>>151018>need a tent, sleeping bag and sleeping padNot that much information but I'll try. I assume you're from Denmark then and don't need too extreme gear, but since you're solo and a philosophy student it' should be reasonably light gear, for 1 guy and 3 seasons those three items should combined weight not more than 3kg if possible.
>tentI recommend a tarptent contrail, thats a really light small tent single wall tent, but it does a fair job at keeping wind, rain and bugs away from you and comes at around $200. If you find another ultra light tent in the price and wight range you should also be fine.
>sleeping bagthis depends on you, your size, how you sleep and how fast you feel cold. generally go for a light down sleeping bag, they are lighter and compress smaller than synthetic ones. Since you only go 3 seasons, a noname brand from your local outfitter will do, temp rating should go down to around 5-8°C, should go for around $100. Better sleeping bags will cost significantly more, but you don't need them in your scenario.
>sleeping matSplurge here, a good nights sleep is essential. theres closed foam mats, self inflating mats, and inflatable mats, major brands are Thermarest and Exped, I personally prefer inflatables from Exped, but go to the shop, test all mats available, buy the one you feel most comfortable on.
