I noticed that Massdrop has posted a copy of what is described as the Fitsock LIfetime Warranty on the product description page for the Mountain Crew Socks drop.
Following is the language which comprises the Fitsok LIfetime Warranty:
This guarantee covers all Massdrop x Fitsok socks, including the Merino Hiker, Merino Low-Cut, Merino Crew, and Mountain Crew models.
For warranty inquiries, please email firstname.lastname@example.org or call 877-454-7765.
Please note if the socks you return are not in stock, Fitsok will replace them with the most similar style or color available.
My interpretation and understanding of this warranty is that if the Mountain Crew Socks don't fit properly, shrink, wear out, fray, tear, rip, or are defective, etc., then I can return them to Fitsok for a replacement pair.
There is very little detail, and no mention of who pays for shipping, and there are no disclaimers, or conditions listed, so it seems to be unconditional, like the warranties offered by Darn Tough, Farm to Feet, Icebreaker, Wrightsock, et al.
The language however is definitely not as unambiguous, ironclad, or unconditional as the language found in the Darn Tough, Farm to Feet, Icebreaker, or Wrightsock warranties, which are my preferred socks due to their high quality, reputation, and the warranties.
Some companies like Wigwam have a lifetime warranty, but not unconditional, and it only covers defects in materials, or workmanship, and not normal wear and tear; so basically no warranty, as compared to the other companies I mentioned, which will replace if your socks for any reason like normal wear and tear, or of they just plain wear out, shrink, don't fit, etc.
Wigwam does however make very good socks, unlike Thorlos which last time I checked had only a thirty (30) day warranty, and Thorlo socks have always worn out very quickly in my experience, so needless to say that I will never purchase a Thorlo sock again.!
Anyway, I digress...
So, it has crossed my mind that if I purchase the Fitsok, and they wear out, that Fitsok will deny my claim by stating that there were no defects in materials, or workmanship, and that they don't cover normal wear and tearlike Wigwam.
By the way... I have searched the Fitsok website, and could find nothing there about their warrenty.
Fitsok only has a page that describes their limited time return policy.
Fitsok also does not list the fibre breakdown in all of their socks listed on their website.
Fitsok uses terms like ISW Wool, and Shadow Yarn to describe the fibres used on their socks, but they do not explain what those terms really mean, and again, there is no fibre composition breakdown.
I noticed in this drop that the fibre composition seems to be incorrect, as Massdrop has listed the main fibre as 73% Merino Wool, and Coolmax Polyester, but they do not state or more finitely breakdown the percentage of each fibre separately.
Another Massdrop purchaser has stated as much, when he received the socks, and read the actual Fitsok label.
I have asked him to reply with the fibre percentages listed on the label of the socks that he received.
On paper the socks seem to be a good deal for the price, as the fibre composition seems to be a good combination, especially when combined with the lifetime warranty.
