I have been backpacking for 6 years, mostly three-season weekend trips in the Adirondacks, and other parks in the Northeastern US. Additionally, I try to take at least one 5-7 day trip each summer to other destinations in Canada, Western United States and Central America. I use lightweight gear on a budget. My multi-day pack weight is around 20-25 lb (9-11 kg). I enjoy sleeping comfortably and cooking a hot meal at night.

The Guideline Eyegear Draft Sunglasses (hereafter "sunglasses") arrived in minimal packaging. The glasses themselves are quite light weight. They feature a wraparound light weight frame with a heavy rim on top of the lens, and no rim on the bottom.
The manufacturer's website lists the frame material as Grilamid BTR. With a bit of online sleuthing I found out that Grilamid BTR is a biopolymer manufactured in Switzerland by a company called EMS-Grivory. It is notable that the company focuses on the environmental impact of its manufacturing activities. Grilamid BTR is made from 51% castor oil, a renewable biological resource, and manufactured using CO2-neutral energy such as hydroelectricity. EMS-Grivory states that other properties of Grilamid BTR are directly comparable to conventional crude oil based polymers. Their marketing material mentions "excellent impact strength," "high dimensional stability," and "good UV and chemical resistance"
The polarized lenses are made from 1.4 mm thick Polycarbonate. Both the lenses and the frame are brown. Also present are floating soft nose pads.
In addition to the sunglasses the package included a soft black cloth case with a Velcro closure. There is not much to be said about the case. It is lightweight, and looks like it will protect the sunglasses well enough.
TRYING IT OUT
The glasses feel very light. I will definitely appreciate this on the trail. The lenses are quite large. They covered my entire field of view, which is definitely a plus. The semi-rimless design works well as well. Sports sunglasses are normally made with a heavy rim on all sides for strength and stability. This rim usually blocks out a good portion of the view. Not so with the Guideline Draft sunglasses. The view is completely unobstructed.
On the flip side, the lightweight semi-rimless design makes me wonder how they will fare stuffed into an outside pocket of a backpack. A second point of concern for me is whether the earpieces will be comfortable after wearing them for a few hours. This is a common problem for me with most sunglasses. There is nothing specific about this particular pair of sunglasses which makes me believe they will be particularly prone to this problem.
Finally there is the question of style. I happen to think that these sunglasses are quite stylish, but everyone has their own taste, and there is no right or wrong answer here.
