Indoor or outdoor Borussia Dortmund flag
Updated: October 2026
You are choosing between a bedroom wall and a garden pole, and the listing line does not always match how buyers use the flag. An indoor or outdoor Borussia Dortmund flag, in this amazon.co.uk set, is not one cloth with two settings. The small official flag is listed for indoor use while reviewers describe gardens, and the long flag listed as outdoor is the one with seam and hanger tears. The [Borussia Dortmund flag comparison](/hub/flags/borussia-dortmund-flag) is the table. There was no lab weather test. A qualifying purchase can earn a commission at no extra cost to you.

What the listings actually say
Three use lines sit on these pages, and they do not agree. The official polyester flag, 150 cm by 100 cm at £10.97, says indoor. The official viscose flag, 150 cm by 400 cm at £63.21, says outdoor and weather resistant. The Desert Cactus prints, £35.80 to £37.86, say indoor or outdoor. Flag E also says indoor in a specific-use field. This page will not collapse those two lines into one.
Fibre is not a weather certificate. Polyester and a machine wash, viscose with a cold wash and no tumble dry, or 150D polyester and hand wash only, are care lines. 150D is denier, not grams per square metre. The £10.97 page says double-sided and does not say whether that is a second cloth or a bagged layer, which is heavier when wet.
The small official flag in a garden
The £10.97 flag is the indoor listing that reviewers fly outside. It is 4.6 from 162 reviews, about 100 g, a pole mount. Buyers put it on flagpoles and in gardens, including one note about a house facade in wind and weather. That use does not rewrite the indoor line.
About 100 g across 1.5 square metres is a light flag. It flies in a modest breeze and snaps when the wind rises, so a garden comment is not a season-long rating. No pole is in the box. Choose it for a bedroom, a window, or a pole you will take down. If you need the page itself to say outdoor, this is the wrong row. Hanging either header is on the how to hang page.
The long viscose flag in the weather
The 150 cm by 400 cm viscose flag is the outdoor listing, at £63.21, 4.6 from 234 reviews, with a hook and a cold wash. The page says garden, outdoor and weather resistant. Colour is praised, and one reviewer reported a storm survived.
An edge tore within about two months without a storm. The hanger ripped in a first small wind. Seams opened after about four weeks, or by the end of a season. The weight cell says 100 g, the same number as the small flag. Buy it for a portrait you will take down. Weather resistant is not a guarantee.
The 3 ft by 5 ft prints say indoor or outdoor and have at most three reviews. That is not a weather trial, and a mirrored reverse is not a tougher stand-in.
When to take it down
Lower a normal flag when the wind passes the maker’s guide. One note uses Beaufort 6, about 31 mph. Another uses about 25 mph. Neither is a test of these flags. If a gale is forecast, or the cloth is cracking like a whip, bring it in.
Leaving a flag up because a listing said weather resistant is how a light flag tears. Do not tumble-dry the viscose flag or machine-wash a hand-wash print. A flag that stays on a pole is also a planning question, on the planning rules page. Who should skip the long flag on price is the best Borussia Dortmund flag page.
Common questions
Can you fly the £10.97 flag outside?
The listing says indoor. Reviewers still fly it in gardens, including one note about a house facade. You can try it outside if you will take it down. Those reviews do not make the polyester waterproof, and no pole is in the box.
Is the £63.21 flag the outdoor one?
Yes. That listing says outdoor, garden and weather resistant. It is viscose, 150 cm by 400 cm, with a hook. Reviews also describe seams and the hanger tearing within weeks or by the end of a season. Buy it only if you will lower it.
Why do reviews say it tears?
The comments name a part and a time: an edge within about two months without a storm, the hanger in a first small wind, seams after about four weeks of match-day flying, or a season if it was lowered. That does not mean every flag fails.
Are the Desert Cactus flags outdoor?
The shared bullets say indoor or outdoor. The cloth is 150D polyester, hand wash only, with two grommets and no pole. 150D is not a gsm weight, and the reviews do not record a winter on a pole. A room or a fair-weather pole is the honest use.
What is different about flag E?
Flag E is £37.86 and 5.0 from three reviews. The bullets say indoor or outdoor, and a specific-use line says indoor. Do not merge those lines into one outdoor rating, and do not rank the letter on stars. The indoor line is the extra caution.
When should you take any flag down?
When the wind passes the maker’s guide, and earlier if it is already slamming. One firm uses Beaufort 6, about 31 mph. Another uses about 25 mph. Both are guidance, not a test of these flags. A gale forecast is reason enough to bring any of them in.
