Icebreaker Merino Sprite Hot Pants (Women's) Review (2026)

What it is

The Icebreaker Merino Sprite Hot Pants are a boyshort-style base layer underwear for women built from merino wool, positioned as a thermal and travel layer rather than everyday cotton underwear. Icebreaker describes the fabric as a corespun jersey construction, where durable nylon fibers are wrapped in merino wool to add strength while keeping the next-to-skin softness merino is known for. The hot pants cut sits between a brief and a short, offering more coverage than a typical brief, which suits wear under skirts, dresses, or as a base layer in cold weather. This makes them a common pick for one-bag travelers who rewash underwear in a sink rather than packing many pairs.

Features and specs

According to Icebreaker's own product information, the fabric blends merino wool with nylon for durability and a touch of elastane for stretch and shape retention, giving the garment a slim, body-hugging fit. The design includes a wide waistband and offset side seams specifically meant to reduce rubbing and keep the garment in place without feeling constricting during a day of walking or sitting on transit. Merino wool is naturally temperature-regulating, helping the fabric feel less clammy in warm weather than many synthetic base layers, and it carries merino's well-known natural odor resistance, letting a single pair go multiple wears between washes on the road.

Build and materials

Icebreaker's care instructions call for machine washing warm or cold on a gentle cycle, then either line drying or tumbling on low heat, which is simpler care than many merino garments that require hand washing. The corespun construction, wrapping nylon around merino fibers, is meant to address one of merino wool's common weaknesses, that pure wool garments can wear thin or develop holes faster under repeated stretching and washing than synthetic blends. This build detail should make the Sprite more durable over a travel season than a 100 percent merino product, though it will still show wear over years of heavy use.

Value

Merino underwear costs noticeably more per pair than synthetic quick-dry options from brands like ExOfficio, and that price gap is the main value tradeoff a buyer makes here. What merino offers in exchange is better odor resistance across multiple days of wear without washing, which matters more on trips with limited laundry access than the per-pair price. Merino also dries more slowly than nylon after a sink wash, so travelers doing frequent hand laundry in a hotel room may find the extra drying time inconvenient compared with faster-drying synthetic alternatives, even though the odor performance in between washes tends to be stronger.

Who should buy it

These hot pants suit travelers who prioritize odor resistance and comfort over the lowest possible price or fastest drying time, particularly on trips where laundry access is limited and underwear needs to be worn more than once between washes. The hot pants cut, offering more coverage than a brief, makes them a practical choice under skirts and dresses as well as for cold-weather layering. Budget-conscious travelers or those who wash underwear nightly and need it dry by morning may be better served by a synthetic quick-dry option that dries faster, even if it does not resist odor as well over multiple wears.
