Bamboo Cool Bamboo Underwear
Soft bamboo viscose underwear and loungewear sold in multipacks, with a 30-day First Pair Guarantee, free shipping over $49 and strong ratings on the brand's own product pages.
Comfort-focused multipacks at fair prices, with a few claims to read carefully
Bamboo Cool sells bamboo viscose underwear, pajamas, socks and tees for men, women and children. Its multipacks start around $35, it ships free over $49, and its 7-pack men's underwear shows 4.81 of 5 from 550 reviews on its own site.
For anyone who wants soft, breathable everyday underwear in value multipacks, Bamboo Cool is an easy brand to try, and the First Pair Guarantee lowers the risk for first-time buyers. The caveats are about marketing language and proof: bamboo viscose is a manufactured rayon fabric, the ratings we found are mostly on the brand's own pages, and parts of its return wording are inconsistent.
Right for
- Shoppers who want soft, stretchy everyday underwear in 3 to 7 packs
- First-time buyers who like a guarantee that usually needs no return shipping
- Households shopping for men, women and kids from one brand
Wrong for
- Buyers who want a plain cotton-only or organic-cotton garment
- Shoppers outside the United States, since the brand ships only within the US
- Anyone who wants independent lab proof of antibacterial or hypoallergenic claims
+What it gets right
- Value multipacks. Women's multipacks start near $35, a 7-pack of men's underwear sits around $57 to $67, and singles start at $20.99.
- A wide range. 173 listings covering boxer briefs, trunks, briefs, boyshorts, bikinis, pajamas, socks and tees for men, women and boys.
- First Pair Guarantee. First-time customers can claim within 30 days of delivery, and approved claims generally do not require sending the item back.
- Strong on-site ratings. The 7-pack men's underwear listing shows 4.81 of 5 from 550 reviews.
- Free shipping over $49. Orders ship within one business day and usually arrive in 3 to 7 business days in the US.
- Cancel before it ships. Orders can be cancelled any time before dispatch, with refunds in 5 to 7 business days.
- Certifications claimed. The brand says its fabric carries FSC, OEKO-TEX 100, OCS and BSCI credentials.
−Where it slips
- It is viscose, not bamboo cloth. Bamboo viscose is rayon made from bamboo pulp, and the FTC says such fabric should be described as rayon or viscose, not simply bamboo.
- Antibacterial wording. The brand says its fabric naturally resists bacteria, but the FTC says rayon made from bamboo does not keep the plant's natural antimicrobial properties.
- Mostly self-hosted reviews. We found no Trustpilot profile and little independent coverage, so ratings come mainly from the brand's own pages.
- Inconsistent return wording. The FAQ describes a 30-day return of unworn items with customer-paid shipping, while the newer policy page describes a guarantee with no return needed. Defect reports are 7 days in the FAQ and 30 days in the policy.
- Limits on the guarantee. It covers first-time customers only, one claim per customer, excludes Final Sale, Clearance and bulk orders, and the remedy is chosen by support.
- Reference prices. About 150 of 173 listings show a higher regular price, so compare the sale price rather than the crossed-out one.
- US shipping only. The brand says it is headquartered in Australia but ships only within the United States for now.
Weighted for comfort value, honest claims and what happens if the fit is wrong
Value, fabric honesty and return terms carry the most weight, ahead of range and reputation. This is a desk-research score: we have not worn or lab-tested the garments.
The long version
What the brand's own pages say, what the fabric labels mean and where to read the fine print.
What Bamboo Cool sells
Bamboo Cool is a bamboo viscose apparel brand. Its public product feed lists 173 items: men's boxer briefs (the largest group), boxer shorts, briefs, trunks, undershirts and pajamas, women's briefs, boyshorts, bikinis and thongs, boys' boxer briefs, socks and tees. Most are sold in multipacks of three to seven. The brand says it sells mainly through its own store and Amazon, and it is also listed at Walmart.
Value for money
Women's multipacks start near $35 for a five-pack, men's seven-packs run from about $57 to $67, and a tank nightgown starts at $20.99. The home page promotes 20% off a first purchase and free shipping over $49. About 150 of the 173 listings show a regular price above the sale price, so compare the sale price per pair rather than the crossed-out number.
What customers say
The Ultra Soft Men's Underwear 7 Pack shows 4.81 of 5 from 550 reviews on the brand's site, and several other listings carry hundreds of reviews. Those ratings are hosted by the brand, so we treat them as a good sign but not independent proof. We found no Trustpilot profile for the store and little independent coverage.
Fabric: what bamboo viscose means
The brand says its fabric is bamboo viscose with FSC, OEKO-TEX 100, OCS and BSCI credentials. Viscose is a manufactured rayon fibre, made by dissolving bamboo pulp, and the FTC says products made this way should be labelled rayon or viscose rather than bamboo. The FTC also says rayon made from bamboo does not keep the plant's natural antimicrobial properties, so the brand's antibacterial claim should be read as marketing. Ask the brand for certificate numbers if certifications matter to you.
Returns, cancellation and shipping
The First Pair Guarantee lets first-time customers contact support within 30 days of delivery; support may offer a replacement, gift card or refund, and approved claims generally need no return. It is limited to one claim per customer and excludes Final Sale, Clearance and bulk orders. Orders can be cancelled before they ship, with refunds in 5 to 7 business days. Shipping is US-only, free over $49, processed in one business day and delivered in 3 to 7 business days.
Where to read the fine print
The FAQ and the policy page do not fully match. The FAQ describes a 30-day return of unworn, unwashed items with customer-paid return shipping and a 7-day window for defects, while the newer policy page describes a guarantee with no return needed and a 30-day window. Ask support to confirm in writing which applies to your order. The brand says it is headquartered in Australia but ships only within the United States.

How this review was put together
This is a desk-research review. We did not wear or test the garments. Policies come from the brand's Returns, Refunds, Cancellations and First Pair Guarantee page, Shipping Policy, FAQ, Terms and affiliate page; catalogue and price figures from its public product feed and home page on 1 Oct 2026; and the on-site rating from one product page. We found no Trustpilot profile and little independent coverage. Fabric guidance comes from the U.S. Federal Trade Commission. The brand's terms do not allow commercial reuse of its site content, so we wrote our own text and made our own graphic. We could not read the affiliate programme's terms in full.
Big Time Bikers is independent and is not affiliated with Bamboo Cool. The link to its store is an affiliate link: if you buy through it we may earn a commission at no extra cost to you, and this never changes a score. We did not receive payment or free product for this review.
