Our Take
The Persimar Upgraded Thermal Underwear is a two-piece men’s base layer set (top and long johns) marketed for cold-weather use. The product listing highlights a fleece-lined interior and a low entry price, positioning it as a basic insulating layer to wear under riding gear.
This set will suit riders who want a simple, inexpensive thermal layer for dry, cold days where passive insulation is sufficient. The main trade-offs are limited published specification detail (fabric composition, size guidance and care instructions are not shown in the listing) and no built-in active heating — it’s a conventional fleece-lined base layer.

Scoring Breakdown
How It Performs
Design & Build Quality
The listing indicates a fleece-lined top and bottom set intended as a cold-weather base layer. Beyond the fleece lining there are no detailed material breakdowns or construction notes provided in the supplied facts. Expect a straightforward, low-profile design that’s meant to sit under outer layers rather than replace them.
Comfort & Fit
Fleece lining generally improves next-to-skin comfort and warmth. Because specific sizing and fabric stretch details are not supplied, riders should consult the product page size chart (or merchant sizing notes) before buying — fit is important for layering under motorcycle gear.
Performance
As a passive insulating layer, the set should add warmth on cold rides without bulk. It does not include active heating or technical insulation ratings, so it’s best for moderate cold or as part of a multi-layer system on colder rides.
Features
Key feature called out in the listing is the fleece lining and the fact it’s a two-piece set (top and long johns). The product summary does not list reflective panels, moisture-wicking claims, or reinforced areas specific to motorcycle use.
Ease of Use
Simple to put on and wear under motorcycle kit. Care instructions are not supplied in the product facts; check the product page for washing guidance. No electronics or special maintenance are required.
Battery Life
Not applicable — this is a non-electronic thermal base layer.
Durability
Durability details are not provided in the supplied facts. The average customer rating (4.6 from 313 reviews) suggests many buyers find it satisfactory, but the listing does not give fabric weight, seam construction or abrasion-resistance data to judge long-term durability.
Value for Money
The current listing price ($19.99) places this set in the budget segment. Given the fleece lining and two-piece format, it represents strong upfront value for riders who need inexpensive passive insulation and do not require technical features.
Real-World Use
Use this beneath a textile or leather outer layer on cold, dry rides where passive insulation is sufficient. It’s not a substitute for a heated vest or a technical insulating mid-layer on very cold or wet rides. Verify sizing before purchase to avoid tight or bulky layers that interfere with movement or gear fit.
Comparison With Competitors
For riders who need higher levels of warmth or active heating, battery-powered heated vests offer zone-controlled warmth and are a different product category (see our "SNOW LEOPARD Heated Vest Review: 6-Zone Men's Battery Vest" for a comparison). Compared with mid- to high-end technical base layers, this set trades advanced fabric specs and documentation for a lower price.
Fit & Suitability
Who Is This Product For?
Who Should Buy It
Riders on a budget who want a fleece-lined base layer for everyday cold-weather commuting or as part of a layered system for weekend rides.
Who Should Consider Alternatives
Riders who need certified thermal protection, weatherproof technical base layers, or built-in heated garments. Also avoid if precise sizing and fabric composition are critical for you — those details aren’t supplied.

RiderInstinct Verdict
Final Verdict
The Persimar Upgraded Thermal Underwear set is an affordable, fleece-lined top-and-bottom base layer that delivers straightforward passive warmth and strong on-paper value. The main limitation is a lack of detailed material and sizing information in the supplied facts, so verify fit and care/warranty information on the product page before purchase. For riders who want simple insulation under motorcycle gear without extra features, it’s a sensible budget option.
