still clean and dry.

Overall very recommended, I don't understand how I went my whole life without using gaiters!


The word of the day is bombproof!!!

  • Familiarity:I've put it through the wringer

Okay, Wow I have shopped and shopped and shopped for the best gators from Mountain Hardwear (totally my favorite outfitter by the way) and Black Diamond. I read all the reviews and watch a few videos on certain models..... I had found 2 Hardwear ones and 1 Diamond one! I didn't even look at Outdoor research! I didn't really look at prices either! So let me tell you what I was looking for and maybe that will help. I live in a place where if you decide to go off trail you better be wearing bombproof cloths. So I needed something to keep me from tearing the legs out of my pants. Pants costing 100 dollars or more a just not work tearing them that being said I also like to trail and do some ice climbing and trying to find one pair of gator that would do all that seem like an impossible take....well look no further! You have found everything you are looking for!!!!


Staying clean and dry

  • Familiarity:I've put it through the wringer

Wow, I am so thankful I went with these gaiters for my AT thru hike. These gaiters paired with my AKU boots have allowed me the privilege to say I am the ONLY thru hiker this far to NOT have wet feet. They have stood up to the abuse I the rocky terrain of ME (Maine). Also, I have been able to ford shin-deep crossings without having to remove my boots. The kicker for me though was when I sunk mid-thigh deep in a bog atop Mt Success. I panicked as this would be the first time on the trail I would have wet feet -nope! Because the way these gaiters cinch down at the shin, the mud did not trickle down my leg behind the gaiters - awesome! Thy are so great, another fellow I have been hiking with went ahead and picked up a pair in Gorham, NH. great product and very tough and reliable. Way to go on this product.

Solid Gear for Mountain Ops

  • Familiarity:I've put it through the wringer

Breathable gore-tex material won't sweat out your legs. Keeps the snow out. They've saved a few pairs of pants from tears without so much as a fray. keeps my pants cinched up tight to keep them from getting caught on my front points. cinches down over your boots to keep the snow out. Heel strap is very durable. I wish the calf cinch strap had a better way to secure the tail. I tuck it in the top but it always comes out. I haven't used these in a temperate climate but they are great for alpine mountain ops. I wouldn't want shorter ones. Got the Large and work great on my size 11.5 Scarpa and Vasque Mountaineering boots.

Don't Leave Home Without Them

  • Familiarity:I've put it through the wringer

These crocs are tough and been a staple to my outdoor gear for years. There are no other gaiters that withstand the rugged beatings, keeping the wet and gunk out and always staying secure.

Only problems I've ever encountered were self inflected tears via crampons and nothing that the old repair kit duct tape can't handle.


The One and Only

  • Familiarity:I've used it several times

This is the only gaiter I will ever use when working in the snow or on hikes where I may come across large water crossings. Although I have only used these a handful of times, I have used them in a different environment during each use. These gaiters are durable and fully waterproof, and if you're disappointed OR will back you up for the lifetime of the product.

I know this sounds like a mistake, but my...

I know this sounds like a mistake, but my calf is 21 inches around at the widest part. So, despite being a size 11 EE in shoes, would I be an XXL in the gaiters?

Best Answer

You should be fine in the Xl size gaiter. It will fit your boots best and should have room for your calfs. If you are unsure you can always chat into a backcountry rep and they can help answer any questions or even set up an order with both sizes for you to try with a free return label noted on the order.

You have to try these on. I have the same issue where they claim this size or that should fit but xxl is too narrow through the calves. you'd think they'd make these bigger considering most of us are wearing layers on our legs whenever we need a gaiter like this. good luck

The EXPEDITION crocodile gaiters have a larger circumference upper calf area to compensate for bulky layers and larger calves.

yeah, i read that too. but the xl expedition crocs are roughly the same size as the xxl regular crocs. don't make an xxl in the expedition crocs. useless. I can't get them on my calves and i'm by no means the biggest person that would be interested in buying these if they weren't made for stick people.

I have a 22 inch calf and had to return these as I couldn't get them on even just over a pair of jeans. I have yet to find gaiters anywhere that really do work for us Popeye-legged guys, but that's what I'm used to since hiking pants, muck boots, and even jeans are tough to find too when you've got a calf as big as your kid's waist.


Good for PNW

    Just picked these up. Great for general mountaineering use in the Cascades. Tough and waterproof. Keeps the snow out. I wear a 9.5 in mountaineering boots, and went with a medium in these gaiters. The large would have left too much slack in the calves.
