    As someone who hates itchy winter clothes, this is a game-changer. The Smartwool fabric is gentle on skin and handles temperature changes so well. Used it during a snowy weekend in Vermont and never felt too hot or cold. Solved my problem of staying warm without discomfort.

    Dan*******ter

    Love how soft it is compared to other thermal layers. Doesn’t itch at all, which was a big issue for me before ([pain point 1]). Only reason I’m not giving 5 stars is because it took longer than expected to dry after washing. Still, totally worth it for daily winter use.

    Ju*****Lee

    Solid base layer for cold mornings on the ski hill. Fits true to size and feels great under my jacket. Only wish the zipper was a bit smoother, but hey, can't win 'em all. Keeps me warm and dry—nailed my [痛点2]: moisture control without that clammy synthetic feel.

    Lin******re

    Love how cozy it feels but light enough to move freely. Was worried about sizing but it fits true. Only wish the zipper was a bit smoother.

    Emi******ter

    I usually struggle with staying warm during winter hikes without feeling like a sweating mess, but this Smartwool base layer totally gets it right. The 1/4 zip lets me vent heat when I'm climbing, and the merino keeps me cozy even when it's freezing. No itch, no stink—just perfect warmth. Solved my [痛点1]: staying regulated without bulk.

    Emi******ter

    I bought this base layer for skiing in Colorado, and it’s perfect. The merino wool keeps me warm even when it’s freezing outside, and I don’t get that clammy feeling when I sweat. It solved my problem of staying warm without overheating — exactly what I needed for winter sports.

    Sam*******rey

    I’ve struggled for years with base layers causing rashes or holding sweat—this one completely fixed that. Soft merino fabric eliminates chafing and odor, directly solving [痛点3]. Worth every penny for sensitive skin and active winters.

    Lin******eed

    Great fit and warmth, though I wish the sleeves were just a bit longer. Still, it handles moisture way better than any other base layer I've tried. Definitely helps with [痛点2]—managing sweat during active days outside.

    Chl*******ett

    Nice material and fits well, but I expected it to dry faster after washing. Works okay for light activities, helps a bit with [痛点2], but not ideal for high-intensity use where quick drying matters.

    Ja*****ee

    Great fit and warmth! Wore it hiking in Banff and stayed comfortable all day. Moisture-wicking really works—didn’t feel clammy even after climbing.

Customer Reviews

  • I’ve had the Zamberlan 309’s for a month now and have put about 75 km on them. They fit great right out of the box but have been getting even more comfortable every time I hike. I like the lacing system and the ability to adjust the tightness in different parts of the boot. Although they’re fairly new they are definitely waterproof and have good grip. Hopefully they hold up over time.

  • One of the best all around boots you can buy. Good for 2 hour hikes or 4 day backpacking trips. Not too stiff, but lots of support.

  • I bought these last month at the tail end of winter. I am 5 ft 7 woman approx 160 lbs. They are a great size and weight for me. I wanted a pair that would be easy to strap on as I have arthritis in my knee. The harness is easily adjustable. The back strap is a little fiddly to connect the hole into the spike and to insert the extra strap into the holder. However that is minor and after a few tries I got the hang of it. Only reason for the 4 instead of stars. Great product and I look forward to many years of use.

  • Sturdy, waterproof, hiking sneaker. Feels like you are floating as you walk.

  • My wife and I traveled for two months last winter. These were the only shoes/sandals I brought, and they served me well through some of the harshest conditions including the desert outback in Australia, the rain in New Zealand, and several encounters with saltwater... They are the perfect everything sandal/shoe for hot, warm, and moderate climates. When we were traveling, we did lots of walking, hiking, beaching, etc. These sandals were up to the challenge of a good hike, or just recreational walking around town. While they are comfortable and breathe well, They don't easily dry while being worn, and because of the toe cap/footbed design, have a tendency to sometimes trap pebbles or sand, requiring that your remove them to shake it out. Also, after time, they really started to stink and required a through cleaning/bleaching which is strange for me because none of my other shoes ever stink. Overall, an excellent comfortable everything sandal/shoe with a few very minor flaws.

  • I bought this during the MEC sale. I wear a size 6 women boots and the size small fits my boots. I can't compare to size XS which is what is recommended for my boot size as they didn't have it in the store but my size small works and fits me well so no complaints here. Haven't used it for that long so I can't talk about the longevity but I did use them for winter hiking and they are 100% waterproof and the velcro still works!

  • l love these gaiters. They kept my feet dry in 3 days of continuous rain. I find them easy to adjust and don't budge or slide down as I am a small human. I recommend them to all my friends who want quality gaiters for a modest dollar amount. Would love to see more colours in the future!

  • Had these a short time but so far they seem pretty nice. Good quality and comfortable. My previous Targhee III’s were splitting at several seems, but these are reputed to be less prone to this.

  • I bought my first pair back in 2006 and last year replaced them with new version. Materials are high quality and very durable. We wear them 3 seasons fall/winter/spring when they are needed. Definitely happy with them. Follow sizing chart which works well for me.

  • I recently bought a pair of these from MEC and have not yet tested them in the field, but I love their hand-made Italian construction and strength, their good Vibram soles, and their general feel and good quality. They fit well, feel supportive enough for most hiking, and are a very good price. Unusually, the tongues in these boots have no seams, but are directly part of the outer boot leather, which is a bonus to not have leaking tongue seams as in most boots, and it's a sign of high-quality design and manufacturing. Zamberlan have been making boots since 1929, almost 100 years. I love these boots.

  • Loved the Targhee III's, they did start to crack after countless miles and several years of abuse, the IV's have addressed this while keeping the same comfort. I was able to take them out of the box and hike a rough 10 mile hoke with np break in.
