warmth isnt necessarily applicable in terms of a company's spring/summer line, as that is not the intended functionality of said hoodies/jackets. would you wear a windbreaker in the middle of winter and then rant and rave about how it costs more than a down filled jacket, whose intended purpose is warmth.
price is entirely relative, you can make the same argument with any outerwear company.

as you mature and smarten up you wouldnt wear summer clothing in winter and expect it to keep you warm.
and to PASKALEV
you may think something is "buttugly" however they seem to be selling well. you said you liked the shacket, good, buy it if you want, dont buy the other stuff. the reason they design and release a range of patterns and designs in each category is an attempt to appeal to everyone in their target market.
i like nike sb, but that does not mean i like EVERY shoe in EVERY colorway. this can be said with any clothing/apparel/fashion company. fashion follows trends, jiberish generally attempts to stay ahead of or at least keep up with these trends.
look at some fashion trends that have developed over the years, kids used to HATE tight snowpants, now look at how many companies make a slim fit line, or have multiple slim offerings. same goes with jeans, etc. same can be seen in music and movies, and almost any other market in the world.
that isnt to say that you personally will learn to appreciate jiberish's summer/spring designs this year, but id be willing to bet that many people who are hating on it now, may be wearing something rather similar to this line now. again, not saying this is true for everyone, but it does tend to happen to a large majority.
