    Soft merino blend makes all the difference — no itching, no overheating. Wore it all day from hike to coffee run and still felt fresh. Tackles [痛点1]: odor retention in workout gear. Smells clean even after long use.

    Rya******rds

    Bought this as a gift, and my girlfriend was thrilled. She has always had issues with synthetic fabrics causing irritation—this bra fixed [痛点2] completely. Natural fibers feel gentle on skin, and she wore it through spin class without any discomfort. Impressive durability and eco-friendly too. Will definitely buy again.

    Jes******ee

    So soft and breathable—I forget I’m even wearing it! Ideal for hot Canadian summers when other bras would leave me soaked. This one handles moisture perfectly and doesn’t irritate my sensitive skin. Definitely solves [痛点2]: keeping fresh and irritation-free during long wear.

    Meg******res

    I love how natural it feels during movement. The seamless design means no irritation under my tank top. Perfect for both gym sessions and casual wear. Solves [痛点2]: visible bra lines under tight clothing.

    Chl*******ett

    Great fit and really comfortable for low to medium intensity yoga and walks. Addresses [痛点3] well—staying put without squeezing too tight. Only wish it came in more colors. Fabric feels premium and breathes well, which is key in humid weather.

    Emi******ter

    This bra is a game-changer for my daily workouts! I used to struggle with discomfort during high-impact sessions, but the icebreaker Siren Bra provides just the right support without feeling tight. The fabric stays cool and wicks sweat like a dream—no more chafing or overheating. Perfect for yoga, running, or just lounging. Finally found one that solves [痛点1]: staying comfortable and supported all day long.

    Lin******im

    As someone with broader shoulders, finding a bra that doesn’t dig into my arms was tough. This one offers excellent range of motion and support without pinching. Truly solves [痛点3]: restricted movement from poorly designed straps.

    Mia******son

    Comfortable and soft, definitely helps with moisture management ([痛点1]). However, I expected slightly more support for running. Works well for pilates or casual wear. Good quality, but may not suit high-intensity needs for larger cup sizes.

    Rac******nn

    Comfortable and stylish, but sizing ran slightly small. Had to exchange for a larger size. Support is good for low-impact activities, but might not suit high-intensity needs. Still helps with [痛点2]: discomfort during daily layering under clothes.

    Meg******res

    Great fit and amazing comfort. It’s not fully lined, so I pair it with a tank top for coverage, but that’s a small trade-off. The natural merino blend feels great against the skin and eliminates odor even after multiple uses. A solid solution for [痛点3]: staying odor-free and comfortable between washes during travel or busy weeks.

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!

  • I am in my 3rd year of wearing Keen boots and will not buy another brand period. They have always had a great fit and no break period. I wear them everyday at work and for pleasure.

  • 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.
