Bike trip in Iceland

Hello ☺️

To be original, I'm here to ask for advice on gear ☺️
I'm going on a bike trip in Iceland, and it's the perfect opportunity to invest in quality equipment ☺️

1 The sleeping bag

This -15°C sleeping bag at this price is very tempting 🫣. But is it good quality? If not, what do you recommend?

2 The tent

I'm hesitating between:
– MSR REMOTE 2
– HELSPORT RINGSTIND PRO 2
– SLINGFIN PORTAL 2

What do you think? Should I wait for Black Friday to get a better price?

3 Clothing

I'm looking for good thermal clothing, made from eco-friendly materials and that won't cost me a fortune (am I asking for too much? 😂).
What do you recommend?

4 Bags

Same question for bike bags that are resistant to heavy rain. I imagine waiting for Black Friday is recommended.

5 Other

If you have any tips on stoves or other gear, I'm all ears!

Looking forward to reading your replies, thank you 🙏
