Frustrating Experience with Refund Process

I have returned several items to the company, and I have not received a refund of £1500 for over 8 weeks, which is nearly 2 months! I reached out to the support team every couple of days but received only vague replies stating they would escalate my case to the appropriate department. £1500 is a significant amount! I recommend avoiding purchases from this service, even though the quality is decent.

No refund received!

I returned several items to the company, and I haven't been refunded £1500 for over 8 weeks—almost 2 months! I've reached out to customer service every couple of days, but their responses have been very passive, stating they will forward my case to the relevant department. £1500 is a significant amount! I recommend avoiding any purchases from this company, despite the quality not being bad.

Issues with customer support

I attempted to return an item, but they sent it back to me. After re-sending it, I haven't received any updates for 5 weeks. It's now over two months since I first tried to return the item, and I'm still waiting for my refund.

Good value for the price

It’s pricey, but you can be assured that the quality is top-notch for outdoor equipment.

Disappointing shoes – Mammut Ducan II Low GTX

I regret purchasing these shoes. After just one forest walk, the front of the right shoe was punctured, rendering the waterproof lining ineffective. I had to use duct tape to continue. The situation worsened: after 700 km of walking, the soles were heavily worn; after the first walk, the puncture made the waterproofing useless; by 1500 km, the shoes were unsafe and slippery; soon after, the other shoe's sole wore through as well. To make things worse, the company's customer support was slow and unhelpful, taking 3 months to recover only 60% of the purchase price. This was the most expensive pair of shoes I've bought, but also the worst, lasting barely 7 months. For comparison, my previous shoes lasted 6 years and over 5000 km for half the price. The company's quality has declined significantly—worse than cheaper brands, despite charging more. I doubt I will trust them again.

Lack of customer service and slow delivery

I love the gear, but it’s been 13 days since I ordered, and there’s still no sign of my package. It’s not even in the same country as me, and no one is responding to my inquiries.

Beware of black spots on jacket

I purchased a £425 insulated jacket in red, which is warm and initially pleasing. However, I noticed that the fill contains dark feathers that show through as spots, resembling oil stains. The company's customer service responded that it's a natural product and suggested pulling the dark downs into the background. Seriously? Apparently, the information about dark spots is in the care section, which we all read before purchasing, justifying their stance. I once regarded this company as a quality brand, but it’s clear they don’t stand by their products, using the excuse of 'responsibly sourced' materials. Now I have a jacket with unsightly spots that will never be worn.

Poor service for a supposedly high-end brand

I was shocked at the service. I expected more from this brand, especially after paying a premium. Their service is worse than many cheaper brands I've encountered. They were reluctant to replace a battery clip on my avalanche beacon, which was a manufacturing issue. This minor fix could potentially save lives. I have a large community of outdoor enthusiasts and will now advise them to choose other brands that offer better support.

Disappointing mountaineering shoes

I bought mountaineering shoes that are designed for rocky terrain. They looked great and felt comfortable, but after 15 months of light use, one sole started to disintegrate, and both boots developed holes that left my feet wet. Customer service claimed there was no warranty because they were 'worn.' I’ll be returning to a different brand that offers better quality and value.

Shoes of terrible quality

The quality of these shoes is unacceptable. I've been waiting for a refund for two weeks for subpar shoes, and customer service has been completely unresponsive. The shoes even arrived with burnt stains. This brand is not worth the money.
